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…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63
MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
JWST's PEARLS: Prime Extragalactic Areas for Reionization and Lensing Science: Project Overview and First Results
Rogier A. Windhorst, Seth H. Cohen, Rolf A. Jansen +82
We give an overview and describe the rationale, methods, and first results from NIRCam images of the JWST "Prime Extragalactic Areas for Reionization and Lensing Science" ("PEARLS"…
HST strong-lensing model for the first JWST galaxy cluster SMACS J0723.3-7327
Miriam Golubchik, Lukas J. Furtak, Ashish K. Meena +1
On 2022 July 8, NASA shared the list of five public showcase targets which have been observed with the new \textit{James Webb Space Telescope} (JWST), and whose data are expe…
Early results from GLASS-JWST VIII: An Extremely Magnified Blue Supergiant Star at Redshift 2.65 in the Abell 2744 Cluster Field
Wenlei Chen, Patrick L. Kelly, Tommaso Treu +18
We report the discovery of an extremely magnified star at redshift in James Webb Space Telescope (JWST) NIRISS pre-imaging of the Abell 2744 galaxy-cluster field. The star…
Unscrambling the lensed galaxies in JWST images behind SMACS0723
Massimo Pascale, Brenda L. Frye, Jose Diego +16
The first deep field images from the James Webb Space Telescope (JWST) of the galaxy cluster SMACS~J0723.3-7327 reveal a wealth of new lensed images at uncharted infrared wavelengt…
Gravitational Lensing of Gravitational Waves: Probability of Microlensing in Galaxy-Scale Lens Population
Ashish Kumar Meena, Anuj Mishra, Anupreeta More +2
With the increase in the number of observed gravitational wave (GW) signals, detecting strongly lensed GWs by galaxies has become a real possibility. Lens galaxies also contain mic…
An Efficient Method for Simulating Light Curves of Cosmological Microlensing and Caustic Crossing Events
Ashish Kumar Meena, Ofir Arad, Adi Zitrin
A new window to observing individual stars and other small sources at cosmological distances was opened recently, with the detection of several caustic-crossing events in galaxy cl…
