Evidence for diffuse molecular gas and dust in the hearts of gamma-ray burst host galaxies
J. Bolmer, C. Ledoux, P. Wiseman +17
Here we built up a sample of 22 GRBs at redshifts observed with X-shooter to determine the abundances of hydrogen, metals, dust, and molecular species. This allows us to st…

The 2175 Å extinction feature in the optical afterglow spectrum of GRB 180325A at z=2.25
T. Zafar, K. E. Heintz, J. P. U. Fynbo +26
The UV extinction feature at 2175 Å is ubiquitously observed in the Galaxy but is rarely detected at high redshifts. Here we report the spectroscopic detection of the 2175 Å bump o…

Spotting high-z molecular absorbers using neutral carbon: Results from a complete spectroscopic survey with the VLT
P. Noterdaeme, C. Ledoux, S. Zou +4
While molecular quasar absorption systems provide unique probes of the physical and chemical properties of the gas as well as original constraints on fundamental physics and cosmol…
