A Lens Finder Map to check claimed High-z Galaxies behind SMACS J0723.3-7327
Alex Chow, Sung Kei Li, Tom Broadhurst +5
The first science image released by the JWST reveals numerous galaxies in the distant background of the galaxy cluster SMACS J0723.3-7327. Some have claimed redshifts of up to $z \…
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…
