      Two known and five novel 9,10-dihydrophenanthrene derivatives, two orsellinic acid derivatives and a lunularic acid derivative have been isolated from the liverwort Plagiochila spinulosa and identified following NMR studies. ...

    • The Early-Time Optical Properties of Gamma-Ray Burst Afterglows 

      Melandri, A.; Mundell, C.G.; Kobayashi, S.; Guidorzi, C.; Gomboc, A.; Steele, I.A.; Smith, R.J.; Bersier, D.; Mottram, C.J.; Carter, D.; Bode, M.F.; O'Brien, P.T.; Tanvir, N.; Rol, E.; Chapman, R. (2008)
      We present a multiwavelength analysis of 63 gamma-ray bursts observed with the world's three largest robotic optical telescopes, the Liverpool and Faulkes Telescopes (North and South). Optical emission was detected for 24 ...

      Pandey, S.B.; Swenson, C.A.; Perley, D.A.; Guidorzi, C.; Wiersema, K.; Malesani, D.; Akerlof, C.; Ashley, M.C.B.; Bersier, D.; Cano, Z.; Gomboc, A.; Ilyin, I.; Jakobsson, P.; Kleiser, I.K.W.; Kobayashi, S.; Kouveliotou, C.; Levan, A.; McKay, T.A.; Melandri, A.; Mottram, C.J.; Mundell, C.G.; O'Brien, P.T.; Phillips, A.; Rex, J.M.; Siegel, M.H.; Smith, R.J.; Steele, I.A.; Stratta, G.; Tanvir, N.; Weights, D.; Yost, S.A.; Yuan, F.; Zheng, W. (2010)
      The optical-infrared afterglow of the Large Area Telescope (LAT)-detected long-duration burst, GRB 090902B, has been observed by several instruments. The earliest detection by ROTSE-IIIa occurred 80 minutes after detection ...

(2009)
      Context. X-ray flashes (XRFs) are a class of gamma-ray bursts (GRBs) with a peak energy of the time-integrated spectrum, , typically below 30 keV, whereas classical GRBs have of a few hundreds of keV. Apart from and the ...
