    • GRB090426: the environment of a rest-frame 0.35-s gamma-ray burst at a redshift of 2.609 
      Levesque, Emily M.; Bloom, Joshua S.; Butler, Nathaniel R.; Perley, Daniel; Cenko, S. Bradley; Prochaska, Xavier; Kewley, Lisa; Bunker, Andrew; Chen, Hsiao-Wen; Chornock, Ryan; Filippenko, Alexei V.; Glazebrook, Karl; López Morales, Sebastián; Masiero, Joseph; Modjaz, Maryam; Morgan, Adam; Poznanski, Dovi (2010)
      We present the discovery of an absorption-line redshift of z = 2.609 for GRB 090426, establishing the first firm lower limit to a redshift for a gamma-ray burst (GRB) with an observed duration of <2 s.With a rest-frame ...
    • THE HIGH-METALLICITY EXPLOSION ENVIRONMENT OF THE RELATIVISTIC SUPERNOVA 2009BB1 
      Levesque, Emily M.; Soderberg, M.; Foley, Ryan J.; Berger, E.; Kewley, Lisa; Chakraborti, S.; Ray, Aurkie; Torres, M. A. P.; Challis, P.; Kirshner, Robert P.; Barthelmy, S. D.; Bietenholz, M. F.; Chandra, P.; Chaplin, V.; Chevalier, R. A.; Chugai, N.; Connaughton, V.; Copete, A.; Fox, O.; Fransson, C.; Grindlay, J. E.; Hamuy Wackenhut, Mario; Milne, P. A.; Pignata Libralato, Giuliano; Stritzinger, M. D.; Wieringa, M. H. (2009-12)
      We investigate the environment of the nearby (d 40 Mpc) broad-lined Type Ic supernova SN 2009bb. This event was observed to produce a relativistic outflow likely powered by a central ac- creting compact object. While ...
    • MULTI-WAVELENGTH OBSERVATIONS OF SUPERNOVA 2011ei: TIME-DEPENDENT CLASSIFICATION OF TYPE IIb AND Ib SUPERNOVAE ... 
      Vljevic, Dan Milisa; Margutti, Raffaella; Soderberg, Alicia; Pignata Libralato, Giuliano; Chomiuk, Laura; Fesen, Robert A.; Bufano, Filomena; Sanders, Nathan E.; Parrent, Jerod T.; Parker, Stuart; Mazzali, Paolo; Pian, Elena; Pickering, Timothy; Buckley, David A.; Crawford, Steven M.; Gulbis, Amanda A.; Hettlage, Christian; Hooper, Eric; Nordsieck, Kenneth H.; O’Donoghue, Darragh; Husser, Tim Oliver; Potter, Stephen; Kniazev, Alexei; Kotze, Paul; Romero Colmenero, Encarni; Vaisanen, Petri; Wolf, Marsha; Bietenholz, Michael F.; Bartel, Norbert; Fransson, Claes; Walker, Emma S.; Brunthaler, Andreas; Chakraborti, Sayan; Levesque, Emily M.; MacFadyen, Andrew; Drescher, Colin; Bock, Greg; Marples, Peter; Anderson, Joseph P.; Benetti, Stefano; Reichart, Daniel; Ivarsen, Kevin (The American Astronomical Society, 2013-04)
      We present X-ray, UV/optical, and radio observations of the stripped-envelope, core-collapse supernova (SN) 2011ei, one of the least luminous SNe IIb or Ib observed to date. Our observations begin with a discovery within ∼1 ...
    • SN 2009bb: A PECULIAR BROAD-LINED TYPE Ic SUPERNOVA 
      Pignata Libralato, Giuliano; Stritzinger, Maximilian; Soderberg, Alicia; Mazzali, Paolo; Phillips, M. M.; Morrell, Nidia; Anderson, Joseph P.; Boldt, Luis; Campillay, Abdo; Contreras, Carlos; Folatelli, Gastón; Förster, Francisco; González Tagle, Sergio; Hamuy Wackenhut, Mario; Krzeminski, Wojtek; Maza Sancho, José; Roth, Miguel; Salgado, Francisco; Levesque, Emily M.; Rest, Armin; Crain, J. Adam; Foster, Andrew C.; Haislip, Joshua B.; Ivarsen, Kevin M.; LaCluyze, Aaron P.; Nysewander, Melissa C.; Reichart, Daniel E. (2011-02-10)
      Ultraviolet, optical, and near-infrared photometry and optical spectroscopy of the broad-lined Type Ic supernova (SN) 2009bb are presented, following the flux evolution from -10 to +285 days past B-band maximum. Thanks to ...
    • SUPERNOVA 2008bk AND ITS RED SUPERGIANT PROGENITOR 
      Van Dyk, Schuyler D.; Davidge, Tim J.; Elias-Rosa, Nancy; Taubenberger, Stefan; Li, Weidong; Levesque, Emily M.; Howerton, Stanley; Pignata Libralato, Giuliano; Morrell, Nidia; Hamuy Wackenhut, Mario; Filippenko, Alexei V. (IOP PUBLISHING LTD, 2012-01)
      We have obtained limited photometric and spectroscopic data for supernova (SN) 2008bk in NGC 7793, primarily at greater than or similar to 150 days after explosion. We find that it is a Type II-Plateau (II-P) SN that most ...
