Astrophysicists explain the mysterious behavior of cosmic rays

Scientists developed a model which explains the nature of high-energy cosmic rays in our Galaxy


A team of scientists from Russia and China has developed a model which explains the nature of high-energy cosmic rays (CRs) in our Galaxy. These CRs have energies exceeding those produced by supernova explosions by one or two orders of magnitude. The model focuses mainly on the recent discovery of giant structures called Fermi bubbles.

One of the key problems in the theory of the origin of cosmic rays (high-energy protons and atomic nuclei) is their acceleration mechanism. The issue was addressed by Vitaly Ginzburg and Sergei Syrovatsky in the 1960s when they suggested that CRs are generated during supernova (SN) explosions in the Galaxy. A specific mechanism of charged particle acceleration by SN shock waves was proposed by Germogen Krymsky and others in 1977. Due to the limited lifetime of the shocks, it is estimated that the maximum energy of the accelerated particles cannot exceed 1014-1015 eV (electronvolts).

The question arises of how to explain the nature of particles with energies above 1015 eV. A major breakthrough in researching the acceleration processes of such particles came when the Fermi Gamma-ray Space Telescope detected two gigantic structures emitting radiation in gamma-ray band in the central area of the Galaxy in November 2010. The discovered structures are elongated and are symmetrically located in the Galactic plane perpendicular to its center, extending 50,000 light-years, or roughly half of the diameter of the Milky Way disk. These structures became known as Fermi bubbles. Later, the Planck telescope team discovered their emission in the microwave band.

The nature of Fermi bubbles is still unclear, however the location of these objects indicates their connection to past or present activity in the center of the galaxy, where a central black hole of 106 solar masses is believed to be located. Modern models relate the bubbles to star formation and/or an energy release in the Galactic center as a result of tidal disruption of stars during their accretion onto a central black hole. The bubbles are not considered to be unique phenomena observed only in the Milky Way and similar structures can be detected in other galactic systems with active nuclei.

Dmitry Chernyshov (MIPT graduate), Vladimir Dogiel (MIPT staff member) and their colleagues from Hong Kong and Taiwan have published a series of papers on the nature of Fermi bubbles. They have shown that X-ray and gamma-ray emission in these areas is due to various processes involving relativistic electrons accelerated by shock waves resulting from stellar matter falling into a black hole. In this case, the shock waves should accelerate both protons and nuclei. However, in contrast to electrons, relativistic protons with bigger masses hardly lose their energy in the Galactic halo and can fill up the entire volume of the galaxy. The authors of the paper suggest that giant Fermi bubbles shock fronts can re-accelerate protons emitted by SN to energies greatly exceeding 1015 eV.

Analysis of cosmic ray re-acceleration showed that Fermi bubbles may be responsible for the formation of the CR spectrum above the “knee” of the observed spectrum, i.e., at energies greater than 3×1015 eV (energy range “B” in Fig. 2). To put this into perspective, the energy of accelerated particles in the Large Hadron Collider is also ~1015 eV.

“The proposed model explains the spectral distribution of the observed CR flux. It can be said that the processes we described are capable of re-accelerating galactic cosmic rays generated in supernova explosions. Unlike electrons, protons have a significantly greater lifetime, so when accelerated in Fermi bubbles, they can fill up the volume of the Galaxy and be observed near the Earth. Our model suggests that the cosmic rays containing high-energy protons and nuclei with energy lower than 1015 eV (below the energy range of the observed spectrum’s “knee”), were generated in supernova explosions in the Galactic disk. Such CRs are re-accelerated in Fermi bubbles to energies over 1015 eV (above the “knee”). The final cosmic ray distribution is shown on the spectral diagram,” says Vladimir Dogiel.

The researchers have proposed an explanation for the peculiarities in the CR spectrum in the energy range from 3×1015 to 1018 eV (energy range “B” in Fig. 2).

The scientists have proven that particles produced during the SN explosions and which have energies lower than 3×1015 eV experience re-acceleration in Fermi bubbles when they move from the galactic disk to the halo. Reasonable parameters of the model describing the particles’ acceleration in Fermi bubbles can explain the nature of the spectrum of cosmic rays above 3×1015 eV. The spectrum below this range remains undisturbed. Thus, the model is able to produce spectral distribution of cosmic rays that is identical to the one observed.

Very confusing: I Believe that every 1015 eV and 1014 eV in the article should read 1e15 eV and 1e14 eV or other scientific notation.

From the axis of the graph it appears that 1015 eV is actually 10^15 eV (ten raised to the power of fifteen).
Using the ^ symbol avoids the confusion of having e exponent and e electron in the same formula, not to mention the fact that 1^15 = 1 🙂

There are lots of confusing idioms. Consider all the things each Greek letter can represent. link
The ‘e’ notation is very common in computer code because it is very easy/efficient to type on the keyboard and it’s easy to write an interpreter/compiler to decode it.
Most STEM educated people will be familiar with the ‘e’ notation and those not so educated (ie. those with a PhD in Postmodern Womens’ Studies) might not understand what the superscript means anyway. All of math is evil because it was dreamed up by old dead white men. The use of numbers disadvantages people with fewer than ten fingers and toes and is therefore politically incorrect. LOL

Well I’m familiar with e notation ( which has it’s roots in early programming like FORTRAN done on punch cards ) however I have no idea what a STEM is. One of the those futile obscure acronyms that waste more time than they pretend to save.
The caret symbol would seem best here since super script characters can be too small to be clearly readable.
those with a PhD in Postmodern Womens’ Studies would probably get confused by eV , never mind the numbers that go before it. If you don’t understand the units, the numbers don’t matter. ( except in sociology and Postmodern Womens’ Studies where graphs have no scale , no zero and no units anyway ).

They’ve pictured it like a big accelerator, like CERN have made or even inside the magnetron of your microwave oven – the poor little charged foogers find themselves in perpendicular electric/magnetic fields and just go round and round ever faster.
Aw man, I’ve just worked out the GHGE..
Goes like this:
The Earth’s magnetic field (it goes up and down apart from at the equator) , at right angles electric fields produced by all the power lines that we’ve built (they go along the surface, usually) are acter-intar-rackteracking-ting with all that charged shit coming from the sun.
And they do that all the time.
‘cept at night and maybe in an elipsce.
And English summers when its cloudy.
All the time.
All these little boogers get hot and bothered just going round & round up the the atmosphere – c’mon, get real – wouldn’t you too? So the hot sky makes the dirt hot.
And there it is – the sky really is a microwave oven and WE DID IT

Mark 7:16am, the experiment in your video is a strawman constructed so as to easily stab that strawman.
A clue ought to be found in what the guy calls the first thermal image. Note the holes show a different color than the blocks into which they are drilled yet as he notes the hole surfaces are the same temperature as the object’s other surfaces. How can that be if Planck’s law is valid for the holes of this experiment? It can’t. Planck’s law and thus Kirchhoff’s law are not applicable to the holes of this experiment. His conclusions are thus inappropriate; the experiments do not invalidate Kirchhoff’s Law.
Planck developed the math in his treatise so that his law will only be applied to objects with all positive radii much larger than the wavelength of light of interest. That means only applicable to objects that do not radiate to themselves. Unfortunately for the video guy the surfaces of the holes drilled in his various objects radiate to themselves accounting for the difference in thermal image color shown in the video.
Testing has shown Planck and Kirchhoff radiation laws are applicable to the earth as an oblate spheroid under solar and terrestrial illumination (significantly positive radii much larger than the wavelength of light of interest, thus negligible diffraction).

Here is another trick like complete lack of understanding of invalidation and the implications of the invalidation.
It seems many people with actual physics PhDs don’t even understand Kirchhoff’s law concerning Astronomy and thermal radiation
“Pierre Robitaille is a world class crank who believes that he has discovered a serious flaw in the theory of thermal radiation. His “proof of invalidity” is vacuous. He’s missed the simple point that a perfect blackbody is from the outset only a theoretical idealization which is nevertheless very much relevant to the theory of actual thermal radiation from real cavities.
He believes that the source of the cosmic microwave background radiation, which has been experimentally measured by many satellite observations and which has almost exactly a perfectly Planckian form for the radiation distribution, is the earth’s oceans, a completely ludicrous suggestion on its face”
^^ from a physicist.. No the CBR is a result of data processing not experimental measurement by many satellite observations and he ignores the problem with microwaves and COBE and the fact the Planck satellite has the heat shield bolted to the black body payload (in the sat designs) and so the payload is useless, convection pollutes it.
Not that you addressed the issue in your post Trick, you didn’t, and this one attempts to, and fails, with the straw man “perfect black body”. Kirchoff stated the material make up of the cavity is arbitrary, that it does not matter, which is proven incorrect.
For the standard model to be valid, for quantum physics to be valid, cavities must be arbitrary, and they are not, you are lost in space

Its kind of sobering to consider how reliable the electronics has been. Mostly … because of the size of transistors used. Back 40+ years ago, you could actually SEE transistors on a computer chip with a jeweler’s loupe. Yep, tiny, but not fractions-of-a-wavelength-of-light small, as they are today. 3 to 5 μm linewidth. Usually much larger for power lines and so on.
A cosmic ray, crashing thru the probe’s shell, structural stuff, “computer can” and little ceramic chip holders stands a pretty good chance of hitting something, and quite literally on a tiny scale, explode into a cascade of charged particles. On the “μm” scale.
Hit a Pioneer transistor with that cascade, and sure… it might suddenly conduct when it wasn’t supposed to. For a few nanoseconds, at most. Being big ‘n’ thick, it isn’t usually damaged, just jostled a bit. Hit a present-day ThreadRipper chip having 10 billion transistors crammed into a US quarter-sized chip, and that cascade won’t just slam into hundreds of adjacent transistors, but the particle energy is high enough to more or less permanently disable the transistors from future ‘proper’ functioning.
Might not sound like the end of the world, but if the explosion site is in the middle of a CPU, it will be Unhappy Days for the CPU. For memory, it is better: you lose a bit; if the designers employed mathematical scatter-gather error-correction/redundancy to a high degree, you mightn’t lose anything. But that area once hit becomes more susceptible to future data loss. ECC is like that. It works the first time (at a position), and who knows, maybe a second time. But rarely a 3rd, 4th or subsequent hit.
0.1 MHz clock rate, micro (not nano-) scopic transistors, “thick”, “fat” and collision tolerant transistors. Performance by today’s standards of you’ve-got-to-be-kidding-me slow, but for a Scientific Instrument, it was plenty good.

S class 10 K rad hard parts have very specific design rules and structures: Up down ISO. deep EPI, graded drains to prevent hot electron damage on CMOS, no traces over active regions, Back side grinding to create traps, gold die attach, extra thick double layer bond pads to prevent purple plague, silicon doped Al contacts to prevent spiking, double layer Al traces to decrease electromigration, guard rings, even the top passivation is carefully controlled, etc, etc.
Some very ignorant individuals have suggested puchasing commercial parts and then testing them to mil spec or even S class. Mil spec -55C to +125C are designed to different design rules. S class 10K rad hard are further different from Mil or commercial in just about every respect.

Interesting, but since Moore’s Law is really a law of manufacturing costs, it’s a safe bet you could throw more redundancy in there at a similar rad spec for less money today and end up with better MTBF overall.

This Russian-Chinese theory or model is anyway much more convincing than the present theory, which is that Cosmic Rays have an origin in the supernova events. There are at least two challenges: There is only one SN in every hundred year in a galaxy and CRs seem to come from all directions with the constant speed. Quite lately they have noticed that a pretty great deal of CRs originate from the Sun.

August 19, 2017 1:26 pm

Thank you Anthony.
A very interesting article.
First, just looking at that beautiful picture of the Galaxy and the Fermi bubbles, one is left with only one thing to really say……….what a breath taking picture, but none the less a phony one.
The model output data for that picture completely dwarfs in a cosmic scale the input data.
The distance of the Fermi detection point from such bubbles is far too close for such a picture to be contemplated and considered as representing some thing real if the amount of observational data is not increased and amplified by a cosmic factor.
The raw data can not ever produce that picture unless the model it goes through has an “insane” generic data algorithm to compensate for the missing data required for such a picture.
Our Earth and our Sun are too too close too these Fermi bubbles, according to the Fermi bubbles size and the distance of our solar system to the center of the Milky Way.
The out put of the model is a product driven to produce a desired and expected result, which will not upset a lot a lot of other scientistas. The model seems to be one tailored to just out put such a result.
The picture in question is due to a Fermi view point (Earth view point), that as far as I can tell, is in a Zoom out at 40K X to 80K X…… where K stands for thousand.
The way that picture stands it points out at the need of having Fermi data not confuse and invalidate the output from the light models, the models that are fed with data from Hubble and such as……..
The main problem, according to Fermi cosmic ray data is that the Cosmic ray source is far too big (very big radius) for a comfort, but with a stretch, like in this case, still not a big anomaly, if pictured and considered as per an by the model in question……..
Will be interesting to have an argument about this.

“The discovered structures are elongated and are symmetrically located in the Galactic plane perpendicular to its center…”
The structures are symmetrical, but are very much NOT located in the Galactic Plane. They are above and below the GP or symmetrically located with respect to the GP. They are not “in” it, as the diagram clearly shows.

And that is the model “trick”, no touch of GP, and that (the no touch) is what is impossible for the raw data to show or point out at……..unless the model is tailored to do, I think.

Interesting article but I am a bit concerned about…
“The scientists have proven that particles produced during the SN explosions and which have energies lower than 3×1015 eV experience re-acceleration in Fermi bubbles when they move from the galactic disk to the halo.”
Having a model produce a match for measurements, while certainly much better than the priests of AGW ever achieve, is NOT proof.
I’m also a little curious what happens to the particles that lie between 10^15 eV and 3 x 10^15 eV. – are there any who get just a gentle ‘push’ to (say) 2 x 10^15 eV?

Totally off topic, but when I saw the first graphic I thought: whoa sure looks like a p-shell. Fractal shapes repeating at different scales?

Wow, a model that actually matches the observed data. Climate Scientists take note!

Note that this is a press release about a paper that was posted in January and still has 0 citations, see “Origin of X-ray and gamma-ray emission from the Galactic central region” at Google Scholar. So among thousands of similar papers that are being written every year, you have picked one that belongs to the 10% of the least successful ones.

It seems that some scientists find themselves on the right path to know the causes of such phenomena in the universe, but none of them have yet understood what matter is, how and from what it originates and how it disappears. The only logical thing in this article is that they believe that these rays originated from the supernova, but none of them know how and why the supernova is produced.
Here’s how to learn something from the structure of the universe:
-Universum is an infinite sphere, filled with substance, which we can call AETHER. From this substance, matter arises through high aether bibs, which form strings into three spatial directions and in their cross-sections the matter is formed in “solid state” -quarks, and in “liquid state” -gluones.
Gluones hold the 3kg quadruple quarks (3 quarks and 3 gluons), and in particular a “fluid energy state” of the “free gluon” substance is formed, which can be “evaporated,” “condensed,” and split into a pair of particles “electron and Pozitron.
At the site of vibrations, a quark-gluon plasma formed from which the celestial body is formed – a magnetar, and it transforms into: a quasar, a dual star, and later a neutron star that explodes as a supernova and forms subatomic particles, atoms, Elements, gas clothing, baby bodies.
Very important phenomena:
 -gravitation: the residual unbalanced state between the ether and the “solid state” of the matter (“family backlog”)
 – magnetism-is, the backward link between ether and free gluons.
Gravity has the task of bringing matter into the masses of mass, until critical mass and critical gravity reach. Then the material is transformed back into the form of the ether from which it was formed, which takes place in black holes (the “tomb” of matter and the end of the closed circle of the process of formation and dissolution of matter). You understand this as my copyright, which I leave as proof of what I wrote and to whom I wrote.

Thus, the model is able to produce spectral distribution of cosmic rays that is identical to the one observed.

And that is how models SHOULD be used in science. You propose a theory, build a model on the theory and THEN compare the model output to REAL WORLD data. If the model is close you win (well not quite as you could have been luck for one case, multiple comparisons are needed). If the model isn’t close you lose and your theory is wrong, see climate models for examples of losing.

Double-layers in plasma can accelerate charged particles to very high energies.
