    • AFTERGLOW OBSERVATIONS OF FERMI LARGE AREA TELESCOPE GAMMA-RAY BURSTS AND THE EMERGING CLASS OF HYPER-ENERGETIC ... 
      Cenko, S. B.; Frail, D. A.; Harrison, F. A.; Haislip, Joshua B.; Reichart, Daniel E.; Butler, N. R.; Cobb, B. E.; Cucchiara, A.; Berger, E.; Bloom, J. S.; Chandra, P.; Fox, D. B.; Perley, Daniel; Prochaska, J. X.; Filippenko, A. V.; Glazebrook, K.; Ivarsen, K. M.; Kasliwal, M. M.; Kulkarni, S. R.; LaCluyze, Aaron P.; López, S.; Morgan, A. N.; Pettini, M.; Rana, V. R. (2011-05-01)
      We present broadband (radio, optical, and X-ray) light curves and spectra of the afterglows of four long-duration gamma-ray bursts (GRBs; GRBs 090323, 090328, 090902B, and 090926A) detected by the Gamma-Ray Burst Monitor ...
    • 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 ...
    • 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 ...
