COSMOS-Web builds on the rich heritage of multiwavelength observations and data products available in the COSMOS field, and will contain about a million galaxies across cosmic time.

COSMOS-Web was the largest General Observer program selected for Cycle 1 of the James Webb Space Telescope (JWST). The survey mapped 0.54 square degrees of the sky (about the area of three full moons) with the Near Infrared Camera (NIRCam) and ...

March 8, 2023 - Abstract:We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hour treasury program conducted by the James Webb Space Telescope in its first cycle of observations.

August 21, 2023 - We present the survey design, ... cycle of observations. COSMOS-Web is a contiguous 0.54 deg2 NIRCam imaging survey in four filters (F115W, F150W, F277W, and F444W) that will reach 5σ point-source depths ranging ∼27.5–28.2 mag....

COSMOS-Web is the largest contiguous area survey to be mapped by the James Webb Space Telescope (JWST) in Cycle 1, covering a contiguous 0.6 deg2 area with deep NIRCam imaging in four filters (F115W, F150W, F277W, and F444W) and a total 0.2 ...

We propose the COSMOS-Webb Survey, an ambitious treasury program to map a contiguous 0.6 deg^2 area with deep NIRCam imaging in 4 filters and a 0.2 deg^2 deep MIRI survey in parallel.

COSMOS-Web provides the most expansive and deepest observations of the universe to date. Now, the team behind this work - which includes several members from The University of Texas at Austin - has released the data and images associated with its full survey, all processed and ready for analysis (see images, specifically, here).

COSMOS-Web (PID: 1727) is a 255 hour wide-field Cycle 1 JWST treasury program that maps a contiguous 0.6 deg2 area with deep NIRCam imaging in 4 filters (F115W, F150W, F277W, and F444W) and a non-contiguous 0.2 deg2 area with MIRI in parallel.

We present the survey design, ... COSMOS-Web is a contiguous 0.54 deg2 NIRCam imaging survey in four filters (F115W, F150W, F277W, and F444W) that will reach 5σ point-source depths ranging ~27.5-28.2 mag....

August 29, 2025 - When NASA’s James Webb Space Telescope begins science operations in 2022, one of its first tasks will be an ambitious program to map the earliest structures in the universe. Called COSMOS-Webb, this wide and deep survey of half-a-million galaxies ...

May 5, 2025 - The COSMOS-Web survey (renamed from COSMOS-Webb, as it will survey a portion of the cosmic web) will map 0.6 square degrees of the sky — about the area of three full Moons — using the James Webb Space Telescope’s Near Infrared Camera (NIRCam) instrument, while simultaneously mapping a smaller 0.2 square degrees with the Mid Infrared Instrument (MIRI).

We present the COSMOS-Web survey, the largest contiguous area survey to be mapped by the James Webb Space Telescope (JWST) in Cycle 1. In 218 hours, COSMOS-Web will map a contiguous 0.6 deg2 area with deep NIRCam imaging in four filters (F115W, ...

September 16, 2025 - We name this the COSMOS-Web Lens Survey (COWLS), which stands out among lens surveys due to several unique characteristics that shape its primary scientific goals. The exceptional survey depth allows the lensed source population to extend beyond ...

June 7, 2024 - COSMOS-Web is a contiguous 0.54 deg2 NIRCam imaging survey in four filters (F115W, F150W, F277W, and F444W) that will reach 5σ point source depths ranging ∼27.5-28.2 magnitudes.

Abstract • We present the survey ... COSMOS-Web is a contiguous 0.54 deg2 NIRCam imaging survey in four filters (F115W, F150W, F277W, and F444W) that will reach 5σ point-source depths ranging ~27.5-28.2 mag....

September 4, 2025 - Abstract:We present the COSMOS-Web Lens Survey (COWLS), a sample of over 100 strong lens candidates from the $0.54$\,deg$^2$ COSMOS-Web survey, discovered using exquisite James Webb Space Telescope (JWST) imaging across four wavebands.

The plot below shows the final ... survey. The depths quoted are the measured flux in a 3 arc-second aperture. (Click on image to enlarge) All COSMOS data can be found in the public/private COSMOS Archive. Direct links to particular data sets are also given to the right of each data set description on this website...

March 27, 2025 - We compare forecasts for the abundance and properties of strong gravitational lenses in the COSMOS-Web survey, a $0.54$ deg$^2$ survey of the COSMOS field using the NIRCam and MIRI instruments aboard JWST, with the first catalogue of strong lens candidates identified in the observed NIRCam data, COWLS.

The COSMOS-Web project, conducted by the James Webb Space Telescope (JWST), aims to build on the legacy of COSMOS with a 255-hour treasury program. This survey will cover a 0.54 square degree area with NIRCam imaging in four filters and MIRI ...
