Near Infrared Observations of Galactic Black Hole Candidates
S. Chaty, I. F. Mirabel, P. Goldoni +4
We report on several European Southern Observatory (ESO) near-infrared (NIR) observational campaigns aimed at understanding the nature of galactic black hole candidates. Our result…
The Evolving Accretion Disc in the Black Hole X-ray Transient XTE J1859+226
R. I. Hynes, C. A. Haswell, S. Chaty +2
We present HST, RXTE, and UKIRT observations of the broad band spectra of the black hole X-ray transient XTE J1859+226 during the decline from its 1999-2000 outburst. Our UV spectr…
A search for radio emission from Galactic supersoft X-ray sources
R. N. Ogley, S. Chaty, M. Crocker +5
We have made a deep search for radio emission from all the northern hemisphere supersoft X-ray sources using the VLA and MERLIN telescopes, at 5 and 8.4 GHz. Three previously undet…
Characterising anomalous transport in accretion disks from X-ray observations
J. Greenhough, S. C. Chapman, S. Chaty +2
Whilst direct observations of internal transport in accretion disks are not yet possible, measurement of the energy emitted from accreting astrophysical systems can provide useful…
Complete and Simultaneous Spectral Observations of the Black-Hole X-ray Nova XTE J1118+480
J. E. McClintock, C. A. Haswell, M. R. Garcia +13
The X-ray nova XTE J1118+480 suffers minimal extinction (b = 62 degrees) and therefore represents an outstanding opportunity for multiwavelength studies. Hynes et al. (2000) conduc…
On the nature of the microquasar V4641 Sagittari
S. Chaty, I. F Mirabel, J. Marti +1
We present photometric and spectroscopic optical and near-infrared (NIR) observations (Based on observations collected at the European Southern Observatory, Chile (ESO ID 63.H-0493…
