We report on several European Southern Observatory (ESO) near-infrared (NIR) observational campaigns aimed at understanding the nature of Galactic black hole candidates. Our results, including NIR photometry of the sources GRO J1655−40, GRS 1739−278, GRS 1716−249, GRS 1121−68 and GX 339−4, show that all the sources but GRO J1655−40 are consistent with low-mass stars as the companion star of the binary system. By locating the counterparts on a colour–magnitude diagram (CMD), we better…

We present a detailed spectral analysis of XMM-Newton and NuSTAR observations of the accreting transient black hole GRS 1739-278 during a very faint low hard state at ~0.02% of the Eddington
Optical and near-infrared spectroscopy of the black hole GX 339−4 – I. A focus on the continuum in the low/hard and high/soft states
The microquasar GX 339−4, known to exhibit powerful compact jets that dominate its radio to near-infrared emission, entered an outburst in 2010 for the fifth time in about 15 yr. An extensive radio

During the last ~50 years, the population of black hole candidates in X-ray binaries has increased considerably with 59 Galactic objects detected in transient low-mass X-ray binaries, plus a few in
Quiescent NIR and optical counterparts to candidate black hole X-ray binaries
We present near-infrared and optical imaging of 15 candidate black hole X-ray binaries. In addition to quiescent observations for all sources, we also observed two of these sources (IGR J17451−3022
NEAR-INFRARED SYNCHROTRON EMISSION FROM THE COMPACT JET OF GX 339 4
We have compiled contemporaneous broadband observations of the black hole candidate X-ray binary GX 339-4 when in the low/hard X-ray state in 1981 and 1997. The data clearly reveal the presence of

Measuring the Motion of the Black Hole in GRO J1655-40
We report optical spectroscopic observations of the low-mass X-ray binary GRO J1655-40 during outbursts in 1994 August-September and in 1996 June. The spectra show emission and absorption lines from
The optical counterpart of the superluminal source GRO J1655 – 40
THE accretion of gas from a companion star onto a compact object, such as a neutron star or black hole, can release large amounts of energy. Episodic accretion is generally thought to explain

We report photometric and spectroscopic observations of the black hole binary GRO J1655-40 in complete quiescence. In contrast to the 1995 photometry, the light curves from 1996 are almost completely

Using CGS4 on UKIRT, we have obtained 2.00–2.45 μ m infrared spectra of a number of low-mass X-ray binaries including Sco X-1, Sco X-2 and GX1 3+1. Sco X-1 shows emission lines only, supporting our
Evidence for a black hole in the X-ray nova Muscae 1991
X-RAY novae form a subclass of low-mass X-ray binaries, which typically consist of a neutron star accreting material from a low-mass, late-type companion. In a few cases, however—notably A0620–00
