Simulating JWST/NIRCam Color Selection of High-Redshift Galaxies

Understand

The NIRCam instrument on the upcoming James Webb Space Telescope (JWST) will offer an unprecedented view of the most distant galaxies.

• In preparation for future deep NIRCam extragalactic surveys, it is crucial to understand the color selection of high-redshift galaxies using the Lyman dropout technique.
• To that end, we have used the JAdes extraGalactic Ultradeep Artificial Realizations (JAGUAR) mock catalog to simulate a series of extragalactic surveys with realistic noise estimates.
• This enables us to explore different color selections and their impact on the number density of recovered high-redshift galaxies and lower-redshift interlopers.
