What Does BALR Stand For?

BALR stands for Broad Absorption Line Region

BALR, or Broad Absorption Line Region, refers to a specific region in astrophysical spectra characterized by broad absorption features. These regions are typically associated with quasars and active galactic nuclei, where outflowing gas interacts with the emitted radiation, leading to the absorption of certain wavelengths. The study of BALRs provides insights into the dynamics of accretion processes and the properties of interstellar and intergalactic matter, contributing to our understanding of the evolution of galaxies and the universe.
