JWST observations of gravitational lensing by galaxy clusters

Our team is leading two JWST Cycle 1 programs GO 1433 and 2282. Other JWST programs observing lensing clusters include the ERO, GLASS, TEMPLATES, UNCOVER, CANUCS, and PEARLS.


A galaxy cluster magnifying distant galaxies and the individual star system Earendel, observed by JWST in 2022 July and December.

Sunrise Arc + Earendel

The most highly magnified galaxy observed in the first billion years, revealing parsec-scale star clusters and the individual star system Earendel.


One of the most distant galaxies ever seen by Hubble (z ~ 11, observed 400 Myr after the Big Bang) revealed to have two components by JWST and still one of the brightest (AB mag 25) known at this distance.
