Detailed photometric, spectroscopic, and modeling study of a low-redshift GRB-SN yielding nickel mass 0.4-0.5 solar masses, ejected mass 4-6 solar masses, and evidence for large-offset explosion in sub-solar metallicity gas.
No coincident GW signals found with long GRBs in O3 run; luminosity distance limits set assuming binary merger powering.
