    • Adaptive optics discovery of supernova 2004ip in the nuclear regions of the luminous infrared galaxy IRAS ... 
      Mattila, S.; Väisänen, P.; Farrah, D.; Efstathiou, A.; Meikle, W. P. S.; Dahlen, T.; Fransson, C.; Lira Teillery, Paulina; Lundqvist, P.; Östlin, G.; Ryder, S.; Sollerman, J. (2007)
      We report a supernova discovery in K-s-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 ...
    • THE HIGH-METALLICITY EXPLOSION ENVIRONMENT OF THE RELATIVISTIC SUPERNOVA 2009BB1 
      Levesque, Emily M.; Soderberg, M.; Foley, Ryan J.; Berger, E.; Kewley, Lisa; Chakraborti, S.; Ray, Aurkie; Torres, M. A. P.; Challis, P.; Kirshner, Robert P.; Barthelmy, S. D.; Bietenholz, M. F.; Chandra, P.; Chaplin, V.; Chevalier, R. A.; Chugai, N.; Connaughton, V.; Copete, A.; Fox, O.; Fransson, C.; Grindlay, J. E.; Hamuy Wackenhut, Mario; Milne, P. A.; Pignata Libralato, Giuliano; Stritzinger, M. D.; Wieringa, M. H. (2009-12)
      We investigate the environment of the nearby (d 40 Mpc) broad-lined Type Ic supernova SN 2009bb. This event was observed to produce a relativistic outflow likely powered by a central ac- creting compact object. While ...
    • The normal Type Ia SN 2003hv out to very late phases 
      Leloudas, G.; Stritzinger, M. D.; Sollerman, J.; Burns, C. R.; Kozma, C.; Krisciunas, K.; Maund, J. R.; Milne, P.; Filippenko, A. V.; Fransson, C.; Ganeshalingam, M.; Hamuy Wackenhut, Mario; Li, W.; Phillips, M. M.; Schmidt, B. P.; Skottfelt, J.; Taubenberger, S.; Boldt, L.; Fynbo, J. P. U.; Gonzalez, L.; Salvo, M.; Thomas-Osip, J. (EDP Sciences, 2009-10)
      Aims. We study a thermonuclear supernova (SN), emphasizing very late phases. Methods. An extensive dataset for SN 2003hv that covers the flux evolution from maximum light to day + 786 is presented. This includes 82 ...
    • A relativistic type Ibc supernova without a detected gamma-ray burst 
      Soderberg, A. M.; Chakraborti, S.; Pignata Libralato, Giuliano; Chevalier, R. A.; Chandra, P.; Ray, A.; Wieringa, M. H.; Capote, A.; Chaplin, V.; Connaughton, V.; Barthelmy, S. D.; Bietenholz, M. F.; Chugai, N.; Stritzinger, M. D.; Hamuy Wackenhut, Mario; Fransson, C.; Fox, O.; Levesque, E. M.; Grindlay, J. E.; Challis, P.; Foley, R. J.; Kirshner, R. P.; Milne, P. A.; Torres, M. A. P. (2010)
      Long duration c-ray bursts (GRBs) mark1 the explosive death of some massive stars and are a rare sub-class of type Ibc supernovae. They are distinguished by the production of an energetic and collimated relativistic outflow ...
    • The Type II supernovae 2006V and 2006au: two SN 1987A-like events 
      Taddia, F.; Stritzinger, M. D.; Sollerman, J.; Phillips, M. M.; Anderson, Joseph P.; Ergon, M.; Folatelli, Gastón; Fransson, C.; Freedman, W.; Hamuy Wackenhut, Mario; Morrell, N.; Pastorello, A.; Persson, S. E.; González, S. (EDP SCIENCES S A, 2012-01)
      Context. Supernova 1987A revealed that a blue supergiant (BSG) star can end its life as a core-collapse supernova (SN). SN 1987A and other similar objects exhibit properties that distinguish them from ordinary Type II ...
