VizieR Online Data Catalog: UVOT photometry of Super-Chandrasekhar mass SNe Ia (Brown+, 2014)

SC SNe are hot, high-energy explosions, so ultraviolet (UV) coverage is important to better measure the total luminosity and determine its origin, in particular whether it originates from shocks or simply a hot photosphere. The Ultraviolet/Optical Telescope (UVOT; Roming et al. 2005SSRv..120...95R) on the Swift satellite (Gehrels et al. 2004ApJ...611.1005G) presents an excellent opportunity to obtain unique, early-time UV data. This paper will focus on three objects: SN 2009dc - a well-studied member of the Super-Chandrasekhar mass SN class - and SNe 2011aa and 2012dn, which share some characteristics.
