The galaxy density environment of gamma-ray burst host galaxies

We analyze cross-correlation functions between gamma-ray burst (GRB) hosts and surrounding galaxies. We have used data obtained with the Very Large Telescope at Cerro Paranal (Chile), as well as public Hubble Space Telescope data. Our results indicate that GRB host galaxies do not reside in high gal...
