To investigate short GRB observations in the context of diverse kilonova behavior, we present a comprehensive optical and near-infrared (NIR) catalog of 85 bursts discovered over 2005-2020 on timescales of $\lesssim12$ days.

We present the detection of an unresolved radio source coincident with the position of the Type I superluminous supernova (SLSN) PTF10hgi ($z=0. 098$) about 7. 5 years post-explosion, with a flux density of $F_\nu(6\,\,{\rm GHz)}\approx 47. 3\ \mu Jy$ and a luminosity of $L_\nu(6\,\,{\rm GHz})\approx 1. 1\times 10^{28}$ erg s$^{-1}$ Hz$^{-1}$.

When the SN and CMB constraints are combined with constraints from BAO and local H0 measurements, the analysis yields the most precise measurement of dark energy to date: $w0 = -1. 007\pm 0. 089$ and $wa = -0. 222 \pm0. 407$ for the w0waCDM model.
