Abstract:
We propose a new strategy of finding strongly lensed supernovae (SNe)
by monitoring known galaxy-scale strong-lens systems. Strongly lensed
SNe are potentially powerful tools for the study of cosmology, galaxy
evolution, and stellar populations, but they are extremely rare. By
targeting known strongly lensed star-forming galaxies, our strategy
significantly boosts the detection efficiency for lensed SNe compared
to a blind search. As a reference sample, we compile the 128
galaxy-galaxy strong-lens systems from the Sloan Lens ACS Survey
(SLACS), the SLACS for the Masses Survey, and the Baryon Oscillation
Spectroscopic Survey Emission-Line Lens Survey. Within this sample, we
estimate the rates of strongly lensed Type Ia SN (SNIa) and
core-collapse SN (CCSN) to be 1.23±0.12 and 10.4±1.1 events per
year, respectively. The lensed SN images are expected to be widely
separated with a median separation of 2". Assuming a conservative
fiducial lensing magnification factor of 5 for the most highly
magnified SN image, we forecast that a monitoring program with a
single-visit depth of 24.7mag (5σ point source, r band) and a
cadence of 5days can detect 0.49 strongly lensed SNIa event and 2.1
strongly lensed CCSN events per year within this sample. Our proposed
targeted-search strategy is particularly useful for prompt and
efficient identifications and follow-up observations of strongly
lensed SN candidates. It also allows telescopes with small fields of
view and limited time to efficiently discover strongly lensed SNe with
a pencil-beam scanning strategy.
