Fine-Tuned Search for Kilonova Emission in a Short Gamma-Ray Burst: Implications for the Progenitors, GW Sources, and r-Process Nucleosynthesis

Project: Research project

Project Details

Description

Short gamma-ray bursts originate from neutron star mergers, and the aim of this HST proposal is to pinpoint their “kilonova” optical and near-infrared emission. The origin of the kilonova emission is from the radioactive decay of heavy elements produced in the merger and thus lends crucial insight into the contribution of neutron star mergers to the Universe’s heavy element budget. Because short gamma-ray bursts are detected at cosmological distances, and kilonovae are rapidly fading sources, this requires HST to uncover them.

Co-I Fong and a post-doctoral associate in her group (PD) who will primarily be responsible for the rapid analysis of the HST data and light curve extraction to incorporate those data into a publication along with other complementary multi-wavelength data.
