Preliminary Evidence for Lensing-induced Alignments of High-redshift Galaxies in JWST-CEERS

Preliminary Evidence for Lensing-induced Alignments of High-redshift Galaxies in JWST-CEERS

The majority of low-mass ( ${\mathrm{log}}_{10}{M}_{* }/{M}_{\odot }=9\mbox{--}10$ ) galaxies at high redshift ( z  > 1) appear elongated in projection. We use JWST-CEERS observations to explore the role of gravitational lensing in this puzzle. The typical galaxy–galaxy lensing shear γ  ∼ 1% is t...
