    • 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: ...
    • ESC supernova spectroscopy of non-ESC targets 
      Harutyunyan, A.; Pfahler, P.; Pastorello, A.; Taubenberger, S.; Turatto, M.; Cappellaro, E.; Benetti, Stefano; Elias-Rosa, Nancy; Navasardyan, H.; Valenti, S.; Stanishev, V.; Patat, F.; Riello, M.; Pignata Libralato, Giuliano; Hillebrandt, W. (EDP SCIENCES S A, 2008-09)
      Aims. We present the spectra of 36 supernovae (SNe) of various types, obtained by the European Supernova Collaboration. Because of the spectral classification and the phase determination at their discovery the SNe did not ...

      We present ultraviolet, optical and near-infrared observations of the interacting transient SN 2009ip, covering the period from the start of the outburst in 2012 October until the end of the 2012 observing season. The ...
    • 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 ...
    • Optical and infrared observations of SN 2002dj: some possible common properties of fast-expanding Type Ia ... 
      Pignata Libralato, Giuliano; Benetti, Stefano; Mazzali, Paolo; Kotak, Rubina; Patat, F.; Meikle, P.; Stehle, M.; Leibundgut, B.; Suntzeff, Nicholas B.; Buson, L. M.; Cappellaro, E.; Clocchiatti, A.; Hamuy Wackenhut, Mario; Maza Sancho, José; Mendez, J.; Ruiz Lapuente, P.; Salvo, M.; Schmidt, Brian P.; Turatto, M.; Hillebrandt, W. (BLACKWELL PUBLISHING, 2008-08-11)
      As part of the European Supernova Collaboration, we obtained extensive photometry and spectroscopy of the Type Ia supernova (SN Ia) SN 2002dj covering epochs from 11 d before to nearly two years after maximum. Detailed ...
    • The outermost ejecta of Type Ia supernovae 
      Tanaka, Masaomi; Mazzali, Paolo; Benetti, Stefano; Nomoto, Ken’ichi; Elias-Rosa, Nancy; Kotak, Rubina; Pignata Libralato, Giuliano; Stanishev, Vallery; Hachinger, Stephan (UNIV CHICAGO PRESS, 2008-04-10)
      The properties of the highest velocity ejecta of normal Type Ia supernovae (SNe Ia) are studied via models of very early optical spectra of six SNe. At epochs earlier than 1 week before maximum, SNe with a rapidly evolving ...

      Clocchiatti, Alejandro; Suntzeff, Nicholas B.; Phillips, Mark M.; Filippenko, Alexei V.; Turatto, Massimo; Benetti, Stefano; Cappellaro, Enrico; Avilés, Roberto; Covarrubias, Ricardo; DeGiogia Eastwood, K.; Dickinson, Mark.; Gouiffes, Christian; Guhathakurta, Puragra; Hamuy Wackenhut, Mario; Heathcote, Steve R.; Leibundgut, Bruno; Matheson, Thomas; Navarrete, Mauricio; Pérez, M.; Phillips, Andrew; Piemonte, Antonello; Ruiz González, María Teresa; Shields, Joseph C.; Smith, Chris; Spinrad, Hyron; Sturch, Conrad R.; Tyson, J. Anthony; Wells, Lisa (2001-06-01)
      We present a study of the Type Ic supernova (SN) 1990B that includes most of the observations obtained from around the world. The combined data set comprises 84 BV (RI)c photometric points spanning approximately 360 days ...
