Star clusters forming in cosmic filaments at z≈7.6 are systematically slow rotators, and a gas-rich subset overlaps the kinematic and density locus of Milky Way globular clusters, making them plausible proto-globular clusters.

JWST data on LRDs and LBDs show AGN-like excitation, strong Lyα with broad components, and X-ray weakness, implying clumpy or equatorial geometries around growing black holes rather than complete gas envelopes.
Two high-redshift galaxy candidates are reidentified as ultra-cool Y-type brown dwarfs at ~500 pc based on NIRSpec spectra matching templates and detected proper motions of 49 and 24 mas/yr.
A bias-controlled quasar sample of ~2000 objects demonstrates that the X-ray-to-UV luminosity relation remains constant from redshift 0.7 to 5.
Renaissance Simulations produce galaxies at z>10 whose stellar masses, star formation rates, sizes, and colors overlap with JWST observations while extending to lower masses.
A sparse population of primordial charged compact objects is hypothesized with specific parameters and shown to face severe plasma-screening and neutralization constraints while failing to produce late-time acceleration in the homogeneous FLRW approximation.
Small-scale power spectrum boosts alter ionization morphology enough that 21 cm power spectra and bubble sizes remain distinguishable from Lambda CDM under current constraints, offering SKA a probe for such deviations.

Probing power spectrum enhancement at small scales with the SKA
Small-scale power spectrum boosts alter ionization morphology enough that 21 cm power spectra and bubble sizes remain distinguishable from Lambda CDM under current constraints, offering SKA a probe for such deviations.
