4. Cluster-lensed supernovae with the Roman Space Telescope and Vera Rubin observatoryMateusz Bronikowski, Tanja Petrushevska, Justin Pierel, 2022, objavljeni povzetek znanstvenega prispevka na konferenci Opis: I will present our current efforts to enable the use of strongly lensed supernovae behind galaxy clusters as powerful tools to tackle several open questions in astrophysics and cosmology. As a preparatory task, we are collecting all available gravitational telescopes into a database, and estimating the properties of all reported multiply-imaged galaxies behind clusters. We are building a tool that will enable accurate estimates of cluster-lensed supernova yields for a given survey. In addition, we are developing the methods to extract the cosmological parameters from cluster-lensed supernovae in the Rubin and Roman data.
