Ellipsoidal variables in ASAS-SN catalog
The majority of non-merging stellar mass black holes are discovered by observing high energy emission from accretion processes. Here, we pursue the large, but still mostly... -
IR lines of AGNs accretion disk
Accretion states, which are universally observed in stellar mass black holes in X-ray binaries, might be expected in active galactic nuclei (AGN). This is the case at low... -
The Swift Bulge Survey. first X-ray results
Very faint X-ray transients (VFXTs) are X-ray transients with peak X-ray luminosities (L_X_) of L_X_~<10^36^erg/s, which are not well understood. We carried out a survey of... -
Black hole mass accretion rates for over 750 AGN
Mass accretion rates in dimensionless and physical units, and efficiency factors describing the total radiant luminosity of the disc and the beam power of the outflow are... -
Polarization of LMXB MAXI J1820+070
We describe the first complete polarimetric dataset of the entire outburst of a low-mass black hole X-ray binary system and discuss the constraints for geometry and radiative... -
Radio astrometry of MAXI J1820+070
Using the Very Long Baseline Array and the European Very Long Baseline Interferometry Network, we have made a precise measurement of the radio parallax of the black hole X-ray... -
Effects of metallicity on HMXB formation
The heating of the intergalactic medium in the early, metal-poor Universe may have been partly due to radiation from high-mass X-ray binaries (HMXBs). Previous investigations on... -
Transient black hole X-ray binaries XMM obs.
All observations of Galactic X-ray binaries are affected by absorption from gas and dust in the interstellar medium (ISM) which imprints narrow (line) and broad (photoelectric... -
Spectral evolution of 4U 1543-47 in 2002
We investigate the viscous evolution of the accretion disc in 4U 1543-47, a black hole binary system, during the first 30 d after the peak of the 2002 burst by comparing the... -
Bright HMXBs in THINGS galaxies
Using a spectral analysis of bright Chandra X-ray sources located in 27 nearby galaxies and maps of star-formation rate (SFR) and ISM surface densities for these galaxies, we... -
Sample of faint X-ray pulsators
We report on the discovery of 41 new pulsating sources in the data of the Chandra Advanced CCD Imaging Spectrometer, which is sensitive to X-ray photons in the 0.3-10 keV band.... -
Type II bursts in the Rapid Burster
Type II bursts are thought to arise from instabilities in the accretion flow on to a neutron star in an X-ray binary. Despite having been known for almost 40 years, no model can... -
Black hole binaries quasi-periodic oscillations
We present a systematic study of the orbital inclination effects on black hole transients fast time-variability properties. We have considered all the black hole binaries that... -
Galactic Bulge accreting binaries spectroscopy
We present the identification of optical counterparts to 23 GBS X-ray sources. All sources are classified as accreting binaries according to the emission-line characteristics... -
Swift J1745-26 polarized jet
Swift J1745-26 is an X-ray binary towards the Galactic Centre that was detected when it went into outburst in 2012 September. This source is thought to be one of a growing... -
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... -
GX 339-4 radio/X-ray flux correlation
The existing radio and X-ray flux correlation for Galactic black holes in the hard and quiescent states relies on a sample which is mostly dominated by two sources (GX 339-4 and... -
XTE J1550-564 quasi-periodic oscillations
In this paper, we investigate the energy dependence of the centroid frequency of the low-frequency quasi-periodic oscillations (QPOs; 0.08-20Hz) in XTE J1550-564. We have used... -
X-ray sources in the Phoenix dwarf galaxy
We report on the first X-ray images of the Phoenix dwarf galaxy, taken with XMM-Newton in 2009 July. This Local Group dwarf galaxy shares similarities with the Small Magellanic... -
HMXBs in nearby galaxies
Based on a homogeneous set of X-ray, infrared and ultraviolet observations from Chandra, Spitzer, GALEX and 2MASS archives, we study populations of high-mass X-ray binaries...
