- W1666284903 abstract "M84 is a giant elliptical galaxy located in the Virgo cluster. Prior imaging with the Hubble Space Telescope (HST) revealed a small, highly inclined, nuclear ionized gas disk, the kinematics of which indicate the presence of a 0.4 -1.5 billion solar mass black hole. Two prominent radio jets emerge perpendicular to the nuclear ionized gas disk terminating in large radio lobes that extend beyond the visible galaxy. Plausible kinematic models are used to constrain the size of the broad line region (BLR) in M84 by modeling the shape of the broad H-alpha emission line profile. The analysis indicates that the emitting region is large with an outer radius between ~ 7 and 9 pc, depending on whether the kinematic model is represented by a spherically symmetric inflow or a Keplerian disk. The inferred size makes the BLR in M84 the largest yet to be measured. The fact that the BLR in M84 is so large may explain why the AGN is unable to sustain the ionization seen there. Thus, the BLR in M84 is not simply that of a scaled down quasar." @default.
