Identification campaign of supernova remnant candidates in the Milky Way

There are 274 supernova remnants (SNRs) have been identified in the Milky Way.Most SNRs are discovered in radio surveys. In view of various selection effects,the current sample of SNRs is clearly incomplete. ROSAT allsky survey data haveprovided another window to search for SNRs. We have chosen some bright andpromising SNR candidates as the starting point of a longterm identificationcampaign. We propose a set of short XMMNewton observations to have a fullcoverage of these targets in order to investigate their spectra and morphologiesin details as well as to search for the associated compact stellar remnantsproduced in the supernova explosions. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
