Journal ArticleDOI
High-resolution X-ray observations of the Cassiopeia A supernova remnant with the Einstein Observatory
TL;DR: In this paper, the mass of the expanding shell due to the interaction of the blast wave and the ambient medium is determined, indicating that Cas A is probably not in the free expansion phase, but has not yet reached the adiabatic phase of expansion.
Journal ArticleDOI
An improved approach to measuring H_0 using X-ray and SZ observations of galaxy clusters
TL;DR: In this article, an improved method for predicting the Sunyaev-Zeldovich (SZ) effect in galaxy clusters from spatially-resolved, spectroscopic X-ray data is presented.
Journal ArticleDOI

TL;DR: In this paper, Chandra observations of the bright ultraluminous X-ray (ULX) source in NGC 3921 were reported, and a Chandra position of the ULX accurate to 0.7 at 90% confidence was provided.
Journal ArticleDOI
Fe K\alpha emission from photoionized slabs: the impact of the iron abundance
TL;DR: In this paper, the equivalent width (EW) of the Fe K line depends on the iron abundance of the illuminated gas and its ionization state, two variables subject to significant cosmic scatter.
