Dents in the Mirror: A Novel Probe of Dark Matter Substructure in Galaxy Clusters from the Astrometric Asymmetry of Lensed Arcs
Derek Perera, Daniel Gilman, Liliya L. R. Williams +5
Astrometric perturbations of lensed arcs behind galaxy clusters have been recently suggested as promising probes of small-scale () dark matter substructure.…
Testing Light Unaffiliated Mass Clumps in MACS 0416 on galaxy and galaxy cluster scales using JWST
Marceau Limousin, Derek Perera, Gregor Rihtarsic +2
Light unaffiliated mass clumps (LUMCs), i.e. dark matter (DM) components without any stellar counterparts, have been reported in strong lensing mass reconstructions of MACS 0416, b…
Microlensing at Cosmological Distances: Event Rate Predictions in the Warhol Arc of MACS 0416
J. M. Palencia, J. M. Diego, L. Dai +13
Highly magnified stars ( 100) are now outinely identified as transient events at cosmological distances thanks to microlensing by intra-cluster stars near the critical curve…
Constraining the z 1 Initial Mass Function with {\it HST} and {\it JWST} Lensed Stars in MACS J0416.1-2403
Sung Kei Li, Jose M. Diego, Ashish K. Meena +19
Our understanding of galaxy properties and evolution is contingent on knowing the initial mass function (IMF), and yet to date, the IMF is constrained only to local galaxies. Indiv…
