Absorption spectroscopy of GRB160410A: The first complete study of the ISM of a short GRB

Short gamma-ray bursts (sGRBs) are produced on the coalescence of two compact objects such as two neutron stars. These cataclismic events release a large amount of energy in gravitational waves during the coalescence event to a single compact object. In this poster, we present the results of the study of GRB 160410A and GRB 201221D, two short GRBs that present very different environments.
