New insights into ultraluminous X-ray sources from deep XMM-Newton observations
T. P. Roberts, A. -M. Stobbart, M. R. Goad +4
The controversy over whether ultraluminous X-ray sources (ULXs) contain a new intermediate-mass class of black holes (IMBHs) remains unresolved. We present new analyses of the deep…
ULTRACAM photometry of the eclipsing cataclysmic variables GY Cnc, IR Com and HT Cas
W. J. Feline, V. S. Dhillon, T. R. Marsh +2
We present high-speed, three-colour photometry of the eclipsing cataclysmic variables GY Cnc, IR Com and HT Cas. We find that the sharp eclipses in GY Cnc and IR Com are due to ecl…
Zeeman tomography of magnetic white dwarfs II. The quadrupole-dominated magnetic field of HE 1045-0908
F. Euchner, K. Reinsch, S. Jordan +2
We report time-resolved optical flux and circular polarization spectroscopy of the magnetic DA white dwarf HE 1045-0908 obtained with FORS1 at the ESO VLT. Considering published re…
ULTRACAM observations of the black hole X-ray transient XTE J1118+480 in quiescence
T. Shahbaz, V. S. Dhillon, T. R. Marsh +5
We present high time-resolution multicolour observations of the quiescent soft X-ray transient XTE J1118+480 obtained with ULTRACAM. Superimposed on the double-humped continuum g'…
Probing the outer edge of an accretion disk: A Her X-1 turn-on observed with RXTE
M. Kuster, J. Wilms, R. Staubert +4
We present the analysis of Rossi X-ray Timing Explorer (RXTE) observations of the turn-on phase of a 35 day cycle of the X-ray binary Her X-1. During the early phases of the turn-o…
XMM-Newton observations of AM CVn binaries
Gavin Ramsay, Pasi Hakala, Tom Marsh +3
We present the results of XMM-Newton observations of four AM CVn systems -- AM CVn, CR Boo, HP Lib and GP Com. Their light curves show very different characteristics. The X-ray lig…
