What Does BALQSO Stand For?

BALQSO stands for Broad Absorption Line Quasi Stellar Object

BALQSO, or Broad Absorption Line Quasi Stellar Object, refers to a category of quasars characterized by broad absorption lines in their spectral emissions. These absorption features are typically associated with outflows of material moving at high velocities, which occur in the vicinity of supermassive black holes at the centers of distant galaxies. BALQSOs are important for understanding the properties of quasars, the mechanisms of active galactic nuclei, and the dynamics of gas in the intergalactic medium. Their study provides insights into the formation and evolution of galaxies in the universe.
