Abstract:
We present the global X-ray properties of the point source population
in the grand-design spiral galaxy M101, as seen with XMM-Newton. 108
X-ray sources are detected within the D25 ellipse of M101, of which
∼24 are estimated to be background galaxies. Multiwavelength
cross-correlations show that 20 sources are coincident with H II
regions and/or supernova remnants (SNRs), seven have
identified/candidate background galaxy counterparts, six are
coincident with foreground stars and one has a radio counterpart.
Description:
M101 was observed with XMM-Newton for 42.8ks on 2002 June 4
(Obs ID 0104260101). The EPIC MOS-1, MOS-2 and PN cameras were
operated with medium filters in 'Prime Full Window' mode, which
utilizes the full ∼30-arcmin field of view of XMM-Newton, covering the
entire D25 ellipse of M101.
