Context. Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs)
in the central region of our neighbouring galaxy M 31. Aims. We performed a dedicated …

Aims. The largest Local Group spiral galaxy, M 31, has been completely imaged for the first
time, obtaining a luminosity lower limit~ 10 35 erg s-1 in the 0.2–4.5 keV band. Our XMM …

Context. Optical novae have recently been identified as the major class of supersoft X-ray
sources in M 31 based on ROSAT and early XMM-Newton and Chandra observations. Aims …

Very faint X-ray binaries (VFXBs), defined as having peak luminosities LX of 1034–1036 erg
s− 1, have been uncovered in significant numbers, but remain poorly understood. We …

Aims. We explore the population of X-ray point sources in the bulge of M 31 to contrast
properties of various subpopulations, such as persistent and transient sources and …

Context. Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs)
in the central region of the galaxy M 31. Aims. We performed a dedicated monitoring of the M …

ABSTRACT A recent analysis of supernova (SN) 2002bj revealed that it was an apparently
unique type Ib SN. It showed a high peak luminosity, with absolute magnitude MR∼− 18.5 …

Context. Classical novae (CNe) have recently been reported to represent the major class of
supersoft X-ray sources (SSSs) in the central region of our neighbour galaxy M 31. Aims. We …

We confirm our earlier tentative detection of M31* in X-rays and measure its light curve and
spectrum. Observations in 2004–2005 find M31* rather quiescent in the X-ray and radio …

Context. We present the analysis of supernova remnants (SNRs) and candidates in M 31
identified in the XMM-Newton large programme survey of M 31. Supernova remnants are …
