    • A blue point source at the location of supernova 2011DH 

      Folatelli, Gastón; Bersten, Melina C.; Benvenuto, Omar; Van Dyk, Schuyler D.; Kuncarayakti, Hanindyo; Maeda, Keiichi; Nozawa, Takaya; Nomoto, Ken’ichi; Hamuy Wackenhut, Mario; Quimby, Robert M. (The American Astronomical Society, 2014-10-01)
      We present Hubble Space Telescope (HST) observations of the field of the Type IIb supernova (SN) 2011dh in M51 performed at ≈1161 rest-frame days after explosion using the Wide Field Camera 3 and near-UV filters F225W ...
    • Bolometric light curves for 33 type II Plateau Supernovae 

      Bersten, Melina C.; Hamuy Wackenhut, Mario (2009-08-10)
      Using data of three well observed Type II plateau supernovae (SNe II-P), SNe 1987A, 1999em, and 2003hn, and two atmosphere models by Eastman et al. and Dessart & Hillier, we derive calibrations for bolometric corrections ...
    • Disappearance of the progenitor of supernova iptf13bvn 

      Folatelli, Gastón; Van Dyk, Schuyler D.; Kuncarayakti, Hanindyo; Maeda, Keiichi; Bersten, Melina C.; Nomoto, Ken'ichi; Pignata Libralato, Giuliano; Hamuy Wackenhut, Mario; Quimby, Robert M.; Zheng, WeiKang; Filippenko, Alexei V.; Clubb, Kelsey I.; Smith, Nathan; Elias Rosa, Nancy; Foley, Ryan J.; Miller, Adam A. (IOP Publishing, 2016)
      Supernova (SN) iPTF13bvn in NGC 5806 was the first Type Ib SN to have been tentatively associated with a progenitor in pre-explosion images. We performed deep ultraviolet (UV) and optical Hubble Space Telescope observations ...
    • The Progenitor of the Type IIb SN 2008ax Revisited 

      Folatelli, Gastón; Bersten, Melina C.; Kuncarayakti, Hanindyo; Benvenuto, Omar G.; Maeda, Keiichi; Nomoto, Ken’ichi (IOP Publishing, 2015)
      Hubble Space Telescope observations of the site of the supernova (SN) SN 2008ax obtained in 2011 and 2013 reveal that the possible progenitor object detected in pre-explosion images was in fact multiple. Four point sources ...
    • Supernova 2010as: the lowest-velocity member of a family of flat-velocity type IIb supernovae 

      Folatelli, Gastón; Bersten, Melina C.; Kuncarayakti, Hanindyo; Olivares Estay, Felipe; Anderson, Joseph P.; Holmbo, Simon; Maeda, Keiichi; Morrell, Nidia; Nomoto, Ken’ichi; Pignata Libralato, Giuliano; Stritzinger, Maximilian; Contreras, Carlos; Forster, Francisco; Hamuy Wackenhut, Mario; Phillips, Mark M.; Prieto, José Luis; Valenti, Stefano; Afonso, Paulo; Altenmuller, Konrad; Elliott, Jonny; Greiner, Jochen; Updike, Adria; Haislip, Joshua B.; LaCluyze, Aaron P.; Moore, Justin P.; Reichart, Daniel E. (The American Astronomical Society, 2014-09-01)
      We present extensive optical and near-infrared photometric and spectroscopic observations of the stripped-envelope supernova SN 2010as. Spectroscopic peculiarities such as initially weak helium features and low ...
