    • GRB090426: the environment of a rest-frame 0.35-s gamma-ray burst at a redshift of 2.609 
      Levesque, Emily M.; Bloom, Joshua S.; Butler, Nathaniel R.; Perley, Daniel; Cenko, S. Bradley; Prochaska, Xavier; Kewley, Lisa; Bunker, Andrew; Chen, Hsiao-Wen; Chornock, Ryan; Filippenko, Alexei V.; Glazebrook, Karl; López Morales, Sebastián; Masiero, Joseph; Modjaz, Maryam; Morgan, Adam; Poznanski, Dovi (2010)
