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…

RXJ0437+00: Constraining Dark Matter with Exotic Gravitational Lenses

David J. Lagattuta, Johan Richard, Harald Ebeling +6

We present the first strong-gravitational-lensing analysis of the galaxy cluster RXJ0437.1+0043 (RXJ0437; z = 0.285). Newly obtained, deep MUSE observations, Keck/MOSFIRE near-infr…

Multiply lensed star forming clumps in the A521-sys1 galaxy at redshift 1

Matteo Messa, Miroslava Dessauges-Zavadsky, Johan Richard +6

We study the population of star-forming clumps in A521-sys1, a system gravitationally lensed by the foreground () cluster Abell 0521. The galaxy presents o…

Precision modeling of JWST's first cluster lens SMACSJ0723.3-7327

Guillaume Mahler, Mathilde Jauzac, Johan Richard +12

Exploiting the fundamentally achromatic nature of gravitational lensing, we present a lens model for the massive galaxy cluster SMACSJ0723.3-7323 (SMACSJ0723, z=0.388) that signifi…

Ram pressure stripping in the z~0.5 galaxy cluster MS 0451.6-0305

Florence Durret, Lucie Degott, Catarina. Lobo +3

The pressure exerted by the ambient hot X-ray gas on cluster galaxies can lead to the presence of ram pressure stripped (RPS) galaxies, characterized by asymmetric shapes, and, in…

REQUIEM-2D: A diversity of formation pathways in a sample of spatially-resolved massive quiescent galaxies at z~2

Mohammad Akhshik, Katherine E. Whitaker, Joel Leja +16

REQUIEM-2D (REsolving QUIEscent Magnified galaxies with 2D grism spectroscopy) is comprised of a sample of 8 massive () strongly lensed quiescent galaxies…
