abstract
Stellar population synthesis (SPS) provides the link between the stellar and dust content of galaxies and their observed spectral energy distributions. In the present work we perform a comprehensive calibration of our own flexible SPS (FSPS) model against a suite of data. Several public SPS models are intercompared, including the models of Bruzual & Charlot (BC03), Maraston (M05) and FSPS. The relative strengths and weaknesses of these models are evaluated, with the following conclusions: 1) The FSPS and BC03 models compare favorably with MC data at all ages, whereas M05 colors are too red and the age-dependence is incorrect; 2) All models yield similar optical and near-IR colors for old metal-poor systems, and yet they all provide poor fits to the integrated J-K and V-K colors of both MW and M31 star clusters; 4) All models predict ugr colors too red, D4000 strengths too strong and Hdelta strengths too weak compared to massive red sequence galaxies, under the assumption that such galaxies are composed solely of old metal-rich stars; 5) FSPS and, to a lesser extent, BC03 can reproduce the optical and near-IR colors of post-starburst galaxies, while M05 cannot. Reasons for these discrepancies are explored. The failure at predicting the ugr colors, D4000, and Hdelta strengths can be explained by some combination of a minority population of metal-poor stars, young stars, blue straggler and/or blue horizontal branch stars, but not by appealing to inadequacies in either theoretical stellar atmospheres or canonical evolutionary phases (e.g., the main sequence turn-off). We emphasize that due to a lack of calibrating star cluster data in regions of the metallicity-age plane relevant for galaxies, all of these models continue to suffer from serious uncertainties that are difficult to quantify.

A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.
JWST spectroscopy of 295 galaxies at 5.5 < z < 14.3 shows UV slope beta reddening at z > 9.5, with lack of dust as the main driver of bluer values and nebular continuum at T > 15,000 K able to reproduce the observed range without dust.
Resolved gas and dust maps in a z=2 quiescent galaxy reveal accreted material from tidal interactions and a past star-formation rejuvenation, indicating that gas content variations are not solely due to consumption timescales.
A JWST census detects neutral ISM absorption in 76 of 309 galaxies at 0.6<z<4 and outflows in 26, indicating AGN-driven neutral outflows dominate in quiescent systems at cosmic noon.
Little Red Dots show soft ionizing spectra consistent with massive stars, based on high H-alpha EWs and low HeII/H-beta ratios that rule out hard AGN spectra via Cloudy modeling.
Progenitor age is the primary physical driver of the host-mass and host-sSFR magnitude steps in Type Ia supernovae, with the mass step eliminated by direct age correction.
TNG50 shows galactic outflow mass loading is non-monotonic with stellar mass, rising rapidly above 10^10.5 Msun due to black hole feedback, and produces fast multi-phase outflows with emergent collimation.
Accreting X-ray sources cannot supply enough EUV photons to account for He III regions in metal-poor star-forming dwarf galaxies.
Milky Way abundance trends act as effective empirical proxies for nucleosynthetic yields, recovering alpha and Fe-peak abundances in quiescent galaxies with 0.05 dex median offset versus 0.23 dex for theory, indicating largely universal yields.
JWST data show massive quiescent galaxies in high-redshift proto-clusters formed and quenched simultaneously, with AGN signatures, indicating environmental triggering of quenching.
Discovery of a gravitationally lensed Type II supernova at z=1.37 with magnification ≳100×, confirmed via multi-telescope spectra and imaging.
Star formation histories inferred for z=2-5 massive quiescent galaxies imply past number densities that align with observed rapid evolution since z~7.
Spatially-resolved spectroscopy detects AGNs in 4-9% of low-mass galaxies, higher than single-fiber rates because it catches extended emission missed by central-point observations.
Abundant early heavy seeds plus frequent mergers produce the massive black holes seen by JWST at z>9 and yield about four LISA events per year at z>=8.
JADES DR5 delivers a public catalog of Bayesian-inferred stellar masses, SFRs, SFHs, dust, metallicities, and AGN contributions for ~500k galaxies via Prospector with an evolving SFMS prior.
Eruptive mass loss in red supergiants increases linearly with metallicity, calibrated via by-eye fits to Local Group luminosity functions, preventing initial masses above about 20 solar masses from reaching the red supergiant phase.
Ca-rich gap transients and 91bg-like SNe occupy similar massive quiescent host parameter space with peak delay times around 10^4 Myr, unlike normal Type Ia (~10^3 Myr) and Type II (~10 Myr) SNe.
Massive quiescent galaxies at cosmic noon are compact and bulge-dominated with inside-out quenching, where inner regions formed stars ~0.5 Gyr earlier and quenched faster than outskirts.
COLIBRE simulations with SKIRT post-processing match observed galaxy luminosity functions from FUV to submm at z=0, except underpredicting bright mid-IR galaxies.
Massive quiescent galaxies at high redshifts show elevated fractions in small-scale overdensities, indicating environmental quenching via galaxy interactions plays a major role.
Simulations of high-redshift galaxies show the 1719 Å UV index reliably traces stellar metallicity while others are more sensitive to star formation history.
New measurement of the Hubble parameter H(z=0.12) = 71.33 ± 4.20 km s^{-1} Mpc^{-1} obtained from cosmology-independent stellar ages of passive galaxies in DESI Data Release 1.
Hα luminosity functions at z~1.3 and z~2.0 yield faint-end slopes of -1.50 and -1.60, with integrated SFR densities of 0.097 and 0.129 M⊙ yr⁻¹ Mpc⁻³ from a sample of 99 emitters.
