To characterize the oscillation properties of the disk and predict the strength of gravity, X-ray observations are essential. Obtaining QPO frequencies from X-rays is a significant step in understanding the characteristics of both the black hole and the disk. However, understanding the physical ...
however, suggests that this excess in gamma-rays could be produced by a population of point sources (i.e., sources of energy), some of which may have already been observed in the past.

Fig. 1. X-ray and gamma-ray emission bubbles (Fermi Bubbles) in the Milky Way. CREDIT NASA 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...

radiative zone (where gamma rays spend 171 thousand years colliding with matter, getting longer wavelength at each collision, until they leave) but somebody should probably learn about all the different zones at some point and make sure the text is correct. I never knew the sun was so complex...
“I believe that, with this study, we have uncovered the tip of the iceberg,” Shprits said. “We still need to fully understand how these electrons are accelerated, where they originate, and how the dynamics of the belts are different for different storms.” ...
