VizieR Online Data Catalog: 19yrs of radio and X-ray obs. of SN 2001em (Chandra+, 2020)

Abstract

We observed SN 2001em with the Giant Metrewave Radio Telescope (GMRT) on 2004 February 13 at 1.3GHz. We also observed SN 2001em with the upgraded GMRT in frequency band 3 (250-500MHz), band 4 (550-900MHz), and band 5 (1000-1450MHz) in 2019 December. The VLA observations started in 2003 October and continued until July 2020. The data from the years 2003-2008 were obtained with the old VLA covering the frequency range 1.4-22.5GHz. We obtained Chandra archival data on SN 2001em at five epochs between 2004 April and 2016 August. XMM-Newton observed SN 2001em on 2006 June for an exposure of around 25ks. The XRT on board Swift observed SN2001em at various epochs during 2008-2016 January.
