Optical Photometry of GRB 021004: The First Month
Stephen T. Holland, Michael Weidinger, Johan P. U. Fynbo +17
We present U,B,V,R_C,and I_C photometry of the optical afterglow of the gamma-ray burst GRB 021004 taken at the Nordic Optical Telescope between approximately eight hours and 30 da…
Absorption Systems in the Spectrum of GRB 021004
P. Møller, J. P. U. Fynbo, J. Hjorth +10
We report on a 3600 s spectrum of GRB 021004 obtained with the Nordic Optical Telecope on La Palma 10.71 hours after the burst. We identify absorption lines from five systems at re…
The low mas end of the young cluster IC2391
David Barrado y Navascues, John R. Stauffer
By collecting optical and infrared photometry, as well as medium resolution spectroscopy, we have discovered a sample of low mass stars and brwon dwarfs in the young cluster IC2391…
Coherent systems and Brill-Noether theory
Steven Bradlow, Oscar Garcia-Prada, Vicente Muñoz +1
Let be a curve of genus . A coherent system on consists of a pair where is an algebraic vector bundle of rank and degree and is a subspace…
The afterglow and complex environment of the optically dim burst GRB 980613
Jens Hjorth, Bjarne Thomsen, Svend R. Nielsen +15
We report the identification of the optical afterglow of GRB 980613 in R- and I-band images obtained between 16 and 48 hours after the gamma-ray burst. Early near-infrared (NIR) H…
