Lensed stars in galaxy-galaxy strong lensing -- a JWST prediction for the Cosmic Horseshoe

Sung Kei Li, Luke Weisenbach, Thomas E. Collett +10

We explore for the first time the possibility of detecting lensed star transients in galaxy-galaxy strong lensing systems upon repeated, deep imaging using the {\it James-Webb Spac…

Magnification bias reveals severe contamination in Hubble Frontier Field photo-z catalogs

Jiashuo Zhang, Jeremy Lim, Tom Broadhurst +4

Gravitational lensing by massive galaxy clusters enables faint distant galaxies to be more abundantly detected than in blank fields, thereby allowing one to construct galaxy lumino…

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…

Multi-copy Axion Transfer Function and Observational Implications of Effective de Broglie Scales

Jiashuo Zhang, Tom Broadhurst, Jeremy Lim +2

Ultra-light axions are viable fuzzy/wave-like dark matter (DM) candidates generically predicted by the String Axiverse paradigm with multiple particle copies, whereas most of th…

Explaining JWST counts with galaxy formation models

Giorgio Manzoni, Tom Broadhurst, Jeremy Lim +18

A distinct power-law break is apparent m_AB approximately 21 in the deep Near-Infrared PEARLS-JWST galaxy counts. The break becomes more pronounced at longer wavelengths, with the…
