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…
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…
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…
BUFFALO/Flashlights: Constraints on the abundance of lensed supergiant stars in the Spock galaxy at redshift 1
Jose M. Diego, Sung Kei Li, Ashish K. Meena +27
We present a constraint on the abundance of supergiant (SG) stars at redshift z approx. 1, based on recent observations of a strongly lensed arc at this redshift. First we derive a…
Einstein rings modulated by wavelike dark matter from anomalies in gravitationally lensed images
Alfred Amruth, Tom Broadhurst, Jeremy Lim +10
Unveiling the true nature of Dark Matter (DM), which manifests itself only through gravity, is one of the principal quests in physics. Leading candidates for DM are weakly interact…
Flashlights: Properties of Highly Magnified Images Near Cluster Critical Curves in the Presence of Dark Matter Subhalos
Liliya L. R. Williams, Patrick L. Kelly, Tommaso Treu +7
Dark matter subhalos with extended profiles and density cores, and globular stars clusters of mass , that live near the critical curves in galaxy cluster lenses…
An analytic model for the sub-galactic matter power spectrum in fuzzy dark matter halos
Hiroki Kawai, Masamune Oguri, Alfred Amruth +2
Fuzzy dark matter (FDM), a scalar particle coupled to the gravitational field without self-interaction whose mass range is , is one of the prom…
