Exploring the Nature of Weak Chandra Sources near the Galactic Centre
R. M. Bandyopadhyay, K. M. Blundell, Ph. Podsiadlowski +5
We present early results from the first IR imaging of the weak X-ray sources discovered in a recent Chandra survey towards the Galactic Centre. From our VLT observations we will id…
The Hard Truth about Some "Soft" X-ray Transients
R. M. Bandyopadhyay, C. Brocksopp, R. P. Fender
We have accumulated multiwavelength lightcurves for eight black hole X-ray binaries which have been observed to enter a supposed ``soft X-ray transient'' outburst, but which in fac…
Eclipse Timings of the Low Mass X-ray Binary EXO0748-676 III. An Apparent Orbital Period Glitch Observed with USA and RXTE
M. T. Wolff, P. Hertz, K. S. Wood +2
We present 7 eclipse timings of the low mass X-ray binary EXO0748-676 obtained with the USA experiment during 1999-2000 as well as 122 eclipse timings obtained with RXTE during 199…
The USA X-ray Timing Experiment
P. S. Ray, K. S. Wood, G. Fritz +21
The USA Experiment is a new X-ray timing experiment with large collecting area and microsecond time resolution capable of conducting a broad program of studies of galactic X-ray bi…
Infrared spectroscopy of V616 Mon (=A0620--00): the accretion disc contamination
T. Shahbaz, R. M. Bandyopadhyay, P. A. Charles
We have obtained for the first time -band infrared spectra of the soft X-ray transient V616 Mon (=A0620--00). We determine the 2-sigma upper limit to the fraction of light arisi…
