Supermagnified Stars in Lensing Clusters and Small-Scale Structure in the Dark Matter
Gabriel Torralba, Jordi Miralda-Escudé
Supermagnified stars, discovered by HST and JWST in lensing clusters of galaxies, are luminous stars in source galaxies lying near lensing caustics that are magnified by large fact…

First Statistical Study of Over 100 Magnified Stellar Events at Redshift with JWST
J. M. Palencia, Fengwu Sun, J. M. Diego +25
Highly magnified stars at cosmological distances () become detectable thanks to microlensing by intracluster stars near the critical curves of galaxy clusters. Multi…

Rethinking Resonance Detectability during Binary Neutron Star Inspiral: Accurate Mismatch Computations for Low-lying Dynamical Tides
Alberto Revilla-Peña, Ruxandra Bondarescu, Andrew P. Lundgren +1
We compute deviations from observed gravitational wave signals, where the amplitude of the signal is unchanged. As an example, we consider the detectability of low lying dynamical…
