Photometric redshift of the GRB 981226 host galaxy
L. Christensen, J. Hjorth, J. Gorosabel
No optical afterglow was found for the dark burst GRB 981226 and hence no absorption redshift has been obtained. We here use ground-based and space imaging observations to analyse…
Gamma-Ray Burst Selected High Redshift Galaxies: Comparison to Field Galaxy Populations to z~3
C. J. Conselice, P. M. Vreeswijk, A. S. Fruchter +6
We study the internal structural properties of 37 long duration gamma-ray burst (GRB) host galaxies imaged with the Hubble Space Telescope. Fitting exponential disk and r^1/4 model…
The GRB 030329 host: a blue low metallicity subluminous galaxy with intense star formation
J. Gorosabel, D. Pérez-Ramírez, J. Sollerman +13
We present broad band photometry and spectroscopic observations of the host galaxy of GRB 030329. Analysis of the spectral emission lines shows that the host is likely a low metall…
Determination of stellar shape in microlensing event MOA 2002-BLG-33
N. J. Rattenbury, F. Abe, D. P. Bennett +30
We report a measurement of the shape of the source star in microlensing event MOA 2002-BLG-33. The lens for this event was a close binary whose centre-of-mass passed almost directl…
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…
The red optical afterglow of GRB 030725
G. Pugliese, P. Møller, J. Gorosabel +6
We present a photometric study of the optical counterpart of the long-duration Gamma Ray Burst (GRB) 030725, which triggered the HETE FREGATE and WXM instruments on July 25th, 2003…
