This paper gives an overview of TEMPLATES, a JWST Early Release Science program that targeted four extremely bright, gravitationally lensed galaxies: two extremely dusty, two with low attenuation, as templates for galaxy evolution studies with JWST. TEMPLATES obtains a common set of spectral diagnostics for these 1.3 < z < 4.2 galaxies, in particular H alpha, Paschen alpha, and the rest-frame optical and near-infrared continua. In addition, two of the four targets have JWST coverage of [O III] 5007 Angstrom and H beta; the other two targets have have JWST coverage of PAH 3.3 micron and complementary ALMA data covering the [C II] 158 micron emission line. The science goals of TEMPLATES are to demonstrate attenuation-robust diagnostics of star formation, map the distribution of star formation, compare the young and old stellar populations, and measure the physical conditions of star formation and their spatial variation across the galaxies. In addition, TEMPLATES has technical goals to establish best practices for the Integral Field Units (IFU) within the NIRSpec and MIRI instruments, both in terms of observing strategy and in terms of data reduction. The paper describes TEMPLATES's observing program, scientific and technical goals, data reduction methods, and deliverables, including high-level data products and data reduction cookbooks.

  1. GLIMPSE: An ultra-faint $\simeq$ 10$^{5}$ $M_{\odot}$ Pop III Galaxy Candidate and First Constraints on the Pop III UV Luminosity Function at $z\simeq6-7$

    astro-ph.GA 2025-01 conditional novelty 7.0 of 10

    A JWST search reports an ultra-faint, lensed galaxy at z=6.5 whose SED matches Population III models, giving first constraints on the Pop III UV luminosity function.

  2. Further Evidence for a Direct-Collapse Origin of the Supermassive Black Hole at the Center of the Infinity Galaxy

    astro-ph.GA 2025-06 conditional novelty 6.0 of 10

    New JWST observations show a supermassive black hole between two colliding galaxy nuclei moves within about 50 km/s of the surrounding gas, consistent with in-situ formation in a direct collapse.

  3. Metallicity Scatter Originating from Sub-kiloparsec Starbursting Clumps in the Core of a Protocluster at z=7.88

    astro-ph.GA 2025-01 conditional novelty 6.0 of 10

    Spatially resolved JWST spectroscopy of a z=7.88 merging system reveals up to about 1 dex internal scatter in oxygen abundance, anchored by a direct electron-temperature measurement of 7.4 in one starbursting clump.

    astro-ph.GA 2025-01 conditional novelty 6.0 of 10

    Two SPT clusters are characterized as Frontier-Field-class cosmic telescopes, with z=9 Einstein radii of 42 and 43 arcseconds and lensing-strength areas of 4.93 and 3.64 arcmin^2.
