SIDM halos accelerate bar formation and growth in disk galaxies through enhanced angular momentum exchange, independent of core formation.
Information-theoretic analysis of TNG50 simulations finds high mutual information (0.4-0.8) between bar and spiral parameters and comparable transfer entropy (0.33-0.42) in both directions, indicating mutual co-regulation.
SHAMe-SF modeling of small-scale DESI ELG clustering delivers 6% precision on σ8 and Ωm h², matching full DR1 results with 1% volume.
Barred galaxies transition from actively star-forming at z~1-2 to quiescent at z~0, with the fraction of quiescent galaxies hosting bars increasing steeply over cosmic time.
Proposes that 10 years of 0.5 μas astrometry of Proxima Centauri can distinguish MOND from Newtonian gravity in the low-acceleration regime.
GREX-PLUS is a proposed JAXA L-class mission with a 1m cooled telescope, wide-field 2-8um camera, and R=30000 spectrometer in 10-18um to enable studies of z>15 galaxies, protoplanetary snowlines, and related astrophysics.
A review summarizing detection methods, population statistics, and coevolution of supermassive black holes with host galaxies from early universe observations and simulations.
