X-ray monitoring of optical novae in M31 from July 2004 to February 2005
W. Pietsch, F. Haberl, G. Sala +9
Optical novae have recently been identified as the major class of supersoft X-ray sources in M31 based on ROSAT and early XMM-Newton and Chandra observations. This paper reports on…
Optical novae: the major class of supersoft X-ray sources in M 31
W. Pietsch, J. Fliri, M. J. Freyberg +4
We searched for X-ray counterparts of optical novae detected in M 31 and M 33. We combined an optical nova catalogue from the WeCAPP survey with optical novae reported in the liter…
Integral field spectroscopy of the ultraluminous X-ray source Holmberg II X-1
I. Lehmann, T. Becker, S. Fabrika +10
We present optical integral field observations of the H II region containing the ultraluminous X-ray source Holmberg II X-1. We confirm the existence of an X-ray ionized nebula as…
The rotational broadening and the mass of the donor star of GRS 1915+105
E. T. Harlaftis, J. Greiner
The binary parameters of the microquasar GRS 1915+105 have been determined by the detection of Doppler-shifted 12CO and 13CO lines in its K-band spectrum (Greiner et al., 2001, Nat…
A XMM-Newton observation of Nova LMC 1995, a bright supersoft X-ray source
Marina Orio, Wouter Hartmann, Martin Still +1
Nova LMC 1995, previously detected during 1995-1998 with ROSAT, was observed again as a luminous supersoft X-ray source with XMM-Newton in December of 2000. This nova offers the po…
The 590 days long term periodicity of the microquasar GRS 1915+105
A. Rau, J. Greiner, M. L. McCollough
We report on the discovery of a 590 days long term periodicity in the hard X-ray component of the microquasar \grs found from a comprehensive study of more than four years of {\it…
