A high-resolution view of the source-plane magnification near cluster caustics in wave dark matter models

Jose M. Diego, Alfred Amruth, Jose M. Palencia +10

We present the highest resolution images to date of caustics formed by wave dark matter ( $ψ$ DM) fluctuations near the critical curves of cluster gravitational lenses. We describe t…

Imaging dark matter at the smallest scales with $z \approx 1$ lensed stars

J. M. Diego, Sung Kei Li, Alfred Amruth +19

Observations of caustic-crossing galaxies at redshift $0.7 < z < 1$ show a wealth of transient events. Most of them are believed to be microlensing events of highly magnified stars. Ea…
