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 (DM) fluctuations near the critical curves of cluster gravitational lenses. We describe t…
Dark Matter distinguished by skewed microlensing in the "Dragon Arc"
Tom Broadhurst, Sung Kei Li, Amruth Alfred +18
Microlensed stars recently discovered by JWST & HST follow closely the winding critical curve of A370 along all sections of the ``Dragon Arc" traversed by the critical curve. These…
Imaging dark matter at the smallest scales with lensed stars
J. M. Diego, Sung Kei Li, Alfred Amruth +19
Observations of caustic-crossing galaxies at redshift show a wealth of transient events. Most of them are believed to be microlensing events of highly magnified stars. Ea…
Flashlights: Transients among Gravitationally-Lensed Star Clusters in the Dragon Arc. I. Stellar Microlensing vs Stellar Outbursts
Sung Kei Li, Jose M. Diego, Patrick L. Kelly +8
We report the discovery of transients among star clusters in a distant galaxy that is gravitationally lensed by a foreground galaxy cluster, and explore whether these transients co…
On the Evidence for Molecular Outflows in High-redshift Dusty Star-forming Galaxies
James Nianias, Jeremy Lim, Michael Yeung
Galactic-scale outflows of molecular gas from star-forming galaxies constitute the most direct evidence for regulation of star formation. In the early universe (), such ou…
