Spectra from the XSHOOTER GRB afterglow legacy sample (XS-GRB) released

Published: 10 Oct 2018

This data release provides 1D spectra of 103 individual afterglows that were observed with the XSHOOTER spectrograph within 48 hours of the GRB trigger. The data release includes a few late-time host observations also for completeness. The total collection of spectra represents all GRB afterglows that have been followed up with XSHOOTER before March 31st, 2017. This date marks the end of the XS-GRB legacy follow-up program. Redshifts have been measured for 97% of these sources, covering a redshift range from 0.059 to 7.84, hence this dataset provides a unique resource to study the ISM across cosmic time.

The provided reduced spectra, available via the Science Portal and the spectroscopic query form, include estimates of the continuum and telluric absorption corrections. Please find more information in the release description.
