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…

Signatures of Fuzzy Dark Matter Inside Radial Critical Curves
J. M. Palencia, Paloma Morilla, Sung Kei Li +5
We investigate the strong gravitational lensing properties of fuzzy dark matter (FDM) halos, focusing on the magnification properties near radial critical curves (CCs). Using simul…
