The Spatial and Emission Properties of the Large [O III] Emission Nebula Near M31
Robert A. Fesen, Stefan Kimeswenger, J. Michael Shull +8
Drechsler et al. (2023) reported the unexpected discovery of a 1.5 degree long [O III] emission nebula 1.2 degrees southeast of the M31 nucleus. Here we present additional images o…
Hidden Cooling Flows in Clusters of Galaxies III: Accretion onto the Central Black Hole
A. C. Fabian, J. S. Sanders, G. J. Ferland +3
Recently, we have uncovered Hidden Cooling Flows (HCF) in the X-ray spectra of the central Brightest Galaxies of 11 clusters, 1 group and 2 elliptical galaxies. Here we report such…
A deep dive: Chandra observations of the NGC 4839 group falling into the Coma cluster
M. S. Mirakhor, S. A. Walker, J. Runge
Cosmological simulations of structure formation predict that galaxy clusters continue to grow and evolve through ongoing mergers with group-scale systems. During these merging even…
Measuring the ICM velocity structure in the Ophiuchus cluster
Efrain Gatuzz, J. S. Sanders, K. Dennerl +8
We have found evidence of bulk velocities following active galactic nucleus (AGN) bubbles in the Virgo cluster and galaxy motions in the Centaurus cluster. In order to increase the…
Hidden Cooling Flows in Clusters of Galaxies II: A Wider Sample
A. C. Fabian, J. S. Sanders, G. J. Ferland +3
We have recently uncovered Hidden Cooling Flows (HCFs) in the XMM RGS spectra of 3 clusters of galaxies, Centaurus, Perseus and A1835. Here we search for them in a wider sample of…
Hidden Cooling Flows in Clusters of Galaxies
A. C. Fabian, G. J. Ferland, J. S. Sanders +3
The radiative cooling time of the hot gas at the centres of cool cores in clusters of galaxies drops down to 10 million years and below. The observed mass cooling rate of such gas…
