NIRCam primary / NIRISS parallel mosaic release
July 13, 2023
Updated mosaics for the Abell 2744 NIRCam and UNCOVER NIRISS parallel imaging (Nov 2,4,7, & 15, 2022) are now available!
As with the previous mosaics, the short- (F090W, F115W, F150W, F200W) and long-wavelength bands (F277W, F356W, F410M, F444W) use pixel scales of 0.02" and 0.04", respectively. All filters have the same WCS, which is defined so that the short-wavelength pixels can be binned 2x2 to directly match the long-wavelength images. Note that the footprint has been expanded from the DR1 mosaics to fully include the DDT-2767 area — the full NIRCam footprint now covers 49 square arcmin.
Additionally, mosaics of all existing HST data are provided, produced with the same WCS and footprint and a 0.04" pixel scale.
These mosaics include data from the following programs:- JWST/NIRCAM: GO-2561 (UNCOVER), ERS-1324 (GLASS), DD-2767
- JWST/NIRISS: GO-2561 (UNCOVER), ERS-1324 (GLASS)
- HST/ACS: #11689 (PI: Dupke), #13386 (PI: Rodney), #13495 (PI: Lotz / HFF), #13389 (PI: Siana), #15117 (PI: Steinhardt / BUFFALO), #17231 (PI: Treu)
- HST/WFC3: #13495 (PI: Lotz / HFF), #15117 (PI: Steinhardt / BUFFALO)

Lens model updated release: v1.1
July 25, 2023
Authors: Lukas J. Furtak and Adi Zitrin
The UNCOVER strong lensing (SL) model is a parametric SL model constructed with the UNCOVER JWST data using a new (grid-free) analytic method by A. Zitrin.
In this model release (v1.1), we supply WCS-registered FITS maps of the deflection field (in pixels), convergence, shear, and the lensing potential normalized to Dds/Ds=1. We also supply magnification maps for various source redshifts: 1, 2, 4, 6, 8, 10, 15 and 20. The lensing maps have a FoV of 7.6' x 7.6', which covers the entire central UNCOVER field. We provide maps for the best-fit model in two resolutions, a high-resolution version in 0.04"/pix (JWST NIRCam resolution) and a low-resolution version with 0.1"/pix. Compared to the v1.0 models, we added an additional spectroscopic redshift in the north-western sub-structure as well as six new multiple images. The additional constraints improve the model RMS down to 0.5.
Please cite Furtak et al. 2023 when using any of the lensing maps provided here.

Updated photometric catalog release
September 29, 2023
The DR2 Photometric Catalog contains significant improvements over DR1 including a "SUPER" catalog with photometry determined from optimally-selected color apertures, improved identification of stars and artifacts, and the complete 49 sq arcmin coverage of all available JWST imaging over Abell 2744.
All catalogs are based on F444W PSF-matched imaging, where the bright cluster galaxies and ICL have been modeled and subtracted. Detection was performed on a noise-equalized long-wavelength image (F277W+F356W+F444W). In addition to photometry, the catalogs contain basic photometric redshifts and rest-frame fluxes derived using EAZY, ALMA fluxes from DUALZ (Fujimoto et al. 2023) where available, and lensing magnifications for each object based on the updated v1.1 lensing maps of Furtak et al. 2022.
For full details, please see the README and the catalog paper.

Stellar population catalogs release
December 8, 2023
UPDATE: The catalogs released on October 2, 2023 have SFR/sSFR incorrectly labeled as averaged over 100 Myr, but those are in fact averaged over ~10 Myr. This problem has been corrected in this version (DR2.1; v3 on zenodo). Please refer to the README for further details. All links now point to the updated DR2.1 files.
October 2, 2023
The UNCOVER DR2 stellar population sythesis (SPS) catalog is based on the "SUPER" DR2 photometric catalog, with optimally determined aperture sizes per object. The SPS modeling is performed with the Prospector inference framework (Johnson et al. 2021). The modeling assumes a non-parametric, logarithmically-spaced SFH, as well as a mass function prior, a Gaussian mass-metallicity prior, and a dynamic SFH(M, z) prior from Prospector-β to optimize the photometric inference over the wide parameter space covered by deep JWST surveys (Wang et al. 2023). A second catalog with fixed redshifts to literature spec-zs (not including any UNCOVER MSA spec-zs) is also available.
For full details, please see the README and the catalog paper.

DUALZ: ALMA x JWST Public Legacy Field Abell 2744
September 14, 2023
Author: Seiji Fujimoto
The ALMA maps, cubes, and source catalog (v1.0) from the Deep UNCOVER-ALMA Legacy High-Z (DUALZ) Survey are now available!
DUALZ features a contiguous ~4'x6' ALMA 30-GHz-wide mosaic in Band 6, covering all high magnification areas (μ>2) down to a sensitivity of sigma = 32.7 μJy/beam, referred to as the "Wide" map. To leverage the ancillary data sets from the previous ALMA programs in A2744, we also created deep ALMA maps & cubes around the primary cluster (~2'x2') by combining our data with that of ALMA-HFF (Muñoz Arancibia et al. 2023) and ALCS (Fujimoto et al. 2023b), referred to as "Deep" map. The sensitivity decreases down to sigma = 27.7 μJy/beam in the Deep map. The default products are produced with the natural weighting, resulting the beam size of 1.02" x 0.77" (Wide) and 1.00" x 0.75" (Deep). To avoid missing any strongly lensed (~distorted) objects, we also produced a lower-resolution map and cube by applying a uv-taper parameter of 1.5" x 1.5".
The properties of our ALMA maps and cubes are summarized in Table 2, Figure 3, and Figure 4 of Fujimoto et al. 2023.
