PMN J1310–5552: A Gamma-Ray-emitting Blazar Candidate Harboring a Cosmic Monster

The Astrophysical Journal
Relativistic jets manifest some of the most intriguing activities in the nuclear regions of active galaxies. Identifying the most powerful relativistic jets permits us to probe the most luminous accretion systems and, in turn, the most massive black ...

Role of Magnetic Reconnection in Blazar Variability Using Numerical Simulation

The Astrophysical Journal
Fast γ -ray variability in blazars remains a central puzzle in high-energy astrophysics, challenging standard shock acceleration models. Blazars, a subclass of active galactic nuclei with jets pointed close to our line of sight, offer a unique view into ...

The Proton Blazar

, 1993
Considering shock-accelerated protons in addition to electrons in a synchrotron radio jet naturally produces the observed X- through gamma ray continuum emission of flat-spectrum radio-loud AGN, whereas the corresponding shock-accelerated electrons produce the infrared through optical continuum.
