title = "Swift UVOT observations of type Ia Supernovae",
abstract = "We review recent UV observations of thermonuclear supernovae (SNe Ia) performed with the Swift Ultraviolet/Optical Telescope (UVOT) during its first two years. The UV light curves are found to have highly homogeneous light curve shapes, with peak dates that are similar to the peak dates in the U band (which is ∼2days earlier than in the B band). Optically-bright SNe Ia are found to be UV bright, as optically-faint SNe Ia are found to be UV faint. These findings are of interest for the cosmological utilization of SNe Ia as standard candles, and they afford insight into the thermonuclear explosion. The SN 2005ke was observed to feature a UV excess at late times presumably due to the SN shock encountering the circumstellar emission from a red giant donor star in the progenitor system. Collectively, Swift UV/X-ray observations of SNe Ia bear the promise of dramatically improving the understanding of type Ia SNe over the course of the upcoming years.",
