Spectral changes during dipping in low-mass X-ray binaries due to highly-ionized absorbers
X-ray observations have revealed that many microquasars and low-mass X-ray binaries (LMXBs) exhibit narrow absorption features identified with resonant absorption from Fe XXV and Fe XXVI and otherExpand

Correlated X-ray Spectral and Timing Behavior of the Black Hole Candidate
We present an analysis of data of the black hole candidate and X-ray transient XTE J1550-564, taken with the Rossi X-Ray Timing Explorer between 1998 November 22 and 1999 May 20. During this periodExpand

Gravitationally redshifted absorption lines in the X-ray burst spectra of a neutron star
The fundamental properties of neutron stars provide a direct test of the equation of state of cold nuclear matter, a relationship between pressure and density that is determined by the physics of theExpand

Constraining supernova models using the hot gas in clusters of galaxies
Context: The hot X-ray emitting gas in clusters of galaxies is a very large repository of metals produced by supernovae. During the evolution of clusters, billions of supernovae eject their materialExpand

The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of two key questions inExpand

An Unstable Central Disk in the Superluminal Black Hole X-Ray Binary GRS 1915+105
TLDR
We have analyzed the X-ray spectra of the microquasar GRS 1915+105, as observed with the Proportional Counter Array on the Rossi X-Ray Timing Explorer, during periods of stable weak emission, outbursts, and rapid flaring. Expand

A highly-ionized absorber in the X-ray binary 4U 1323-62: A new explanation for the dipping phenomenon
We report the detection of narrow $\ion{Fe}{xxv}$ and $\ion{Fe}{xxvi}$  X-ray absorption lines at $6.68 \pm 0.04$ keV and $6.97 \pm 0.05$ keV in the persistent emission of the dipping low-mass X-rayExpand

XTE J1701–462 AND ITS IMPLICATIONS FOR THE NATURE OF SUBCLASSES IN LOW-MAGNETIC-FIELD NEUTRON STAR LOW-MASS X-RAY BINARIES
We report on an analysis of Rossi X-Ray Timing Explorer data of the transient neutron star low-mass X-ray binary (NS-LMXB) XTE J1701-462, obtained during its 2006-2007 outburst. The X-ray propertiesExpand
