    • Analysis of blueshifted emission peaks in Type II supernovae 
      Anderson, Joseph P.; Dessart, L.; Gutiérrez, Claudia P.; Hamuy Wackenhut, Mario; Morrell, N. I.; Phillips, M. M.; Folatelli, Gastón; Stritzinger, M. D.; Freedman, W. L.; González Gaitán, Santiago; McCarthy, P.; Suntzeff, Nicholas B.; Thomas-Osip, J. (Royal Astronomical Society, 2014-06-11)
      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, ...
