a continuous distribution of pulses from zero to a certain maximum height which corresponds to the continuous distribution of Compton electrons produced in the absorption of the gamma-rays.

"This particular object radiates only faintly in the energy region where gamma rays have an energy of a few hundred million electron volts," explains Gaidos. "This is the region where the detector on ...

In late 2022, gamma-ray activity of 3C 216 started to increase ... 3C 216 can be interpreted as an outburst of synchrotron self-Compton (SSC) radiation. Such an outburst is likely associated ...

Chandra and Hubble are the only two remaining Great Observatories, NASA’s four large telescopes launched between 1990 and 2003, marking a golden age of cosmic discovery (the Compton Gamma Ray ...
