1. A possible relativistic jetted outburst from a massive black hole fed by a tidally disrupted star.

    Science 333(6039):203 (2011) PMID 21680812

    Gas accretion onto some massive black holes (MBHs) at the centers of galaxies actively powers luminous emission, but most MBHs are considered dormant. Occasionally, a star passing too near an MBH is torn apart by gravitational forces, leading to a bright tidal disruption flare (TDF). Although th...
  2. No supernovae associated with two long-duration gamma-ray bursts.

    Nature 444(7122):1047 (2006) PMID 17183316

    It is now accepted that long-duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star. The standard 'collapsar' model predicts that a broad-lined and luminous type Ic core-collapse supernova accompanies every long-duration GRB. This association has been confirmed in ob...
  3. An introduction to a conference and a field

    New Astronomy Reviews 49(7):335 (2005)

    An introduction to the conference is presented. Some of the opportunities and difficulties for the future of wide-field imaging from space are discussed.
  4. A very energetic supernova associated with the gamma-ray burst of 29 March 2003.

    Nature 423(6942):847 (2003) PMID 12815425

    Over the past five years evidence has mounted that long-duration (>2 s) gamma-ray bursts (GRBs)-the most luminous of all astronomical explosions-signal the collapse of massive stars in our Universe. This evidence was originally based on the probable association of one unusual GRB with a supernov...
