A Blazing Beacon in the Cosmic Tapestry

What is a Blazar?

A blazar is a type of active galactic nucleus (AGN) that exhibits highly energetic, relativistic jets emitted from the accretion disk surrounding a supermassive black hole. These jets point directly towards Earth, resulting in a blazing appearance due to Doppler boosting. The term "blazar" is derived from the combination of "BL Lac object" and "quasar," reflecting their shared properties.

Identifying IRAM256-1567A2

IRAM256-1567A2, located in the constellation of Pegasus at a distance of approximately 8.6 billion light-years from Earth, is classified as a flat-spectrum radio quasar (FSRQ). FSRQs are a subclass of blazars characterized by their strong radio emission and weak optical emission lines.
