The impact of Blazars and Black Holes on the surrounding matter is profound. When matter gets accreted by a Black Hole, it forms an accretion disk, releasing tremendous amounts of energy in the form of radiation and jets. These energetic jets, composed of charged particles, can travel vast distances and interact with the surrounding interstellar medium. This interaction can drive shockwaves, compress gas and dust, trigger the formation of new stars, and even influence the evolution of entire galaxies.
Blazars, being a subtype of active galactic nuclei, exhibit intense gamma-ray emissions. The production of gamma-rays in Blazars occurs due to the interaction between high-energy particles and ambient photons. These gamma-rays can then participate in a cascade of secondary particle production, resulting in the generation of a diverse spectrum of radiation. This radiation interacts with the surrounding matter, contributing to the overall energy budget of the galaxy and influencing its evolution.
