The characterization of galaxies at the highest redshifts remains one of the central goals in contemporary astrophysics. For the last two decades, GRBs have been heralded as effective diagnostic to probe the interstellar medium (ISM) of high-redshift faint star-forming galaxies and their metal content. An opportunity to fulfill this promise was provided by the bright GRB 210905A at redshift...

96. Host galaxies and local properties of a complete sample of short Gamma-Ray Bursts

Short gamma-ray bursts (SGRBs) represent a unique class of cosmic events offering valuable insights into the physics of compact object binary systems. From the combined detection of the gravitational wave (GW) event GW170817 with the corresponding electromagnetic counterparts - the kilonova AT2017gfo and the short GRB170817A - interest in compact object binary merger counterparts has...

100. Properties of the populations of Gamma Ray Bursts

The intrinsic properties of short and long Gamma-Ray Bursts (GRBs), including their cosmic rates, luminosity functions, and potential evolution with redshift, can be studied by integrating data from large GRB samples collected over the past 50 years. These datasets offer diverse observational constraints, with Swift providing the most extensive sample of GRBs with measured intrinsic...

170. Teaching an old BAT new tricks: New analysis methods and results with Swift/BAT-GUANO

In 2017 the detection of the faint GRB 170817A jointly with gravitational waves vaulted us into the era of multi-messenger astronomy, but it also showed us the need for an increased sensitivity to faint GRBs. This motivated efforts to develop sensitive, targeted searches for GRBs that run on the ground. The Gamma-ray Urgent Archiver for Novel Opportunities (GUANO) came online in 2019 to fill...
