blazar
Definition
- A blazar is a class of active galaxy that includes BL Lacertae objects, high polarization quasars (HPQs), and optically violent variables (OVVs). Blazars are characterized by strong, compact, flat-spectrum radio emission. They also show continuum domination of the optical emission, and/or significant optical polarization, and/or strong gamma-ray emission, and/or significant changes in optical flux on short time scales. They are believed to be active galactic nuclei (AGM) whose jets are aligned within 10° of our line of sight.
