[110.05] Gas Kinematics in the Central Regions of NGC 1275

M. Harrison, G. Canalizo (IGPP/UC Riverside)

NGC 1275 is a well studied and exotic FRI galaxy at the center of the Perseus Cluster. In the past, radio and optical variability has been examined showing periods of increased luminosity, which is consistent with the accretion of gasses from a recent merger. A high velocity system has been identified that appears to be falling inward, towards the active nucleus from the northwest at ~3000 km/s. We combined very deep Keck ESI spectroscopy with archival HST WFPC2 images to construct a velocity map centered on the nucleus, with the slit roughly in the direction of the high velocity system. These data along with VLA radio images were used to study the kinematics of the circumnuclear gas, the high velocity system, and to look for evidence of interaction between the radio source and the surrounding environment. Line ratios in the region were also inspected to investigate different ionization mechanisms that might be present.
