Finding Core Collapse Supernova from the Epoch of Reionization Behind Cluster Lenses
Tony Pan, Abraham Loeb
TL;DR
This paper predicts that JWST can detect high-redshift core-collapse supernovae magnified by galaxy cluster lenses, aiding studies of the early universe during reionization.
Contribution
It introduces a method to identify distant supernovae using gravitational lensing effects from galaxy clusters with JWST.
Findings
JWST can detect supernovae at z > 7-8
Gravitational lensing extends supernova visibility
Potential to study reionization epoch supernovae
Abstract
Current surveys are underway to utilize gravitational lensing by galaxy clusters with Einstein radii >35" in the search for the highest redshift galaxies. Associated supernova from the epoch of reionization would have their fluxes boosted above the detection threshold, extending their duration of visibility. We predict that the James Webb Space Telescope (JWST) will be able to discover lensed core-collapse supernovae at redshifts exceeding z=7-8.
