    • Adaptive optics discovery of supernova 2004ip in the nuclear regions of the luminous infrared galaxy IRAS 18293-3413 

      Mattila, Seppo; Väisänen, Petri H.; Farrah, Duncan G.; Efstathiou, Andreas; Meikle, W. P.S.; Dahlén, Tomas; Fransson, Claes; Lira, Paulina; Lundqvist, Peter; Östlin, Göran; Ryder, Stuart D.; Sollerman, Jesper (2007-04-10)
      We report a supernova discovery in Ks-band images from the NAOS CONICA adaptive optics (AO) system on the ESO Very Large Telescope. The images were obtained as part of a near-infrared search for highly obscured supernovae ...
    • Core-collapse supernovae missed by optical surveys 

      Mattila, Seppo S.; Dahlén, Tomas; Efstathiou, Andreas; Kankare, Erkki; Melinder, Jens; Alonso-Herrero, Almudena; Pérez-Torres, M. A.; Ryder, Stuart D.; Väisänen, Petri H.; Östlin, Göran (2012-09-10)
      We estimate the fraction of core-collapse supernovae (CCSNe) that remain undetected by optical SN searches due to obscuration by large amounts of dust in their host galaxies. This effect is especially important in luminous ...
