A tale of two mergers: constraints on kilonova detection in two short GRBs at z ∼ 0.5

We present a detailed multiwavelength analysis of two short gamma-ray bursts (sGRBs)
detected by the Neil Gehrels Swift Observatory: GRB 160624A at= 0.483 and GRB 200522A
at= 0.554. These sGRBs demonstrate very different properties in their observed emission
and environment. GRB 160624A is associated with a late-type galaxy with an old stellar
population (≈ 3 Gyr) and moderate ongoing star formation (≈ 1 M⊙ yr− 1). Hubble and
Gemini limits on optical/near-infrared emission from GRB 160624A are among the most …
