A deep XMM-Newton survey of M 31

H. Stiele, W. Pietsch, F. Haberl

The deep homogeneous survey of the large Local-Group spiral galaxy M 31 is a milestone project for X-ray astronomy, as it allows a detailed X-ray inventory of an archetypal low-sta…

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…
