TL;DR: In this paper, the authors investigated the dependence of the low-mass X-ray binary population in early-type galaxies on stellar age and found that older galaxies tend to possess about 50% more LMXBs (per unit stellar mass) than the younger ones.

TL;DR: In this article, the authors analyzed the gas temperature maps created from the Chandra archive data, revealing the prevailing existence of temperature substructures on ~100 h −1 70 kpc scales in the central regions of nine intermediate-redshift (z ≈ 0.1) galaxy clusters, which resemble those found in the Virgo and Coma Clusters.

TL;DR: In this article, a detailed analysis of the high-quality Chandra, XMM-Newton, and Suzaku data of the X-ray bright cluster of galaxies A1795 was performed, and the authors reported clear evidence for a two-phase intracluster medium (ICM) structure, which consists of a cool (with a temperature T-c approximate to 2.0-2.2 keV) and a hot (T-h approximate to 5.7 keV).

TL;DR: In this paper, the authors used a Comptonized blackbody model with relatively high (2.0) optical depths, plus an additional softer optically-thick component, to reproduce the spectrum of the neutron-star low-mass X-ray binary Aquila X-1.

TL;DR: In this paper, Chandra, XMM-Newton, and Suzaku data of the X-ray bright cluster of galaxies Abell 1795 were used to detect a two-phase ICM structure, which consists of a cool (with a temperature T = 2.0-2.2 keV) and a hot (T = 5.0 -5.7 keV).
