  • LMC X-3 formation history

    We have endeavoured to understand the formation and evolution of the black hole (BH) X-ray binary LMC X-3. We estimated the properties of the system at four evolutionary stages:...
  • Ionizing and heating power of ULXs

    While there is now a consensus that X-ray binaries (XRBs) are the dominant X-ray sources in the early Universe and play a significant role during the epoch of heating of the...
  • Neutron-star kicks in HMXBs with Gaia EDR3

    All neutron star progenitors in neutron-star High-Mass X-ray Binaries (NS HMXBs) undergo a supernova event that may lead to a significant natal kick impacting the motion of the...
  • Outbursts of GX339-4 at 5.5 and 9.0GHz fluxes

    Galactic black hole binaries produce powerful outflows which emit over almost the entire electromagnetic spectrum. Here, we report the first detection with the Herschel...
  • Cataclysmic Binaries, LMXBs, and related objects

    (no description available) Cone search capability for table B/cb/cbdata (Catalogue of Cataclysmic Binaries) Cone search capability for table B/cb/lmxbdata (Catalogue of Low-Mass...
  • Pre-eclipse dip of Her X-1

    We report on a pre-eclipse dip of the X-ray binary pulsar Her X-1 observed by the Rossi X-ray Timing Explorer (RXTE) in 1996 July. The energy spectra in the 3-18keV range can be...
  • Lindroos binary systems X-ray emission

    We present a study of the X-ray emission from binary systems extracted from the Lindroos catalogue (Lindroos, 1986A&A...156..223L) based on the ROSAT All-Sky survey as well...
  • Comptonization and reflection in GRS 1915+105

    We present a comprehensive X-ray study of four years of pointed RXTE observations of GRS 1915+105 in the {chi}-state. We interpret the behavior of the hard power law tail...
  • X-ray power spectra of Cygnus X-1

    We present the long term evolution of the timing properties of the black hole candidate Cygnus X-1 in the 0.002-128 Hz frequency range as monitored from 1998 to 2001 with the...
  • Catalog of Ultraluminous X-ray sources

    We present a catalogue of ultraluminous X-ray sources (ULXs) in external galaxies. The aim of this catalogue is to provide easy access to the properties of ULXs, their possible...
  • HeI & HeII radial velocities of Sk 160/SMC X-1

    We present new optical spectroscopy of the eclipsing binary pulsar Sk 160/SMC X-1. From the He I absorption lines, taking heating corrections into account, we determine the...
  • High-mass X-ray binaries in the Magellanic Clouds

    We present a catalogue of high-mass X-ray binaries in the Magellanic Clouds. The catalogue lists source name(s), coordinates, apparent magnitudes, orbital parameters, and X-ray...
  • Cyg X-1 Spectral Evolution 1999-2004

    Continuing the observational campaign initiated by our group, we present the long term spectral evolution of the Galactic black hole candidate Cygnus X-1 in the X-rays and at...
  • Catalogue of Galactic high-mass X-ray binaries

    We present a new edition of the catalogue of high-mass X-ray binaries in the Galaxy. The catalogue contains source name(s), coordinates, finding chart, X-ray luminosity, system...
  • Counterparts to massive X-ray binaries

    The X-ray and gamma-ray observatory INTEGRAL has discovered large numbers of new hard X-ray sources, many of which are believed to be high mass X-ray binaries. However, for a...
  • BVRIJHK light curves of 4U 0115+63/V635 Cas

    4U 0115+63 is one of the most active and best studied Be/X-ray transients. Previous studies of 4U 0115+63 have led to the suggestion that 4U 0115+63 undergoes relatively fast...
  • Sources detected by ISGRI

    In its first 4 years of observing the sky above 20keV, INTEGRAL-ISGRI has detected 500 sources, around half of which are new or unknown at these energies. Follow-up observations...
  • LMXBs in the bulge of M31

    We explore the population of X-ray point sources in the bulge of M31 to contrast properties of various subpopulations, such as persistent and transient sources and primordial...
  • Catalogue of Galactic low-mass X-ray binaries

    We present a new edition of the catalogue of the low-mass X-ray binaries in the Galaxy and the Magellanic Clouds. The catalogue contains source name(s), coordinates, finding...
  • Spectroscopy of 7 INTEGRAL X-ray sources

    The INTEGRAL hard X-ray observatory has revealed an emerging population of highly obscured X-ray binary systems through multi-wavelength observations. Previous studies have...
