PRFM-vol is a new subgrid star formation model for cosmological simulations that computes SFR from ambient densities via PRFM theory and a modified effective EOS, producing taller stellar scale heights, slightly higher stellar mass, and morphology changes including Toomre-driven clumps compared to p
Composite time-delay lens modelling of JWST WFI2033–4723 yields intermediate stellar IMF normalisation and a steep gNFW inner slope γ_in≃1.3 that is robust to the choice of external cosmology.
Forecasts indicate CSST can detect wide binaries in Segue 1 down to fb ~ 0.01 with 2300 stars but needs 6000 stars and fb ~ 0.1 to distinguish cusped from cored dark matter profiles.
Simulations indicate LISA could statistically distinguish CDM from SIDM (constant 1 cm²/g cross-section) with at least ~70 high-SNR massive black hole merger detections.
Derivative test on SPARC galaxies shows outer rotation curves are consistent with flat profiles rather than Keplerian taper.
