On the mass-metallicity relation, velocity dispersion and gravitational well depth of GRB host galaxies

Maryam Arabsalmani, Palle Møller, Johan P. U. Fynbo +4

We analyze a sample of 16 absorption systems intrinsic to long duration GRB host galaxies at $z\gtrsim 2$ for which the metallicities are known. We compare the relation between th…
