The metallicity and star formation activity of long gamma-ray burst hosts for z\(<\)3: insights from the Illustris simulation
We study the properties of long gamma-ray bursts (LGRBs) using a large scale hydrodynamical cosmological simulation, the Illustris simulation. We determine the LGRB host populations under different thresholds for the LGRB progenitor metallicities, according to the collapsar model. We compare the sim...
