Context. Low-mass X-ray binaries (LMXBs) are a natural workbench to study accretion disk phenomena and optimal background sources to measure elemental abundances in the interstellar medium (ISM). In high-resolution XMM-Newton spectra, the LMXB SAX J1808.4−3658 in the past showed a neon column density significantly higher than expected given its small distance, presumably due to additional absorption from a neon-rich circumstellar medium (CSM). Aims. It is possible to detect intrinsic absorption… 
From ultraluminous X-ray sources to ultraluminous supersoft sources: NGC 55 ULX, the missing link
In recent work with high-resolution grating spectrometers (RGS) aboard XMM-Newton Pinto et al. (2016) have discovered that two bright and archetypal ultraluminous X-ray sources (ULXs) have strong
Radio and X-ray monitoring of the accreting millisecond X-ray pulsar IGR J17591−2342 in outburst
IGR J17591−2342 is a new accreting millisecond X-ray pulsar that was recently discovered in outburst in 2018. Early observations revealed that the source’s radio emission is brighter than that of
An Ultra-Fast X-ray Disk Wind in the Neutron Star Binary GX 340+0
We present a spectral analysis of a brief Chandra/HETG observation of the neutron star low-mass X-ray binary GX~340+0. The high-resolution spectrum reveals evidence of ionized absorption in the Fe K
XMM-Newton Survey of Local O vii Absorption Lines in the Spectra of Galactic X-Ray Sources
The detection of highly ionized metal absorption lines in the X-ray spectra of the Galactic X-ray binaries (XRBs) implies the distribution of hot gas along the sightline toward the background
X-ray detection of warm ionized matter in the Galactic halo
We report on a systematic investigation of the cold and mildly ionized gaseous baryonic metal components of our Galaxy, through the analysis of high resolution Chandra and XMM-Newton spectra of two
Accretion Disks and Coronae in the X-Ray Flashlight
Plasma accreted onto the surface of a neutron star can ignite due to unstable thermonuclear burning and produce a bright flash of X-ray emission called a Type-I X-ray burst. Such events are very
Disc–jet coupling in low-luminosity accreting neutron stars
In outburst, neutron star X-ray binaries produce less powerful jets thanblack holes at a given X-ray luminosity. This has made them moredifficult to study as they fade towards quiescence. To explore
Complex Rotated Relativistic Configuration-Interaction Calculations of 1s2l2l ' States in O5+ Ion
Relativistic calculations of the energies and Auger widths of the lowest autoionizing states of lithium-like oxygen are performed. All leading corrections to the energy, including the contribution of
