| Description: |
JWST data from PEARLS programme ID 2738 is publicly available on the MAST portal and accessible at this link. Accompanying HST data from TREASUREHUNT is available from https://doi.org/10.17909/wv13-qc14. JWST data from CEERS is publicly available at https://ceers.github.io/dr07.html. The FITS cutouts for all wavebands, including RMS noise maps and PSFs for all 16 candidates are made available at https://zenodo.org/records/15846915. ; We present four galaxy scale lenses discovered in two James Webb Space Telescope ( JWST ) blank-fields: the ∼54 arcmin2 of the PEARLS North-Ecliptic-Pole Time-Domain Field (NEP TDF) and in the ∼90 arcmin2 of CEERS. We perform the search by visual inspection of NIRCam photometric data, obtaining an initial list of 16 lens candidates. We down-select this list to five high-confidence lens candidates, based on lens modelling of the image configuration and photometric redshift measurements for both the source and the deflector. We compare our results to samples of lenses obtained in ground-based and space-based lens searches and theoretical expectations. We expect that JWST observations of field galaxies will yield approximately one galaxy scale lens every three to four NIRCam pointings of comparable depth to these observations ( ∼9 arcmin2 each). This shows that JWST , compared to other lens searches, can yield an extremely high number of secure lenses per unit area, with redshift and size distributions complementary to lens samples obtained from ground-based and wide-area surveys. We estimate that a single JWST pure-parallel survey of comparable depth could yield ∼80 galaxy scale lenses, with a third of them having zlens > 1 and zsource > 3. ; GF and JSBW acknowledge the support of the Australian Research Council Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D), through project number CE170100013, and the we acknowledge support from the ERC Advanced Investigator grant EPOCHS (788113), as well as two studentships from STFC.
