I have made a few open source projects for help with JWST and JADES.
NIFTY, Near-Infrared Fitting for T and Y Dwarfs, was designed to fit JWST NIRCam/MIRI photometry or NIRSpec prism spectroscopy of cold brown dwarf candidates with the LOWZ (Meisner et al. 2021), ATMO2020 (Phillips et al. 2020), Sonora Elf Owl v2 (Mukherjee et al. 2024, Wogan et al. 2025), or earlier Sonora Elf Owl (with PH3, Beiler et al. 2024) atmospheric models, using a Bayesian framework with the emcee sampler. This code was described in Hainline et al. (2026).
Visualizer of JADES images/cutouts along with SED fits for individual objects.
Code for taking the JAGUAR Mock Catalog and preparing it for photo-z analysis.
JADES Extragalactic Ultra-deep Artificial Realization (JAGUAR) is a new empirical model of the evolution of galaxy properties driven entirely by observations over the redshift range 0.2 < z < 10 (Williams et al. 2018). Using this model we have built a suite of mock galaxy catalogs designed for the new era of extragalactic deep field surveys using the James Webb Space Telescope (JWST), including realistic extrapolations to z < 15 and down to the expected JWST detection limits.
