Mapping Gas Accretion and Stellar Kinematics to Sub-kiloparsec Scales in NGC 4696 with JWST/NIRSpec
Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35
We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
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…
Constraints on thermal conductivity in the merging cluster Abell 2146
A. Richard-Laferrière, H. R. Russell, A. C. Fabian +9
The cluster of galaxies Abell 2146 is undergoing a major merger and is an ideal cluster to study ICM physics, as it has a simple geometry with the merger axis in the plane of the s…
Discovery of inverse-Compton X-ray emission and estimate of the volume-averaged magnetic field in a galaxy group
F. Mernier, N. Werner, J. Bagchi +6
Observed in a significant fraction of clusters and groups of galaxies, diffuse radio synchrotron emission reveals the presence of relativistic electrons and magnetic fields permeat…
The structure of cluster merger shocks: turbulent width and the electron heating timescale
H. R. Russell, P. E. J. Nulsen, D. Caprioli +10
We present a new 2 Ms Chandra observation of the cluster merger Abell 2146, which hosts two huge M~2 shock fronts each ~500 kpc across. For the first time, we resolve and measure t…
Extended radio emission in the galaxy cluster MS 0735.6+7421 detected with the Karl G. Jansky Very Large Array
T. Bégin, J. Hlavacek-Larrondo, C. L. Rhea +7
MS 0735.6+7421 () is a massive cool core galaxy cluster hosting one of the most powerful active galactic nuclei (AGN) outbursts known. The radio jets of the AGN have car…
VLA resolves unexpected radio structures in the Perseus cluster of galaxies
Marie-Lou Gendron-Marsolais, Charles L. H. Hull, Rick Perley +10
We present new deep, high-resolution, 1.5 GHz observations of the prototypical nearby Perseus galaxy cluster from the Karl G. Jansky Very Large Array. We isolate for the first time…
On the relation between mini-halos and AGN feedback in clusters of galaxies
A. Richard-Laferrière, J. Hlavacek-Larrondo, R. S. Nemmen +10
A variety of large-scale diffuse radio structures have been identified in many clusters with the advent of new state-of-the-art facilities in radio astronomy. Among these diffuse r…
A Multiwavelength Study of the Massive Cool Core Cluster MACS J1447.4+0827
M. Prasow-Émond, J. Hlavacek-Larrondo, C. L. Rhea +8
Clusters of galaxies are outstanding laboratories for understanding the physics of supermassive black hole feedback. Here, we present the first \textit{Chandra}, Karl G. Janksy Ver…
An extensive spectroscopic time-series of three Wolf-Rayet stars. I. The lifetime of large-scale structures in the wind of WR 134
E. J. Aldoretta, N. St-Louis, N. D. Richardson +46
During the summer of 2013, a 4-month spectroscopic campaign took place to observe the variabilities in three Wolf-Rayet stars. The spectroscopic data have been analyzed for WR 134…
