The detection and characterization of highly magnified stars with JWST: Prospects of finding Population III
Erik Zackrisson, Adam Hultquist, Aron Kordt +10
Gravitational lensing may render individual high-mass stars detectable out to cosmological distances, and several extremely magnified stars have in recent years been detected out t…
Reaching for the stars -- JWST/NIRSpec spectroscopy of a lensed star candidate at
Lukas J. Furtak, Ashish K. Meena, Erik Zackrisson +31
We present JWST/NIRSpec observations of a highly magnified star candidate at a photometric redshift of , previously detected in JWST/NIRCam imaging of t…
The JWST Discovery of the Triply-imaged Type Ia "Supernova H0pe" and Observations of the Galaxy Cluster PLCK G165.7+67.0
Brenda L. Frye, Massimo Pascale, Justin Pierel +39
A Type Ia supernova (SN) at was discovered in James Webb Space Telescope Near Infrared Camera imaging of the galaxy cluster PLCK G165.7+67.0 (G165; ). The SN is…
JWST's PEARLS: Mothra, a new kaiju star at z=2.091 extremely magnified by MACS0416, and implications for dark matter models
J. M. Diego, Bangzheng Sun, Haojing Yan +28
We report the discovery of Mothra, an extremely magnified monster star, likely a binary system of two supergiant stars, in one of the strongly lensed galaxies behind the galaxy clu…
Hidden giants in JWST's PEARLS: An ultra-massive z=4.26 sub-millimeter galaxy that is invisible to HST
Ian Smail, Ugne Dudzeviciute, Mark Gurwell +32
We present a multi-wavelength analysis using SMA, JCMT, NOEMA, JWST, HST, and SST of two dusty strongly star-forming galaxies, 850.1 and 850.2, seen through the massive cluster len…
Gravitational lensing of gravitational waves: prospects for probing intermediate-mass black holes in galaxy lenses with global minima image
Ashish Kumar Meena
This work studies microlensing effects in strongly lensed gravitational wave (GW) signals corresponding to global minima images in galaxy-scale lenses. We find that stellar microle…
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…
Exotic Image Formation in Strong Gravitational Lensing by Clusters of Galaxies -- IV. Elliptical NFW Lenses and Hyperbolic Umbilics
Ashish Kumar Meena, Jasjeet Singh Bagla
A source lying near hyperbolic umbilic (HU) leads to a ring-like image formation, constituting four images with high magnification factors and lying in a small region of the lens p…
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…
Spatially Resolved Stellar Populations of Galaxies in WHL0137-08 and MACS0647+70 Clusters as Revealed by JWST: How do Galaxies Grow and Quench Over Cosmic Time?
Abdurro'uf, Dan Coe, Intae Jung +20
We study the spatially resolved stellar populations of 444 galaxies at in two clusters (WHL0137-08 and MACS0647+70) and a blank field, combining imaging data from HST a…
A search for transients in the Reionization Lensing Cluster Survey (RELICS): Three new supernovae
Miriam Golubchik, Adi Zitrin, Justin Pierel +16
The Reionization Cluster Survey (RELICS) imaged 41 galaxy clusters with the Hubble Space Telescope (HST), in order to detect lensed and high-redshift galaxies. Each cluster was ima…
