      In classical P-Cygni profiles, theory predicts emission to peak at zero rest velocity. However, supernova spectra exhibit emission that is generally blueshifted. While this characteristic has been reported in many SNe, ...

      Supernova (SN) 2017cbv in NGC 5643 is one of a handful of Type Ia supernovae (SNe Ia) reported to have excess blue emission at early times. This paper presents extensive BVRIYJHK(s)-band light curves of SN 2017cbv, covering ...
    • Martínez, L.; Bersten, M. C.; Anderson, J. P.; González Gaitán, S.; Forster Burón, Francisco; Folatelli, Gastón (EDP Science, 2020)
      Context. The progenitor and explosion properties of type II supernovae (SNe II) are fundamental to understanding the evolution of massive stars. Particular attention has been paid to the initial masses of their progenitors, ...

Chris; Turatto, Massimo (IOP Publishing Ltd., 2017)
      We present 888 visual-wavelength spectra of 122 nearby type II supernovae (SNe II) obtained between 1986 and 2009, and ranging between 3 and 363 days post-explosion. In this first paper, we outline our observations and ...
    • Gutiérrez, Claudia P.; Anderson, Joseph P.; Hamuy Wackenhut, Mario; González Gaitán, Santiago; Galbany, Lluis; Dessart, Luc; Stritzinger, Maximilian D.; Phillips, Mark M.; Morrell, Nidia; Folatelli, Gastón (IOP Publishing Ltd., 2017)
      We present an analysis of observed trends and correlations between a large range of spectral and photometric parameters of more than 100 type II supernovae (SNe II), during the photospheric phase. We define a common epoch ...
