    • The Intermediate Luminosity Optical Transient Sn 2010da: The Progenitor, Eruption, and Aftermath of a Peculiar Supergiant High-Mass X-Ray Binary 

      Villar, Victoria Ashley; Berger, Edo; Chornock, R.; Margutti, R.; Laskar, T.; Brown, P. J.; Blanchard, Peter Kelly; Czekala, Ian Philip; Lunnan, R.; Reynolds, M. T. (American Astronomical Society, 2016)
      We present optical spectroscopy, ultraviolet-to-infrared imaging, and X-ray observations of the intermediate luminosity optical transient (ILOT) SN 2010da in NGC 300 (d = 1.86 Mpc) spanning from −6 to +6 years relative to ...

    • The Offset and Host Light Distributions of Long Gamma-Ray Bursts: A New View From Hst Observations of Swift Bursts 

      Blanchard, Peter Kelly; Berger, Edo; Fong, Wen-fai (American Astronomical Society, 2016)
      We present the results of an extensive Hubble Space Telescope (HST) imaging study of ∼100 Swift longduration gamma-ray bursts (LGRBs) spanning 0.03 . z . 9.4 using relative astrometry from ground- and space-based afterglow ...

    • PS1-14bj: A Hydrogen-poor Superluminous Supernova with a Long Rise and Slow Decay. 

      Lunnan, R.; Chornock, R.; Berger, Edo; Milisavljevic, Danny; Jones, D. O.; Rest, A.; Fong, W.; Fransson, C.; Margutti, R.; Drout, M. R.; Blanchard, Peter Kelly; Challis, P.; Cowperthwaite, Philip Steven; Foley, R. J.; Kirshner, Robert P.; Morrell, N.; Riess, A. G.; Roth, K. C.; Scolnic, D.; Smartt, S. J.; Smith, K. W.; Villar, Victoria Ashley; Chambers, K. C.; Draper, P. W.; Huber, M. E.; Kaiser, N.; Kudritzki, R.-P.; Magnier, E. A.; Metcalfe, N.; Waters, C. (American Astronomical Society, 2016)
      We present photometry and spectroscopy of PS1-14bj, a hydrogen-poor superluminous supernova (SLSN) at redshift z = 0.5215 discovered in the last months of the Pan-STARRS1 Medium Deep Survey. PS1-14bj stands out by its ...

      We present observations of SN 2015bn (=PS15ae = CSS141223-113342+004332 = MLS150211-113342+004333), a Type I superluminous supernova (SLSN) at redshift z = 0.1136. As well as being one of the closest SLSNe I yet discovered, ...

    • An Ultraviolet Excess in the Superluminous Supernova Gaia16apd Reveals a Powerful Central Engine 

      Nicholl, Matthew R.; Berger, Edo; Margutti, R; Blanchard, Peter Kelly; Milisavljevic, Danny; Challis, Peter M.; Metzger, B.D.; Chornock, R. (American Astronomical Society, 2017)
      Since the discovery of superluminous supernovae (SLSNe) in the last decade, it has been known that these events exhibit bluer spectral energy distributions than other supernova subtypes, with significant output in the ...

    • X-Rays from the Location of the Double-humped Transient ASASSN-15lh 

      Margutti, R; Metzger, B. D.; Chornock, R; Milisavljevic, Danny; Berger, Edo; Blanchard, Peter Kelly; Guidorzi, C.; Migliori, G.; Kamble, Atish; Lunnan, R; Nicholl, Matthew R.; Coppejans, D. L.; Dall’Osso, S.; Drout, M. R.; Perna, R.; Sbarufatti, B. (American Astronomical Society, 2017)
      We present the detection of persistent soft X-ray radiation with ${L}_{x}\sim {10}^{41}$–1042 erg s–1 at the location of the extremely luminous, double-humped transient ASASSN-15lh as revealed by Chandra and Swift. We ...
