We present the Prime Focus Spectrograph (PFS) Galaxy Evolution pillar of the 360-night PFS Subaru Strategic Program. This 130-night program will capitalize on the wide wavelength coverage and massive multiplexing capabilities of PFS to study the evolution of typical galaxies from cosmic dawn to the present. From Lyman alpha emitters at z~7 to probe reionization, drop-outs at z~3 to map the inter-galactic medium in absorption, and a continuum-selected sample at z~1.5, we will chart the physics of galaxy evolution within the evolving cosmic web. This article is dedicated to the memory of Olivier Le Fevre, who was an early advocate for the construction of PFS, and a key early member of the Galaxy Evolution Working Group.

  1. The Role of Cluster Environments in Quiescent Galaxy Stellar Halo Assembly

    astro-ph.GA 2026-04 unverdicted novelty 6.0 of 10

    High-mass quiescent galaxies in clusters assemble more luminous stellar halos than field galaxies while low-mass cluster galaxies assemble less luminous ones over 0.1 < z < 1.

  2. Constraining reionization morphology and source properties with 21cm galaxy cross-correlation surveys

    astro-ph.CO 2026-01 conditional novelty 6.0 of 10

    Simulation-based inference on mock 21cm-galaxy cross-power spectra shows these measurements can tightly constrain neutral fraction, overdensity, and source escape fraction and star-formation efficiency, if redshifts a...

  3. Bridging Simulations and EFT: A Hybrid Model of the Lyman-Alpha Forest Field

    astro-ph.CO 2025-12 conditional novelty 6.0 of 10

    A hybrid EFT forward model using N-body displacements reproduces the simulated Lyman-alpha forest to 5% at k <= 1 h/Mpc with a white-noise residual.

  4. Exploring the Origin of Rejuvenating Gas from MaNGA Nearby Galaxies

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

    Most nearby 'rejuvenating' galaxies — those that restarted star formation within the last ~200 Myr — are fueled by gas already present in the galaxy, not by accreted metal-poor gas; one MaNGA galaxy shows clear extern...

  5. The Compressed 3D Lyman-Alpha Forest Bispectrum

    astro-ph.CO 2025-10 conditional novelty 6.0 of 10

    The Lyman-alpha forest bispectrum can be compressed into 26 skew spectra, including a new shifted variant, with tree-level EFT predictions matching simulations at 1-2 sigma up to k≈0.17 h/Mpc.

  6. SQuIGG$\vec{L}$E: Buried star formation cannot explain the rapidly fading CO(2-1) luminosity in massive, $z\sim0.7$ post-starburst galaxies

    astro-ph.GA 2025-08 conditional novelty 6.0 of 10

    Buried star formation cannot explain the rapid CO fading in z~0.7 post-starburst galaxies, so gas-rich recently quenched galaxies may rejuvenate instead of directly becoming quiescent.

  7. LATIS: Comparing Galaxy and IGM Tomography Maps as Tracers of Large-scale Structure and Protoclusters at $z \sim 2.5$

    astro-ph.GA 2025-07 conditional novelty 6.0 of 10

    At z ~ 2.5, IGM absorption and Lyman-break galaxy density match a simple model almost everywhere, but 4 of the 16 strongest absorption peaks are unusually poor in galaxies, motivating a UV-dim protocluster population.

  8. Galactic Archaeology with the Subaru `\=Onohi`ula Prime Focus Spectrograph Strategic Program

    astro-ph.GA 2026-04 unverdicted novelty 5.5 of 10

    The PFS Galactic Archaeology survey will observe thousands of stars in Local Group systems to measure density profiles in dwarfs and compare assembly histories of M31 and the Milky Way.
