Query: Probing Kilonova Ejecta Properties Using a Catalog of Short Gamma-Ray
  Burst Observations   The discovery of GW170817 and GRB 170817A in tandem with AT 2017gfo cemented
the connection between neutron star mergers, short gamma-ray bursts (GRBs), and
kilonovae. 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. The sample includes previously unpublished observations of 23 bursts, and
encompasses both detections and deep upper limits. We identify 11.8% and 15.3%
of short GRBs in our catalog with upper limits that probe luminosities lower
than those of AT 2017gfo and a fiducial NSBH kilonovae model (for pole-on
orientations), respectively. We quantify the ejecta masses allowed by the
deepest limits in our catalog, constraining blue and `extremely blue' kilonova
components of 14.1% of bursts to $M_{\rm ej}\lesssim0.01-0.1 M_{\odot}$. The
sample of short GRBs is not particularly constraining for red kilonova
components. Motivated by the large catalog as well as model predictions of
diverse kilonova behavior, we investigate modified search strategies for future
follow-up to short GRBs. We find that ground-based optical and NIR observations
on timescales of $\gtrsim 2$ days can play a significant role in constraining
more diverse outcomes. We expect future short GRB follow up efforts, such as
from the {\it James Webb Space Telescope}, to expand the reach of kilonova
detectability to redshifts of $z\approx 1$.
