    • Are the hosts of gamma-ray bursts sub-luminous and blue galaxies? 
      Le Floc’h, E.; Duc, P.-A; Mirabel, I. F.; Sanders, D. B.; Bosch, G.; Diaz, R. J.; Donzelli, C. J.; Rodrigues, I.; Courvoisier, T. J. L.; Greiner, J.; Mereghetti, S.; Melnick, J.; Maza Sancho, José; Minniti, D. (EDP Sciences, 2003-03)
      We present K-band imaging observations of ten gamma-ray burst (GRB) host galaxies for which an optical and/or radio afterglow associated with the GRB event was clearly identified. Data were obtained with the Very Large ...
    • THE EVOLUTION OF SWIFT/BAT BLAZARS AND THE ORIGIN OF THE MeV BACKGROUND 
      Ajello, M.; Costamante, L.; Sambruna, R. M.; Gehrels, N.; Chiang, J.; Rau, A.; Escala, A.; Greiner, J.; Tueller, J.; Wall, J. V.; Mushotzky, R. F (IOP PUBLISHING LTD, 2009-07-01)
      We use three years of data from the Swift/Burst Alert Telescope ( BAT) survey to select a complete sample of X-ray blazars above 15 keV. This sample comprises 26 flat-spectrum radio quasars (FSRQs) and 12 BL Lacertae (BL ...
    • An optical supernova associated with the X-ray flash XRF 060218 
      Pian, E.; Mazzali, Paolo; Masetti, N.; Ferrero, P.; Klose, Sylvio; Palazzi, E.; Ramírez Ruiz, Enrico; Woosley, S.

S.; Baade, D.; Wang, L.; Amati, L.; Cappellaro, E.; Castro Tirado, A. J.; Ellison, S.; Frontera, F.; Fruchter, Andrew S.; Greiner, J.; Kawabata, K.; Ledoux, C.; Maeda, K.; Møller, P.; Nicastro, L.; Rol, E.; Starling, R. (NATURE PUBLISHING GROUP, 2006-08-31)
      Long-duration gamma-ray bursts (GRBs) are associated with type Ic supernovae(1) that are more luminous than average(2-5) and that eject material at very high velocities. Less-luminous supernovae were not hitherto known to ...
