Distribution of High Mass X-ray Binaries in the Milky Way
  The INTEGRAL satellite, observing the sky at high energy, has quadrupled the
number of supergiant X-ray Binaries known in the Galaxy and has revealed new
populations of previously hidden High Mass X-ray Binaries. These observations
raise new questions about the formation and evolution of these sources. The
number of detected sources is now high enough to allow us to carry out a
statistical analysis of the distribution of HMXBs in the Milky Way. We derive
the distance of each HMXB using a Spectral Energy Distribution fitting
procedure, and we examine the correlation with the distribution of star forming
complexes (SFCs) in the Galaxy. We show that HMXBs are clustered with SFCs,
with a typical size of 0.3 kpc and a characteristic distance between clusters
of 1.7 kpc.
