TL;DR: In this article, the authors present polarimetric observations of the afterglow of gamma-ray burst (GRB) 021004, obtained with the Nordic Optical Telescope (NOT) and the Very Large Telescope (VLT) between 8 and 17 hours after the burst.
Journal ArticleDOI
Constraints on (Omega_m,Omega_Lambda) using distributions of inclination angles for high redshift filaments
TL;DR: In this paper, a scale free method to determine the cosmological parameters (Omega_m, Omega_Lambda) is presented, based on the requirement of isotropy of the distribution of orientations of cosmologically filaments.
