blazars

A very small percentage of the quasar population that appears to share some of the extreme characteristics of the BL Lac objects as a consequence of relativistic beaming (see synchrotron emission). The luminosity of the emission lines stays constant while the continuum emission varies dramatically by factors as large as a hundred. The quasar is highly polarized and exhibits superluminal motion at radio wavelengths.

Blazars are galaxies containing supermassive black holes that are able to release narrowly collimated jets of energetic particles that leap out of their galaxies and streak across the cosmos at nearly the speed of light.
Within hours the space-based Neil Gehrels Swift Observatory had identified the particle's possible source: the blazar TXS 0506+056, whose light and particles travel 3.8 billion light-years to reach Earth.
Kirk and Mastichiadis (1999) [11] put forward that, for blazars, the spectral shape can be influenced by the synchrotron particle acceleration and synchrotron cooling.

It's already found hundreds of massive black holes known as blazars and has imaged the coldest known stars in the universe.
The fastest ' things' i n the Universe are blobs of superheated plasma that are ejected from black holes that are in the cores of extremely active galaxies known as blazars. These blobs, with as much mass as Jupiter, have been observed to travel at 99.99% of the speed of light.
About two-thirds of the material is dedicated to invited talks covering black holes, blazars, active galactic nuclei and galactic masers, variability and high brightness objects, and radio stars.
Researchers at The University of Texas at Austin have found new evidence to suggest that all radio-loud quasars may be blazars and that the differences between them may be related to the angle from which they are viewed.
And the new discoveries pertain to objects and phenomena with such peculiar names as "gamma-ray bursts," "blazars," a "fountain of antimatter," and a "gamma-ray halo" around the Milky Way.
