    • 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 ...
    • 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) = ...
    • INTERACTING SUPERNOVAE AND SUPERNOVA IMPOSTORS: SN 2009ip, IS THIS THE END?

E.; Tan, T. G.; Taubenberger, S.; Tomasella, L.; Turatto, M.; Wright, D. (The American Astronomical Society, 2013-04)
      We report the results of a three-year-long dedicated monitoring campaign of a restless luminous blue variable (LBV) in NGC 7259. The object, named SN 2009ip, was observed photometrically and spectroscopically in the optical ...

Sagues; Smith, K. W.; Sollerman, J.; Somero, A.; Wang, B.; Young, D. R. (EDP, 2021)
      We present the spectroscopic and photometric study of five intermediate-luminosity red transients (ILRTs), namely AT 2010dn, AT 2012jc, AT 2013la, AT 2013lb, and AT 2018aes. They share common observational properties and ...

P.; Sollerman, J.; Spyromilio, J.; Taubenberger, S.; Valentini, G.; Vennes, S.; Yoshii, Y. (Royal Astronomical Society, 2014-04-11)
      We present new data for five underluminous Type II-plateau supernovae (SNe IIP), namely SN 1999gn, SN 2002gd, SN 2003Z, SN 2004eg and SN 2006ov. This new sample of low-luminosity SNe IIP (LL SNe IIP) is analysed together ...
