The Ero Host Galaxy of Grb 020127: Implications for the Metallicity of Grb Progenitors
We present optical and near-IR observations of the host galaxy of GRB 020127, for which we measure R Ks 1⁄4 6:2mag. This is only the second GRB host to date classified as an ERO. The spectral energy distribution (SED) is typical of a dusty starburst galaxy, with a redshift z 1:9, a luminosity L 5L , and an inferred stellar mass of M 10 10 M , two orders of magnitude moremassive than typical GRB...
متن کاملHost Galaxy of GRB 020127 : Implications for the Metallicity of GRB Progenitors
We present optical and near-IR observations of the host galaxy of GRB020127, for which we measure R−Ks = 6.2 mag. This is only the second GRB host to date, which is classified as an ERO. The spectral energy distribution is typical of a dusty starburst galaxy, with a redshift, z ≈ 1.9, a luminosity, L ≈ 5 L, and an inferred stellar mass of M∗ ∼ 10 11 − 10 M⊙, two orders of magnitude more massive...

متن کاملOn the Origin of the Mass-metallicity Relation for Grb Host Galaxies
We investigate the nature of the mass-metallicity (M -Z) relation for long gamma-ray burst (LGRB) host galaxies. Recent studies suggest that the M -Z relation for local LGRB host galaxies may be systematically offset towards lower metallicities relative to theM -Z relation defined by the general star forming galaxy (SDSS) population. The nature of this offset is consistent with suggestions that...
متن کاملThe metallicity dependence of the long-duration GRB rate from host galaxy luminosities
We investigate the difference between the host galaxy properties of core-collapse supernovae and long-duration gamma-ray bursts (LGRBs), and quantify a possible metallicity dependence of the efficiency of producing LGRBs. We use a sample of 16 CC SNe and 16 LGRBs from Fruchter et al. (2006) which have similar redshift distributions to eliminate galaxy evolution biases. We make a forward predict...
