The swallowed spike: the formation of light primordial black hole structures around heavy seeds
Agnese Tolino, Francesca Scarcella, Bradley J. Kavanagh +2
Spikes are steep enhancements in the dark matter (DM) distribution around a heavy compact object. If the compact object is primordial, and the bulk of the DM is also composed of (l…
Caustic crossings in giant arcs with extended dark matter objects
Djuna Croon, Benedict Crossey, Jose Maria Diego +2
Caustic-crossing stars observed in giant arcs behind galaxy clusters provide a powerful probe of dark matter substructure. While previous work has focused on point-like lenses such…
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…
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…
