Relationships Between Stellar Velocity Dispersion and the Atmospheres of Early-Type Galaxies
R. L. S. Frisbie, M. Donahue, G. M. Voit +3
The Voit et al. (2020) black hole feedback valve model predicts relationships between stellar velocity dispersion and atmospheric structure among massive early-type galaxies. In th…
Properties of the Hot Ambient Medium of Early-type Galaxies Hosting Powerful Radio Sources
Rachel L. S. Frisbie, Megan Donahue, G. Mark Voit +6
We present an archival analysis of Chandra X-ray observations for twelve nearby early-type galaxies hosting radio sources with radio power at 1.4…
X-ray Signatures of Black Hole Feedback: Hot Galactic Atmospheres in IllustrisTNG and X-ray Observations
Nhut Truong, Annalisa Pillepich, Norbert Werner +6
Hot gaseous atmospheres that permeate galaxies and extend far beyond their stellar distribution, where they are commonly referred to as the circumgalactic medium (CGM), imprint imp…
Correlations between supermassive black holes, hot atmospheres, and the total masses of early type galaxies
K. Lakhchaura, N. Truong, N. Werner
We present a study of relations between the masses of the central supermassive black holes (SMBHs) and the atmospheric gas temperatures and luminosities measured within a range of…
Powerful AGN jets and unbalanced cooling in the hot atmosphere of IC 4296
R. Grossová, N. Werner, K. Rajpurohit +13
We present new Karl G. Jansky Very Large Array (VLA, 1.5 GHz) radio data for the giant elliptical galaxy IC 4296, supported by archival radio, X-ray (Chandra, XMM-Newton) and optic…
Possible depletion of metals into dust grains in the core of the Centaurus cluster of galaxies
K. Lakhchaura, F. Mernier, N. Werner
We present azimuthally averaged metal abundance profiles from a full, comprehensive, and conservative re-analysis of the deep (800 ks total net exposure) \textit{Chandra}/ACI…
Cooling in the X-ray halo of the rotating, massive early-type galaxy NGC 7049
A. Juráňová, N. Werner, M. Gaspari +9
The relative importance of the physical processes shaping the thermodynamics of the hot gas permeating rotating, massive early-type galaxies is expected to be different from that i…
Decoding X-ray observations from centres of galaxy clusters using MCMC
Kiran Lakhchaura, Tarun Deep Saini, Prateek Sharma
We correct for the use of electron densities instead of total gas density in the pressure fits which were used to derive the local free-fall times (t) in the original pa…
Dynamics of ten clusters of galaxies with substructures
Kiran Lakhchaura, K. P. Singh
We present a detailed Chandra study of a sample of ten clusters of galaxies selected based on the presence of substructures in their optical images. The X-ray surface brightness ma…
