Early Results from GLASS-JWST. XIX: A High Density of Bright Galaxies at in the Abell 2744 Region
Marco Castellano, Adriano Fontana, Tommaso Treu +38
We report the detection of a high density of redshift galaxies behind the foreground cluster Abell 2744, selected from imaging data obtained recently with NIRCam onbo…
Evolution of the Mass-Metallicity Relation from Redshift to the Local Universe
Danial Langeroodi, Jens Hjorth, Wenlei Chen +17
A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of this correlation can s…
Flashlights: More than A Dozen High-Significance Microlensing Events of Extremely Magnified Stars in Galaxies at Redshifts z=0.7-1.5
Patrick L. Kelly, Wenlei Chen, Amruth Alfred +23
Once only accessible in nearby galaxies, we can now study individual stars across much of the observable universe aided by galaxy-cluster gravitational lenses. When a star, compact…
Two lensed star candidates at behind the galaxy cluster MACS J0647.7+7015
Ashish Kumar Meena, Adi Zitrin, Yolanda Jiménez-Teja +24
We report the discovery of two extremely magnified lensed star candidates behind the galaxy cluster MACS J0647.7+7015, in recent multi-band James Webb Space Telescope (JWST) NIRCam…
Flashlights: An Off-Caustic Lensed Star at Redshift = 1.26 in Abell 370
Ashish Kumar Meena, Wenlei Chen, Adi Zitrin +10
We report the discovery of a transient seen in a strongly lensed arc at redshift in \emph{Hubble Space Telescope} imaging of the Abell 370 galaxy cluster. The tr…
JWST's PEARLS: a new lens model for ACT-CL J01024915, "EL Gordo'', and the first red supergiant star at cosmological distances discovered by JWST
Jose M. Diego, Ashish K. Meena, Nathan J. Adams +27
The first JWST data on the massive colliding cluster El Gordo confirm 23 known families of multiply lensed images and identify 8 new members of these families. Based on these famil…
