Spatially Resolved Physical Properties of Young Star Clusters and Star-forming Clumps in the Brightest z>6 Galaxy, the Strongly Lensed Cosmic Spear at z=6.2

Abdurro'uf, Dan Coe, Tom Resseguier +49

We present spatially resolved analysis of stellar populations in the brightest galaxy known to date (AB mag 23), the strongly lensed MACS0308zD1 (dubbed the ``Cosmic Spear…

Little red dot variability over a century reveals black hole envelope via a giant Einstein cross

Zijian Zhang, Mingyu Li, Masamune Oguri +79

"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…

VENUS: When Red meets Blue -- A multiply imaged Little Red Dot with an apparent blue companion behind the galaxy cluster Abell 383

Miriam Golubchik, Lukas J. Furtak, Joseph F. V. Allingham +50

We report the discovery of a doubly-imaged Little Red Dot (LRD) candidate behind the galaxy cluster Abell 383, which we dub A383-LRD1. Initially classified as a dropout galaxy in H…

SLICE: SPT-CL J0546-5345 -- A prominent strong-lensing cluster at

Joseph F. V. Allingham, Adi Zitrin, Miriam Golubchik +15

Massive galaxy clusters act as prominent strong-lenses. Due to a combination of observational biases, cluster evolution and lensing efficiency, most of the known cluster lenses lie…

The Kaleidoscope Survey: Strong Gravitational Lensing in Galaxy Clusters with Radial Arcs

Catherine Cerny, Mathilde Jauzac, David Lagattuta +5

We measure the dark matter density profiles of six galaxy clusters: A383, MS 2137-23, MACS J0326.8-0043, MACS J1427.6-2521, MACS J0417.5-1154, and MACS J0949.8+1708. Each cluster c…
