Abstract:
The recent UNCOVER survey with the James Webb Space Telescope (JWST)
exploits the nearby cluster A2744 to create the deepest view of our
Universe to date by leveraging strong gravitational lensing. In this
work, we perform photometric fitting of more than 50000 robustly
detected sources out to z∼15. We show the redshift evolution of
stellar ages, star formation rates, and rest- frame colors across the
full range of 0.2≲z≲15. The galaxy properties are inferred using the
Prospector Bayesian inference framework using informative
Prospector-β priors on the masses and star formation histories to
produce joint redshift and stellar populations posteriors.
Additionally, lensing magnification is performed on the fly to ensure
consistency with the scale-dependent priors. We show that this
approach produces excellent photometric redshifts with
σNMAD∼0.03, of a similar quality to the established
photometric redshift code EAzY. In line with the open-source
scientific objective of this Treasury survey, we publicly release the
stellar population catalog with this paper, derived from our
photometric catalog adapting aperture sizes based on source profiles.
Description:
As part of UNCOVER DR2, we have released F277W+F356W+F444W-selected
photometric catalogs containing total fluxes for 61648 sources
(Weaver+ 2024, J/ApJS/270/7). In this work we fit galaxy SEDs to the
"supercatalog," which uses adaptive aperture selection based on their
isophotal areas following Labbe+ (2003AJ....125.1107L 2003AJ....125.1107L). See Section 2.
