A series of shocks and edges in Abell 2219
R. E. A. Canning, S. W. Allen, D. E. Applegate +6
We present deep, 170 ks, Chandra X-ray observations of Abell 2219 (z=0.23) one of the hottest and most X-ray luminous clusters known, and which is experiencing a major merger event…
The Megasecond Chandra XVP Observation of NGC 3115: Witnessing the Flow of Hot Gas within the Bondi Radius
Ka-Wah Wong, Jimmy A. Irwin, Roman V. Shcherbakov +3
Observational confirmation of hot accretion model predictions has been hindered by the challenge to resolve spatially the Bondi radii of black holes with X-ray telescopes. Here, we…
Suzaku Observations of the X-ray Brightest Fossil Group ESO 3060170
Yuanyuan Su, Raymond E. White, Eric D. Miller
"Fossil" galaxy groups, each dominated by a relatively isolated giant elliptical galaxy, have many properties intermediate between groups and clusters of galaxies. We used the {\sl…
Ripping Apart at the Seams: The Network of Stripped Gas Surrounding M86
S. Ehlert, N. Werner, A. Simionescu +4
We present a new study of the Virgo Cluster galaxies M86, M84, NGC 4338, and NGC 4438 using a mosaic of five separate pointings with XMM-Newton. Our observations allow for robust m…
High Spectral Resolution Measurement of the Sunyaev-Zel'dovich Effect Null with Z-Spec
M. Zemcov, J. Aguirre, J. Bock +15
The Sunyaev-Zel'dovich (SZ) effect spectrum crosses through a null where dT_CMB = 0 near nu_0 = 217 GHz. In a cluster of galaxies, nu_0 can be shifted from the canonical thermal SZ…
Core-collapse supernova enrichment in the core of the Virgo Cluster
E. T. Million, N. Werner, A. Simionescu +1
Using a deep (574 ks) Chandra observation of M87, the dominant galaxy of the nearby Virgo Cluster, we present the best measurements to date of the radial distribution of metals in…
Resolving the Bondi Accretion Flow toward the Supermassive Black Hole of NGC 3115 with Chandra
Ka-Wah Wong, Jimmy A. Irwin, Mihoko Yukita +3
Gas undergoing Bondi accretion onto a supermassive black hole (SMBH) becomes hotter toward smaller radii. We searched for this signature with a Chandra observation of the hot gas i…
A high-frequency study of the Sunyaev-Zel'dovich effect morphology in galaxy clusters
D. A. Prokhorov, S. Colafrancesco, T. Akahori +3
High-frequency, high-resolution imaging of the Sunyaev-Zel'dovich (SZ) effect is an important technique to study the complex structures of the atmospheres of merging galaxy cluster…
Violent interaction between the AGN and the hot gas in the core of the galaxy cluster Sersic 159-03
N. Werner, M. Sun, J. Bagchi +7
We present a multi-wavelength study of the energetic interaction between the central active galactic nucleus (AGN), the intra-cluster medium, and the optical emission line nebula i…
Feedback under the microscope: thermodynamic structure and AGN driven shocks in M87
E. T. Million, N. Werner, A. Simionescu +5
(abridged) Using a deep Chandra exposure (574 ks), we present high-resolution thermodynamic maps created from the spectra of 16,000 independent regions, each with 1,000…
Feedback under the microscope II: heating, gas uplift, and mixing in the nearest cluster core
N. Werner, A. Simionescu, E. T. Million +11
Using a combination of deep 574ks Chandra data, XMM-Newton high-resolution spectra, and optical Halpha+NII images, we study the nature and spatial distribution of the multiphase pl…
Ram pressure stripping of the cool core of the Ophiuchus Cluster
E. T. Million, S. W. Allen, N. Werner +1
(abridged) We report results from a Chandra study of the central regions of the nearby, X-ray bright, Ophiuchus Cluster (z = 0.03), the second-brightest cluster in the sky. Our stu…
Chandra measurements of non-thermal-like X-ray emission from massive, merging, radio-halo clusters
E. T. Million, S. W. Allen
We report the discovery of spatially-extended, non-thermal-like emission components in Chandra X-ray spectra for five of a sample of seven massive, merging galaxy clusters with pow…
Dark Matter and Baryons in the Most X-ray Luminous and Merging Galaxy Cluster RX J1347.5-1145
Maruša Bradač, Tim Schrabback, Thomas Erben +12
The galaxy cluster RX J1347-1145 is one of the most X-ray luminous and most massive clusters known. Its extreme mass makes it a prime target for studying issues addressing cluster…
