Astronomers Detect Extraordinary Gamma-Ray Flare From Blazar TXS 2013+370 Jets Aimed at Earth: What Makes Blazars Unique Structure and Classification of Blazars Astronomers have used very long baseline interferometry (VLBI) to study the gamma-ray loud blazar known as TXS 2013+370. The findings, shared on the arXiv preprint server on 19 November, revealed the presence of an extraordinary gamma-ray flare from the source. Blazars are compact, quasar-like celestial objects powered by supermassive black holes located at the centers of giant active elliptical galaxies. They form part of a broader category of active galaxies that host active galactic nuclei (AGN) and are the most frequent sources of gamma-ray emissions beyond the Milky Way. A defining characteristic of blazars is the presence of highly energetic, relativistic jets that are aligned almost directly towards Earth. Blazars are generally grouped into two types, based on their optical signatures. Flat-spectrum radio quasars (FSRQ...
