Abstract (from CDS):

We present data and initial results from VLT/X-Shooter emission-line spectroscopy of 96 galaxies selected by long γ-ray bursts (GRBs) at 0.1<z<3.6, the largest sample of GRB host spectra available to date. Most of our GRBs were detected by Swift and 76% are at 0.5<z<2.5 with a median zmed∼1.6. Based on Balmer and/or forbidden lines of oxygen, nitrogen, and neon, we measure systemic redshifts, star formation rates (SFR), visual attenuations (AV), oxygen abundances (12+log(O/H)), and emission-line widths (σ). We study GRB hosts up to z∼3.5 and find a strong change in their typical physical properties with redshift. The median SFR of our GRB hosts increases from SFRmed∼0.6M/yrat z∼0.6 up to SFRmed∼15M/yr at z∼2. A higher ratio of [OIII]/[OII] at higher redshifts leads to an increasing distance of GRB-selected galaxies to the locus of local galaxies in the Baldwin-Phillips-Terlevich diagram. There is weak evidence for a redshift evolution in AV and σ, with the highest values seen at z∼1.5 (AV) or z∼2 (σ). Oxygen abundances of the galaxies are distributed between 12+log(O/H)=7.9 and 12+log(O/H)=9.0 with a median 12+log(O/H)med∼8.5. The fraction of GRB-selected galaxies with super-solar metallicities is ∼20% at z<1 in the adopted metallicity scale. This is significantly less than the fraction of total star formation in similar galaxies, illustrating that GRBs are scarce in high metallicity environments. At z∼3, sensitivity limits us to probing only the most luminous GRB hosts for which we derive metallicities of Z≲0.5Z. Together with a high incidence of Z∼0.5Z galaxies at z∼1.5, this indicates that a metallicity dependence at low redshift will not be dominant at z∼3. Significant correlations exist between the hosts' physical properties. Oxygen abundance, for example, relates to AV (12+log(O/H)∝0.17.AV), line width (12+log(O/H)∝σ0.6), and SFR (12+log(O/H)∝SFR0.2). In the last two cases, the normalization of the relations shift to lower metallicities at z>2 by ∼0.4dex. These properties of GRB hosts and their evolution with redshift can be understood in a cosmological context of star-forming galaxies and a picture in which the hosts' properties at low redshift are influenced by the tendency of GRBs to avoid the most metal-rich environments.
