Discovery of galactic microblazar candidate IRAS 18293–0941

Overview

An international team of astronomers has identified IRAS 18293–0941, a strong candidate for a ‘microblazar’ within the Milky Way. Located approximately 12,000 light-years from Earth, the system confirms a theoretical prediction that has existed for about 30 years.

The system consists of a massive, hot star and a stellar-mass black hole—roughly ten times the mass of the Sun—orbiting each other every 11.38 days. As the black hole accretes material from its companion, it ejects bipolar plasma jets at speeds reaching about 75% of the speed of light. It is classified as a microblazar because one jet is oriented almost directly toward Earth, causing it to appear significantly brighter due to relativistic effects.

The discovery, involving researchers from the University of Jaén and the National University of La Plata, was achieved by synthesizing multi-spectrum data, including X-rays, gamma rays, radio waves, and visible light, over a three-year period.
