Abstract:
Although numerous archival XMM-Newton observations existed towards the
Small Magellanic Cloud (SMC) before 2009, only a fraction of the whole
galaxy had been covered. Between May 2009 and March 2010, we carried
out an XMM-Newton survey of the SMC, to ensure a complete coverage of
both its bar and wing. Thirty-three observations of 30 different
fields with a total exposure of about one Ms filled the previously
missing parts. We systematically processed all available SMC data from
the European Photon Imaging Camera. After rejecting observations with
very high background, we included 53 archival and the 33 survey
observations. We produced images in five different energy bands. We
applied astrometric boresight corrections using secure identifications
of X-ray sources and combined all the images to produce a mosaic
covering the main body of the SMC. We present an overview of the
XMM-Newton observations, describe their analysis, and summarise our
first results, which will be presented in detail in follow-up papers.
Here, we mainly focus on extended X-ray sources, such as supernova
remnants (SNRs) and clusters of galaxies, that are seen in our X-ray
images. Our XMM-Newton survey represents the deepest complete survey
of the SMC in the 0.15-12.0keV X-ray band. We propose three new SNRs
that have low surface brightnesses of a few
10-14erg/s/cm2/arcmin2 and large extents. In addition, several
known remnants appear larger than previously measured at either X-rays
or other wavelengths extending the size distribution of SMC SNRs to
larger values.
Description:
X-ray mosaic images from combined EPIC pn and MOS data of the SMC
region centred at RA=01:00:30, DE=-72:28:00 (J2000). The three images
were produced in the three energy bands 0.2-1.0keV, 1.0-2.0keV, and
2.0-4.5keV. The images are exposure-corrected and for EPIC pn
out-of-time event subtracted, but not detector-background subtracted
and not vignetting-corrected.
