Abstract:
We present the updated census and statistics of Lyman-alpha emitting
long gamma-ray bursts host galaxies (LAE-LGRBs). We investigate the
properties of a sub-sample of four LAE-LGRBs (GRBs: 011211, 021004,
060926, 070110). The combined observations of their afterglow and host
galaxy allow us to test the shell model commonly used to fit
Lyman-alpha emission line spectra.
Description:
Flux-calibrated VLT/X-shooter medium resolution spectra of GRB host
galaxies, selected to show Lyman-alpha emission lines toghether with
Balmer and Oxygen emission lines. Wavelengths are in the observed
frame, in vacuum, and in a heliocentric reference frame. Fluxes are in
units of erg/s/cm2/Å and are all corrected for Galactic
foreground reddening according to Schlafly & Finkbeiner
(2011ApJ...737..103S 2011ApJ...737..103S). Fluxes are not corrected for host extinction or
slit losses.
