LRD host galaxies show average metallicity 0.08 Z_sun with narrow stable range, challenging pristine-gas formation models while ruling out typical local AGN.
Simulation study proposes that weakly rotating, gas-rich cosmic wallflowers at high redshift are natural proto-globular cluster candidates based on kinematics and densities.
Stellar streams encode the initial mass function of globular clusters, recovered as a declining power-law with slope 1.3 for streams above 1000 solar masses.
Lumen modeling of IllustrisTNG50 shows that high ionization parameters from massive star clusters plus enhanced nitrogen abundances are needed to reproduce the extreme [OIII]/Hβ, [OIII]/[OII], and [NII]/Hα ratios seen in z>3 galaxies.
JWST observations identify all massive young embedded star clusters in the Antennae, revealing they are extremely young, heavily obscured, and account for ~60% of the ionizing luminosity.
N-body simulations show high-z proto-star clusters with multiple populations can survive strong early tidal fields and evolve into systems with properties matching Galactic globular clusters after 12 Gyr.
AuriGLOBES is a new subgrid model implemented in Auriga simulations that incorporates compressive tides and compact-object mass loss to transform an initial Schechter mass function into observed globular cluster populations while reproducing the GC system mass-halo mass relation.
High-resolution zoom-in simulation of a z~10 galaxy produces over 10^5 star clusters with scale-free mass function, 90% of star formation in clusters, global SFE 0.2-0.3, and reproduces JWST super-bright galaxies via feedback-free bursts.
Hybrid hydro/direct N-body simulations of dense high-redshift gas clouds form very massive stars via runaway collisions that collapse to IMBHs capable of growing from ~6700 to ~62000 solar masses in 100 Myr under optimistic assumptions.
N-body simulations demonstrate runaway GW BBH mergers in dense BH clusters (≥5×10^9 M⊙/pc³) produce ~10³ M⊙ IMBHs within 10 Myr.
Reconstruction of GCIMF from present-day systems via environment-dependent mass-loss inversion yields power-law high-mass ends whose slopes correlate with host halo mass.
Using lensed JWST data behind Abell S1063, the UVLF at z~6-11 is fit with gradual quadratic turnover, yielding no evidence for turnover to M_UV=-13.5 at z=6, exclusion limits on turnover models, and lower bounds showing faint galaxies contribute >50% of UV luminosity density and ~64% of ionizing pho
Identification of a strongly lensed ultra-faint galaxy at z≈10 with F200W excess, interpreted via SED modeling as either an extremely metal-poor stellar population or a young high-ionization system with emission lines.
JWST observations of lensed galaxies yield tentative evidence for mass- and redshift-dependent radial gradients in nebular dust attenuation, with lower attenuation at higher redshifts and more extended SFR profiles in lower-redshift massive systems consistent with inside-out growth.
Clumpy galaxies at cosmic noon show systematically lower metallicities than the mass-metallicity relation, with clump properties indicating metal-poor gas accretion as the driver rather than mergers.
BonFIRE and CampFIRE simulations show bursty clustered star formation in early galaxies and predict UV luminosity functions matching observations at faint magnitudes with a turnover at M_UV approx -14 but overpredicting brighter galaxies.
LRDs require Compton-thick gas at moderate metallicity plus high accretion rates producing weak X-rays to explain their non-detection, implying they are not chemically pristine.
JADES DR5 delivers 2081 z_phot > 8 galaxy candidates with UV slope trends, morphological evidence of clumpy growth, and improved photo-z methods tested on a spectroscopic subsample.
N-body models of young and old dense star clusters show BBH mergers span primary masses from ~6 to >100 solar masses with a peak near 8 solar masses, reproducing the LIGO-inferred distribution, with low-mass mergers mostly from metal-rich clusters.
SKA-Mid is predicted to yield samples of 10-100 low-metallicity Lyman continuum emitting galaxies per square degree, enabling multi-wavelength studies of feedback processes linked to ionizing photon escape.
New SBF distance confirms NGC5846_UDG1 lies in the NGC 5846 group and reconciles prior GC counts to ~50 members, supporting a massive dark matter halo.
Presents strong lensing models and mass measurements for 14 clusters (z=0.25-1.06) based on JWST data, with new lensed systems and public data release.
