Supermagnified Stars in Lensing Clusters and Small-Scale Structure in the Dark Matter
Gabriel Torralba, Jordi Miralda-Escudé
The paper describes how super‑magnified stars behind galaxy‑cluster lenses can be monitored for microlensing events, providing a sensitive probe of small‑scale dark‑matter structur…

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…

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…
