Background Quasars in the Vicinity of M31/M33 with LAMOST
Presenter: Zhiying Huo (National Astronomical Observatoreis, Chinese Academy of Sciences)
In this work, we present quasars discovered in fields in the vicinity of the
Andromeda (M31) and Triangulum (M33) galaxies with LAMOST, which represent a significant increase in the number of identified quasars in fields in the vicinity of M31 and M33. Up to now, there have been a total of ~4000 quasars discovered by LAMOST in this area. The much enlarged sample of known quasars in this area can potentially be utilized to construct a precise astrometric reference frame for the measurement of minute proper motions of M31, M33 dan the Local Group of galaxies. Moreover, in this sample, there are hundreds of brighter quasars. These bright quasars provide an invaluable sample to study the kinematics and chemistry of the interstellar/intergalactic medium of the Local Group.
