HOLISMOKES XX. Lens models of binary lens galaxies with five images of Supernova Winny
L. R. Ecker, A. G. Schweinfurth, R. Saglia +13
Strongly lensed supernovae (SNe) provide a powerful way to study cosmology, SNe and galaxies. Modelling the lens system is key to extracting astrophysical and cosmological informat…
