MINERVA

Wed, 17 Jan 2024 00:51:36 +0000

The JWST MINERVA Treasury survey adds additional medium-band and mid-infrared photometry to the UDS, COSMOS, EGS, and GOODS-N legacy fields. Supplemented with existing surveys, MINERVA photometry covers >20 photometric filters, dramatically improving photometric redshifts and SED modeling capabilities. I am the MINERVA NIRCam catalog lead: I utilize the Aperpy aperture photometry pipeline to build high-quality, PSF-homogenized photometric catalogs. DR0 catalogs, which cover the first epoch of MINERVA observations in UDS, are available on the MINERVA website. A full data release is planned for early 2027.

PRIMER

Wed, 17 Jan 2024 00:51:36 +0000

The JWST PRIMER Treasury survey is a 378 sq. arcmin. survey covering the COSMOS and UDS legacy fields down to 28 ABmag in F200W. PRIMER provides NIRCam observations in F090W, F115W, F150W, F200W, F277W, F356W, F410M, and F444W, supplemented by archival HST WFC3 and ACS data. As a member of the PRIMER team, I have been utilizing the aperpy aperture photometry pipeline to build high-quality, PSF-homogenized photometric catalogs. Currently, catalogs for the v7 (July 2023) mosaics from DJA are prepared. These are available by request and subsequent approval from the PRIMER team.

UNCOVER

Wed, 17 Jan 2024 00:51:36 +0000

The JWST UNCOVER Treasury survey is a 45 sq. arcmin. survey covering the Abell 2744 lensing cluster (in combination with GLASS and DDT data). UNCOVER is the deepest-to-date publicly available survey, reaching fainter than 29 ABmag without corrections for lensing. Between UNCOVER and other public NIRCam data, Abell 2744 is covered by observations in F090W, F115W, F150W, F200W, F277W, F356W, F410M, and F444W, supplemented by archival HST WFC3 and ACS data. As a survey builder in the UNCOVER team, I have been involved in the development of the aperpy aperture photometry pipeline, which we use to produce a high-quality, PSF-homogenized photometric catalog for all space-based data covering Abell 2744 (Weaver et al. 2024). Specifically, I am primarily involved in empirical PSF generation via stacked, unsaturated stars and homogenization to a common PSF utilizing regularization.

3D-DASH

Wed, 26 Oct 2022 00:51:36 +0000

3D-DASH is the follow-up program to COSMOS-DASH, extending the total area to 1.43 sq. deg. in HST WFC3/F160W, making it the largest survey done by HST in the near-IR. 3D-DASH imaging and related tools are available on the 3D-DASH MAST page.

HLF GOODS-N Photometric Catalog

Wed, 26 Oct 2022 00:51:36 +0000

Using the Aperpy code, I built a robust photometric catalog from Hubble Legacy Field GOODS-N imaging. The catalog will contain psf-matched aperture photometry from 11 HST bands from the UV to near-IR. Detailed information on the catalog creation process can be found for the HLF GOODS-S Photometric Catalog.

COSMOS-DASH

Wed, 01 Dec 2021 00:51:36 +0000

Hubble Space Telescope (HST) resolution is crucial in measuring the structural properties of high-redshift or blended galaxies. However, large area surveys are traditionally observationally expensive to obtain with HST, especially in the near-infrared. The COSMOS-DASH survey utilizes the novel “Drift And SHift” (DASH) technique to efficiently observe up to eight pointings in a single orbit using HST. This is done by guiding with gyros alone (i.e. diabling fine guidance sensors after the first pointing), which allows for wide-area surveys in the NIR with HST resolution, including the 0.49 square degree COSMOS-DASH survey. I lead the creation of the COSMOS-DASH morphological catalog, which provides structural parameters for over 50,000 galaxies with an increased number of massive galaxies.

The COSMOS-DASH mosaics and morphological catalog, along with a more detailed description of the program are available on the COSMOS-DASH MAST page.
