The hard X-ray behavior of Aql X-1 during type-I bursts
, 2013 We report the discovery of an anti-correlation between the soft and the hard X-ray lightcurves of the X-ray binary Aql X-1 when bursting. This behavior may indicate that the corona is cooled by the soft X-ray shower fed by the type-I X-ray bursts, and ...

Detection of Multiple X-Ray Quasi-periodic Oscillations in IGR J19294+1816 with Insight-HXMT
The Astrophysical JournalWe report the timing results with Insight-HXMT observations of X-ray binary IGR J19294+1816 during its 2019 type I outburst at the decline phase shortly following its peak.

The X-ray binary population in M33: II. X-ray spectra and variability
, 2007 In this paper we investigate the X-ray spectra and X-ray spectral variability of compact X-ray sources for 3 Chandra observations of the Local Group galaxy M33. The observations are centered on the nucleus and the star forming region NGC 604.

Massive X-ray binaries and the X-ray background [PDF]
The 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1999 In this calculation we estimate the contribution of massive X-ray binaries to the hard X-ray background (XRB). Traditionally, due to their short life-times, MXRBs were thought not to be significant contributors to the XRB. However, given the recent progress in the observational determination of the global star-formation rate as a function of redshift ...

Investigating the Ultracompact X-Ray Binary Candidate SLX 1735-269 with NICER and NuSTAR
The Astrophysical JournalWe present two simultaneous NICER and NuSTAR observations of the ultracompact X-ray binary (UCXB) candidate SLX 1735−269 while the source was in two different spectral states. Using various reflection modeling techniques, we find that xillverCO , a model
