Chemical abundances in the outskirts of nearby galaxy groups measured with joint Suzaku and Chandra observations
Arnab Sarkar, Yuanyuan Su, Nhut Truong +5
We report results from deep Suzaku and mostly snapshot Chandra observations of four nearby galaxy groups: MKW4, Antlia, RXJ1159+5531, and ESO3060170. Their peak temperatures vary o…
AGN feedback duty cycle in Planck SZ selected clusters using Chandra observations
V. Olivares, Y. Su, P. Nulsen +5
We present a systematic study of X-ray cavities using archival Chandra observations of nearby galaxy clusters selected by their Sunyaev-Zel'dovich (SZ) signature in the Planck surv…
Discovery of a pre-merger shock in an intercluster filament in Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +11
We report the first unambiguous detection of an axial merger shock in the early-stage merging cluster Abell 98 using deep (227 ks) Chandra observations. The shock is about 420 kpc…
X-ray spectroscopy in the microcalorimeter era 4: Optical depth effects on the soft X-rays studied with CLOUDY
Priyanka Chakraborty, Gary Ferland, Marios Chatzikos +4
In this paper, we discuss atomic processes modifying the soft X-ray spectra in from optical depth effects like photoelectric absorption and electron scattering suppressing the soft…
Independent Evidence for earlier formation epochs of fossil groups of galaxies through the intracluster light: the case for RX J100742.53+380046.6
Renato A. Dupke, Yolanda Jimenez-teja, Yuanyuan Su +9
Fossil groups (FG) of galaxies still present a puzzle to theories of structure formation. Despite the low number of bright galaxies, they have relatively high velocity dispersions…
Deep Chandra observations of NGC 1404: cluster plasma physics revealed by an infalling early-type galaxy
Yuanyuan Su, Ralph P. Kraft, Elke Roediger +6
The intracluster medium (ICM), as a magnetized and highly ionized fluid, provides an ideal laboratory to study plasma physics under extreme conditions that cannot yet be achieved o…
