High-energy cosmic ray sources can be mapped for the first time

Instantly, certain stocks rose: in particular, three kinds of candidate objects that threaded a relatively common index in the universe and were special enough to produce oh-my-god particles.

Icarus Stars

In 2008, Farrar and an assistant Recommended Disasters called tidal disturbances (TDES) can be the source of ultra-high-energy cosmic rays.

A TDE occurs when a star pulls an icaras and moves very close to a supermassive black hole. The front part of the star feels so much heavier than its back that they scatter and fall into the abyss and the irl vortex lasts about a year. As it settles, two jet elements – the tribal shadows of the disrupted star – shoot in opposite directions from the opposite blackhole. The shock waves and magnetic fields in these beams can then plan to accelerate the nucleus to superconducting forces before slingshot in space.

Tidal disturbance events occur approximately once every 100,000 years in each galaxy, which is the cosmic equivalent of occurring everywhere. Since galaxies detect matter distribution, TDEs may explain the success of Ding, Globus, and Faraday’s uninterrupted models.

Moreover, a relatively short flash of a TDE solves other puzzles. As soon as the cosmic ray of a TDE reaches us, the TDE will remain dark for thousands of years. Other cosmic rays from the same TDD can take different bend paths; May not come for centuries. The transient nature of a TDE may explain why there seems to be such a low pattern of cosmic ray arrival directions, with no correlation with the position of the known object. “I now believe they are mostly transient,” Farrar said of the source of the ray.

The TDD hypothesis has recently received another impetus from an observation Report Nature Astronomy In February

Robert SteinOne of the authors of the paper is operating a telescope called Zuiki Transient Factory in California in October 2019 when a warning came from the Antarctic Icecube Neutrino Observatory. The ice cube identified a particularly powerful neutrino. Even high-energy neutrinos are formed when light or matter is scattered in the environment in which the higher cosmic rays are formed.

Stein swept the telescope in the direction of the arrival of the Icecuber neutrino. “Immediately a tidal wave occurred from the position where the neutrino came from,” he said.

The paper makes it even more probable that TDEs are at least one source of energetic cosmic rays. However, the power of neutrinos was probably too low to prove that TDEs produce extremely high-energy rays. Some researchers strongly question whether these observed momentary forces can accelerate the nucleus to the final end of the spectrum; Theorists are still exploring how events can accelerate particles in the first place.

Meanwhile, other information attracts the attention of some researchers elsewhere.

Starburst Superwinds

Cosmic ray observations, such as the Aogar and telescope arrays, have found a few hot spots on the arrival of very high-energy cosmic rays – small, fine concentrations. In 2018, Agar Published The result of the comparison of its hot spots with the positions of astronomical objects within a few hundred million light years. (Cosmic rays from far and wide will lose too much energy in the collision of the meridian))

In cross-correlation competition, deflation is the exceptionally well-executed performance of any kind of object based on cosmic ray experience – understandable. The strongest correlation, however, surprises many experts: about 10 percent of the rays come from within 13 degrees of the direction of the so-called “Starburst galaxies.” “They weren’t originally on my plate,” he said Michael Unger Auger is a member of the team at the Karlsruhe Institute of Technology.
