Hidden Cooling Flows IV: More Details on Centaurus and the Efficiency of AGN Feedback in Clusters
A. C. Fabian, G. J. Ferland, J. S. Sanders +7
Cooling flows are common in galaxy clusters which have cool cores. The soft X-ray emission below 1 keV from the flows is mostly absorbed by cold dusty gas within the central coolin…
Consequences of a low-mass, high-pressure, star formation mode in early galaxies
A. C. Fabian, J. S. Sanders, G. J. Ferland +3
High resolution X-ray spectra reveal hidden cooling flows depositing cold gas at the centres of massive nearby early-type galaxies with little sign of normal star formation. Optica…
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…
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…
The cycle of metals in the infalling elliptical galaxy NGC 1404
F. Mernier, N. Werner, Y. Su +6
Hot atmospheres pervading galaxy clusters, groups, and early-type galaxies are rich in metals, produced during epochs and diffused via processes that are still to be determined. Wh…
Measuring sloshing, merging and feedback velocities in the Virgo cluster
Efrain Gatuzz, J. S. Sanders, K. Dennerl +5
We present a detailed analysis of the velocity structure of the Virgo cluster using {\it XMM-Newton} observations. Using a novel technique which uses uses the Cu K instrumental…
