    • Effects of the explosion asymmetry and viewing angle on the Type Ia supernova colour and luminosity calibration 

      Maeda, Keiichi; Leloudas, Giorgos; Taubenberger, Stefan; Stritzinger, Maximilian; Sollerman, Jesper; Elias Rosa, Nancy; Benetti, Stefano; Hamuy Wackenhut, Mario; Folatelli, Gastón; Mazzali, Paolo (2011)
      Phenomenological relations exist between the peak luminosity and other observables of type Ia supernovae (SNe Ia) that allow one to standardize their peak luminosities. However, several issues are yet to be clarified: ...
    • 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 ...
    • Supernova 2010ev: A reddened high velocity gradient type Ia supernova 

      Gutiérrez Aveldaño, Claudia; González Gaitán, Santiago; Folatelli, Gastón; Pignata Libralato, Giuliano; Anderson, Joseph; Hamuy Wackenhut, Mario; Stritzinger, Maximilian; Taubenberger, Stefan; Bufano, Filomena; Olivares, Felipe; Haislip, Joshua B.; Reichart, Daniel (EDP Sciences, 2016)
      Aims. We present and study the spectroscopic and photometric evolution of the type Ia supernova (SN Ia) 2010ev. Methods. We obtain and analyze multiband optical light curves and optical/near-infrared spectroscopy at low ...
