Receipt: # 17232-2 ----- Attempting Submission 3 (Thu Nov 16 19:49:02 GMT 2023) ----- Identifying the fingerprints of r-process heavy metals in a short GRB The afterglow of some short GRBs displays a late-time rebrightening, visible in the near-infrared a few days after the burst. This late-time bump could be explained as kilonova emission, providing a direct link to neutron star mergers, and a compelling proof for the synthesis of heavy nuclei through the rapid neutron capture process (r-process). We propose a multi-wavelength follow-up campaign of a nearby (z<0.4) short GRB in order to detect the expected kilonova bump and constrain its properties. Multi-band observations, and in particular X-rays, are critical to pin down the nature of the observed rebrightening, and to distinguish it from the standard afterglow emission. We will trigger on a GRB at z<0.4 and observable by Chandra. For most cases, observations will start within a week from the GRB and will involved deep imaging of the field. However, nearby events differ from the general population and a later start of the observations could be possible. In these cases, imaging might be replaced with grism spectroscopy if the source is sufficiently bright. Based on past experience, filters F606W (UVIS) and F110W/F160W (IR) are the most likely to be used. However, given the unknown distance of the source, some flexibility in the filter choice should be warranted. For example, F814W/F850LP in the optical, and F105W/F125W/F140W in the IR are also plausible choices that could optimize the science for a given redshift and source brightness. n/a Stellar Physics and Stellar Types 6 false false false false false false false false SUPPORTED STAR GAMMA RAY BURSTER X-RAY TRANSIENT J2000 STAR GAMMA RAY BURSTER X-RAY TRANSIENT J2000 STAR GAMMA RAY BURSTER X-RAY TRANSIENT J2000 GRB at z<0.4 WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F160W WFC3/UVIS Imaging No No F606W WFC3/IR Spectroscopic No No G102 WFC3/IR Spectroscopic No No G141 WFC3/UVIS Imaging No No F606W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F160W WFC3/IR Imaging No No F110W WFC3/IR Imaging No No F160W WFC3/UVIS Imaging No No F606W WFC3/IR Spectroscopic No No G102 WFC3/IR Spectroscopic No No G141 POS-TARG DITHER 0.173 LINE 0.112 false false 81.785 4 23.884 WFC3-UVIS-DITHER-BOX 1 false POS-TARG DITHER 0.572 LINE 0.365 false false 74.653 4 18.528 WFC3-IR-DITHER-BOX-MIN 2 false POS-TARG DITHER DITHER 4 0.65 WFC3-IR-DITHER-BOX-MIN false 74.653 false 0.365 0.572 2 0 POS-TARG LINE 18.528 3 true POS-TARG DITHER 0.605 LINE false false 3 41.788 WFC3-IR-DITHER-LINE-3PT 4 false POS-TARG DITHER 0.135 LINE false false 3 46.84 WFC3-UVIS-DITHER-LINE-3PT 5 false Timing link suitability includes constraints ([21 After 18 by 4.0 to 6.0 days]) The scheduling data was generated by CASM 31.1.
