Ly-alpha and UV emission from high-redshift GRB hosts: To what extent do GRBs trace star formation?

P. Jakobsson, G. Bjornsson, J. P. U. Fynbo +9

We report the result of a search for Ly-alpha emission from the host galaxies of the gamma-ray bursts (GRBs) 030226 (z = 1.986), 021004 (z = 2.335) and 020124 (z = 3.198). We find…
