      Pian, E.; Mazzali, Paolo; Masetti, N.; Ferrero, P.; Klose, Sylvio; Palazzi, E.; Ramírez Ruiz, Enrico; Woosley, S. E.; Kouveliotou, C.; Deng, J.; Filippenko, Alexei V.; Foley, Ryan J.; Fynbo, Johan P. U.; Kann, D. A.; Li, Weidong; Hjorth, Jens; Nomoto, K.; Patat, F.; Sauer, D. N.; Sollerman, J.; Vreeswijk, Paul M.; Guenther, E. W.; Levan, A. J.; O'Brien, Peter; Tanvir, N. R.; Wijers, Ralph A. M.; Dumas, C.; Hainaut, O.; Wong, D. 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 ...
    • Rapid-response mode VLT/UVES spectroscopy of GRB060418 - Conclusive evidence for UV pumping from the time ... 
      Vreeswijk, Paul M.; Ledoux, C.; Smette, A.; Ellison, S.; Jaunsen, A. O.; Andersen, M. I.; Fruchter, Andrew S.; Fynbo, Johan P. U.; Hjorth, Jens; Kaufer, A.; Moller, P.; Petitjean, P.; Savaglio, S.; Wijers, Ralph A. M. (2007)
      We present high-resolution spectroscopic observations of GRB 060418, obtained with VLT/UVES. These observations were triggered using the VLT Rapid-Response Mode (RRM), which allows for automated observations of transient ...
    • The evolution of the Si IV content in the Universe from the epoch of reionization to cosmic noon 
      D'Odorico, V.; Finlator, K.; Cristiani, S.; Cupani, G.; Perrotta, S.; Calura, F.; Centurion, M.; Becker, G.; Berg, T. A. M.; López, S.; Ellison, S.; Pomante, E. (Oxford, 2022)
      We investigate the abundance and distribution of metals in the high-redshift intergalactic medium and circum-galactic medium through the analysis of a sample of almost 600 Si iv absorption lines detected in high and ...
