VENUS: A Strongly Lensed Clumpy Galaxy at behind the Galaxy Cluster MACS J0257.1-2325
Minami Nakane, Vasily Kokorev, Seiji Fujimoto +75
We present the discovery of a strongly lensed galaxy at , dubbed the ``Misty Moons'', identified in the JWST Treasury Survey, Vast Exploration for Nascent, Unexplored S…
Gravitational lensing of 21 cm HI signal: detection prospects at z ~ 1 with uGMRT in galaxy cluster lenses
Sauraj Bharti, Ashish Kumar Meena, J. S. Bagla
The atomic hydrogen HI content of galaxies is intimately related to star formation and galaxy evolution through the baryon cycle, which involves processes such as accretion, feedba…
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…
JWST's PEARLS: A Candidate Massive Binary Star System in a Lensed Galaxy at Redshift 0.94
Hayley Williams, Patrick L. Kelly, Emmanouil Zapartas +18
Massive stars at cosmological distances can be individually detected during transient microlensing events, when gravitational lensing magnifications may exceed ~1000. Nine such sou…
JWST's PEARLS: Temperatures of Nine Highly Magnified Stars in a Galaxy at Redshift 0.94 and Simulated Stellar Population Dependence on Stellar Metallicity and the Initial Mass Function
Hayley Williams, Patrick L. Kelly, Rogier A. Windhorst +17
We present stellar atmosphere modeling of JWST NIRCam photometry of nine highly magnified individual stars in a single galaxy at redshift z=0.94 known as the Warhol arc, which is s…
Transient star B/R ratio and star formation in lensed galaxies
Sung Kei Li, Jose M. Palencia, Jose M. Diego +8
The extreme magnification from galaxy clusters and microlenses therein allows the detection of individual, luminous stars in lensed galaxies as transient events, and hence provides…
Microlensing at Cosmological Distances: Event Rate Predictions in the Warhol Arc of MACS 0416
J. M. Palencia, J. M. Diego, L. Dai +13
Highly magnified stars ( 100) are now outinely identified as transient events at cosmological distances thanks to microlensing by intra-cluster stars near the critical curve…
Constraining the z 1 Initial Mass Function with {\it HST} and {\it JWST} Lensed Stars in MACS J0416.1-2403
Sung Kei Li, Jose M. Diego, Ashish K. Meena +19
Our understanding of galaxy properties and evolution is contingent on knowing the initial mass function (IMF), and yet to date, the IMF is constrained only to local galaxies. Indiv…
Flashlights: Prospects for constraining the Initial Mass Function around cosmic noon with caustic-crossing events
Ashish Kumar Meena, Sung Kei Li, Adi Zitrin +7
The Flashlights program with the Hubble Space Telescope imaged the six Hubble Frontier Fields galaxy clusters in two epochs and detected twenty transients. These are primarily expe…
Cosmology with supernova Encore in the strong lensing cluster MACS J01382155: photometry, cluster members, and lens mass model
S. Ertl, S. H. Suyu, S. Schuldt +23
The strongly lensed Supernova (SN) Encore at a redshift of , discovered behind the galaxy cluster MACS J01382155 at , provides a rare opportunity for time-de…
