  • Swift UVOT light curves of ASASSN-15lh

    We present the detection of persistent soft X-ray radiation with L_x_~10^41^-10^42^erg/s at the location of the extremely luminous, double-humped transient ASASSN-15lh as...
  • Swift-UVOT obs. analysis of 29 SNe Ia

    The intrinsic colors of Type Ia supernovae (SNe Ia) are important to understanding their use as cosmological standard candles. Understanding the effects of reddening and...
  • Absolute UV magnitudes of type Ia SNe

    We examine the absolute magnitudes and light-curve shapes of 14 nearby (redshift z=0.004-0.027) Type Ia supernovae (SNe Ia) observed in the ultraviolet (UV) with the Swift...
  • Photometry of SN 2008D

    On 2008 January 9.56 UT, SN 2008D was discovered while following up an unusually bright X-ray transient (XT) in the nearby spiral galaxy NGC 2770. We present early optical...
  • SNe Ia as NIR standard candles from PAIRITEL

    We have obtained 1087 NIR (JHK_s_) measurements of 21 SNe Ia using PAIRITEL, nearly doubling the number of well-sampled NIR SN Ia light curves. These data strengthen the...
  • ESSENCE supernova survey

    We describe the implementation and optimization of the ESSENCE supernova survey, which we have undertaken to measure the dark energy equation-of-state parameter,...
  • SDSS-II Supernova survey, 2005

    We present ugriz light curves for 146 spectroscopically-confirmed or spectroscopically-probable Type Ia supernovae (SNe) from the 2005 season of the Sloan Digital Sky Survey-II...
  • SN 2018ijp transient gri light curves

    In this paper, we discuss the outcomes of the follow-up campaign of SN 2018ijp, discovered as part of the Zwicky Transient Facility survey for optical transients. Its first...
  • SN Ia properties using bolometric light curves

    We present bolometric light curves constructed from multiwavelength photometry of Type Ia supernovae (SNe Ia) from the Carnegie Supernova Project and the CfA Supernova Group,...
  • Bgri light curves of PTF11kmb and PTF12bho

    We present the Palomar Transient Factory discoveries and the photometric and spectroscopic observations of PTF11kmb and PTF12bho. We show that both transients have properties...
  • SN and LGRB locations in their host galaxies

    When the afterglow fades at the site of a long-duration {gamma}-ray burst (LGRB), Type Ic supernovae (SNe Ic) are the only type of core-collapse supernova observed. Here we...
  • Radio emission from supernovae

    We report Very Large Array radio observations of 29 supernovae (SNe) with ages ranging from 10 days to about 90yr past explosion. These observations significantly contribute to...
