Accretion disk wind of Hercules X-1 during the Short High state
P. Kosec, E. Kara, A. C. Fabian +5
Hercules X-1 is a nearly edge-on X-ray binary with a warped, precessing accretion disk, which manifests through a 35-day cycle of alternating High and Low flux states. This disk pr…
Chemical enrichment of ICM within the Ophiuchus cluster I: radial profiles
Efrain Gatuzz, J. S. Sanders, K. Dennerl +6
The analysis of the elemental abundances in galaxy clusters offers valuable insights into the formation and evolution of galaxies. In this study, we explore the chemical enrichment…
Chemical enrichment of ICM within the Centaurus cluster I: radial profiles
Efrain Gatuzz, J. S. Sanders, K. Dennerl +6
We examine deep {\it XMM-Newton} EPIC-pn observations of the Centaurus cluster to study the hot intracluster medium (ICM) and radial metal distributions within such an environment.…
Measuring the hot ICM velocity structure function using XMM-Newton observations
Efrain Gatuzz, R. Mohapatra, C. Federrath +4
It has been shown that the gas velocities within the intracluster medium (ICM) can be measured by applying novel XMM-Newton EPIC-pn energy scale calibration, which uses instrumenta…
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…
Vertical wind structure in an X-ray binary revealed by a precessing accretion disk
P. Kosec, E. Kara, A. C. Fabian +11
The accretion of matter onto black holes and neutron stars often leads to the launching of outflows that can greatly affect the environments surrounding the compact object. In supe…
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…
Chemical enrichment of the ICM within the Virgo cluster I: radial profiles
Efrain Gatuzz, J. Sanders, K. Dennerl +8
We present a detailed analysis of the elemental abundances distribution of the Virgo cluster using {\it XMM-Newton} observations. We included in the analysis a new EPIC-pn energy s…
