A Chandra view of SPT-CL J0217-5014: a massive galaxy cluster at a cosmic intersection at z=0.53
Dan Hu, Shida Fan, Zhongsheng Yuan +7
Galaxy clusters trace the densest regions of the cosmic web and are crucial laboratories for studying the thermodynamic and chemical evolution of the intracluster medium (ICM). We…
First High-Resolution Spectroscopy of X-ray Absorption Lines in the Obscured State of NGC 5548
Missagh Mehdipour, Gerard A. Kriss, Jelle S. Kaastra +5
Multi-wavelength spectroscopy of NGC 5548 revealed remarkable changes due to presence of an obscuring wind from the accretion disk. This broadened our understanding of obscuration…
Time-dependent photoionization spectroscopy of the Seyfert galaxy NGC 3783
Liyi Gu, Jelle Kaastra, Daniele Rogantini +4
We present an investigation into the spectroscopic properties of non-equilibrium photoionization processes operating in a time-evolving mode. Through a quantitative comparison betw…
Density calculations of NGC 3783 warm absorbers using a time-dependent photoionization model
Chen Li, Jelle S. Kaastra, Liyi Gu +1
Outflowing wind as one type of AGN feedback, which involves noncollimated ionized winds prevalent in Seyfert-1 AGNs, impacts their host galaxy by carrying kinetic energy outwards.…
Charge exchange in X-ray astrophysics
Liyi Gu, Chintan Shah
Charge exchange is an atomic process that primarily occurs at interfaces between the neutral and ionized gas. The study of the process has been carried out on three levels: the the…
XMM-Newton view of the shock heating in an early merging cluster, CIZA J1358.94750
Y. Omiya, K. Nakazawa, K. Matsushita +10
CIZA J1358.9-4750 is a nearby galaxy cluster in the early phase of a major merger. The two-dimensional temperature map using XMM-Newton EPIC-PN observation confirms the existence o…
