GRB091127/SN2009nz and the VLT/X-shooter spectroscopy of its host galaxy: probing the faint end of the mass-metallicity relation
Gamma-rays bursts: individual: GRB091127 – supernovae: individual: SN2009nz – Galaxies: ISM– Galaxies: evolution

We perform a detailed study of the gamma-ray burst GRB091127/SN2009nz host galaxy at z=0.490 using the VLT/X-shooter spectrograph in slit and integral-field unit (IFU). From the analysis of the optica...
