VizieR Online Data Catalog: Soft X-ray emission of Type Ia SN progenitors (Nielsen+, 2012)
Abstract
By searching the Chandra Data Archive, we found pre-explosion images taken with the Advanced CCD Imaging Spectrometer (ACIS-S) at the positions of 10 nearby (<25Mpc) SNe Ia. The SNe in question are SN2002cv, SN2003cg, SN2004W, SN2006X, SN2006dd, SN2006mr, SN2007gi, SN2007sr, SN2008fp and SN2011fe. No obvious sources were found on the pre-explosion images for any of these SNe.
For SN2002cv, SN2003cg, SN2004W, SN2006X, SN2006dd, SN2006mr, SN2007gi and SN2008fp, only a single pre-explosion Chandra image exists for each of the SNe, and SN2006dd and SN2006mr are on the same image. Several of these images have long (>30ks) exposure times. For SN2007sr and SN2011fe, multiple pre-explosion Chandra images exist, and these can be combined to give very long (several 100ks) exposure times. (3 data files).- Publication:
