      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 ...
    • High luminosity, slow ejecta and persistent carbon lines: SN 2009dc challenges thermonuclear explosion scenarios 

      Taubenberger, S.; Benetti, S.; Childress, M.; Pakmor, R.; Hachinger, S.; Mazzali, Paolo; Stanishev, V.; Elias-Rosa, Nancy; Agnoletto, I.; Bufano, Filomena; Ergon, M.; Harutyunyan, A.; Inserra, C.; Kankare, E.; Kromer, M.; Navasardyan, H.; Nicolas, J.; Pastorello, A.; Prosperi, E.; Salgado, F.; Sollerman, J.; Stritzinger, M.; Turatto, M.; Valenti, S.; Hillebrandt, W. (WILEY-BLACKWELL, 2011-04)
      Extended optical and near-IR observations reveal that SN 2009dc shares a number of similarities with normal Type Ia supernovae (SNe Ia), but is clearly overluminous, with a (pseudo-bolometric) peak luminosity of log (L) = ...

      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 ...

      Context. The Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) began as a public spectroscopic survey in April 2012. PESSTO classifies transients from publicly available sources and ...
    • The type Iax supernova, SN 2015H A white dwarf deflagration candidate 

      Magee, M. R.; Kotak, R.; Sim, S. A.; Kromer, M.; Rabinowitz, D.; Smartt, S. J.; Baltay, C.; Campbell, H. C.; Chen, T.

R.; Sullivan, M.; Valenti, S.; Young, D. R. (EDP Sciences, 2016)
      We present results based on observations of SN 2015H which belongs to the small group of objects similar to SN 2002cx, otherwise known as type Iax supernovae. The availability of deep pre-explosion imaging allowed us to ...
