  2. Astrophysics: a story of singular degeneracy.

    Nature 451(7180):775 (2008) PMID 18273005

  3. A runaway collision in a young star cluster as the origin of the brightest supernova.

    Nature 450(7168):388 (2007) PMID 18004377

    Supernova SN 2006gy in the galaxy NGC 1260 is the most luminous recorded. Its progenitor might have been a very massive (>100 Mo, where is the mass of the Sun) star, but that interpretation is incompatible with hydrogen in the spectrum of the supernova; stars >40 Moare believed to have shed thei...
  4. Astronomy. Double pulsar jackpot.

    Science 303(5661):1143 (2004) PMID 14976299

  5. 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...
