Star Formation Histories and Stellar Dynamics in the Central Galaxies of RX J0820.9+0752, A1835, and PKS 0745-191
Marie-Joëlle Gingras, B. R. McNamara, Alison L. Coil +5
We present Keck Cosmic Web Imager observations of stellar populations in three galaxies lying at the centers of cooling flow clusters. All three host rich molecular gas reservoirs…
Velocity Structure Correlations between the Nebular, Molecular, and Atmospheric Gases in the Cores of Four Cool Core Clusters
Muzi Li, B. R. McNamara, Alison L. Coil +6
We investigate the velocity structure of nebular gas in the central galaxies of four clusters: Abell 1835, PKS 0745-191, Abell 262, and RXJ0820.9+0752, using data from the Keck Cos…
HST Observations within the Sphere of Influence of the Powerful Supermassive Black Hole in PKS0745-191
Julie Hlavacek-Larrondo, Hyunseop Choi, Minghao Guo +18
We present Space Telescope Imaging Spectrograph observations from the Hubble Space Telescope of the supermassive black hole (SMBH) at the center of PKS0745-191, a brightest cluster…
Complex Velocity Structure of Nebular Gas in Active Galaxies Centred in Cooling X-ray Atmospheres
Marie-Joëlle Gingras, Alison L. Coil, B. R. McNamara +6
[OII] emission maps obtained with the Keck Cosmic Web Imager (KCWI) are presented for four galaxies centered in cooling X-ray cluster atmospheres. Nebular emission extending tens o…
Probing the disk-corona systems and broad line regions of changing-look quasars with X-ray and optical observations
Xiangyu Jin, John J. Ruan, Daryl Haggard +8
"Changing-look" quasars are a new class of highly variable active galactic nuclei that have changed their spectral type over surprisingly short timescales of just a few years. The…
Thermally Unstable Cooling Stimulated by Uplift: The Spoiler Clusters
C. G. Martz, B. R. McNamara, P. E. J. Nulsen +9
We analyzed Chandra X-ray observations of five galaxy clusters whose atmospheric cooling times, entropy parameters, and cooling time to free-fall time ratios within the central gal…
