Abstract:
This dissertation presents the analysis of a large and deep XMM-Newton
survey of the second largest Local Group spiral galaxy M 31. The 
survey observations, taken between June 2006 and February 2008, 
together with re-analysed archival observations from June 2000 to July
2004 cover, for the first time, the whole D25-ellipse of M 31 with 
XMM-Newton down to a limiting luminosity of ~10^{35} erg s^-1 in the 
0.2-4.5 keV band. 

The main goal of the thesis is a study of the different source 
populations of M 31 that can be observed in X-rays. Therefore a 
catalogue was created, which contains all 1948 sources detected in the
0.2-12.0 keV range. 961 of these sources were detected in X-rays for 
the first time. Source classification and identification was based on
X-ray hardness ratios, spatial extent of the sources, and by cross 
correlating with catalogues in the X-ray, optical, infrared and radio 
wavelengths. An additional classification criterion was the long-term
temporal variability of the sources in X-rays. This variability allows
us to distinguish between X-ray binaries and active galactic nuclei. 
Furthermore, supernova remnant classifications of previous studies 
that did not use long-term variability as a classification criterion,
could be validated. Including previous Chandra and ROSAT observations
in the long-term variability study allowed me to detect additional
transient or at least highly variable sources, which are good 
candidates for being X-ray binaries.

Fourteen of the 40 supersoft source (SSS) candidates correlated with
optical novae and therefore can be considered the supersoft emission 
of the optical novae. Among them is the first nova/SSS detected in a
globular cluster of M 31. Correlations with previous ROSAT and Chandra
studies revealed that only three SSSsare visible for at least one 
decade. This result underlines the strong long-term variability found
for the class of SSSs. In addition the correlations demonstrated that
strict selection criteria have to be applied to securely select SSSs.

An investigation of the spatial distribution of the 25 supernova 
remnants (SNRs) and 37 SNR candidates showed that many of these 
sources are consistent with the location of the 10 kpc dust ring and
other star forming regions in M 31. This connection between SNRs and
star forming regions implies that most of the remnants are from 
type II supernovae. 

The brightest sources of M 31 belong to the class of X-ray binaries 
(XRBs). Ten low mass XRBs (LMXBs) and 26 LMXB candidates were 
identified based on their temporal variability. In addition 36 LMXBs 
and 17 LMXB candidates were identified due to correlations with 
globular clusters and globular cluster candidates. From the LMXBs 
located in globular clusters one is a black hole candidate and another
a neutron star candidate. From optical and X-ray colour-colour 
diagrams, possible high mass XRB (HMXB) candidates were selected. 
Two of these candidates have an X-ray spectrum as is expected for an
HMXB containing a neutron star primary.

To investigate the logN-logS relations of sources in the field of 
M 31, a catalogue of sources detected in the 2.0-10.0 keV energy range
was created. The slope of the logN-logS relation for the whole galaxy
is consistent with the expectation for spiral galaxies (Colbert et al.
2004). Subtracting the background logN-logS relation, the region 
beyond the D25-ellipse still contains about 13 sources/deg^2 of M 31
with fluxes above the completeness limit of ~3.2 10^{-14} erg cm^-2 
s^-1 (2.3 10^36 erg s^-1 at the distance of M 31). The radial 
dependence of the source distribution in M 31's disc can be well 
fitted with an exponential profile, for limiting fluxes of ~3.2 
10^{-14} erg cm^-2 s^-1 and 10^{-13} erg cm^-2 s^-1 (7.3 10^36 erg 
s^-1). About 60% of all sources with fluxes above 3.2 10^{-14} erg 
cm^-2 s^-1 are background sources. While the contribution of 
background sources lies at ~20% in the inner disc region, the fraction
increases to >80% in the outer areas of M 31. For the dust ring 
region, the slope of the logN-logS relation as well as the number of
sources and their dependence on the star forming rate were consistent
with the universal logN-logS relation predicted from theoretical 
considerations of HMXBs (Grimm et al. 2003). These findings propose 
that the dust ring region contains a population of HMXBs.

A comparison of the number of X-ray binaries (XRBs) obtained from the 
logN-logS study to the ones listed in the source catalogue showed that
many XRBs detected in the logN-logS study with fluxes between 10^{-13}
erg cm^-2 s^-1 and 3.2 10^{-14} erg cm^-2 s^-1, or (independent from
the flux) those XRBs located in the inner disc of M 31, remain without
XRB classification in the source catalogue. 

The results presented in this thesis gave us deeper insights in the 
properties of the population of X-ray sources in M 31. Nevertheless,
about 65% of all sources detected in the field of M 31 can be 
classified as ``hard" sources only, i.e. it is not possible to decide
whether these sources are X-ray binaries or Crab-like supernova 
remnants in M 31, or active galactic nuclei. Deeper observations in 
the X-ray and at other wavelengths are needed to classify these 
sources.
