D-CAF simulations show that ongoing gas collapse during star formation shortens stellar crossing times, rendering gas expulsion more adiabatic and thereby regulating the survival and expansion rates of young stellar systems.
Lyα radiation pressure mildly reduces gas-to-star conversion efficiency in dense high-redshift clusters while dominating the launch of rapid outflows.
A new scale-aware diagnostic framework shows that unconstrained diffusion generative models exhibit structural freezing and instability instead of smooth physical responses under multiscale perturbations.
ALMA CO observations of NGC 4565 reveal a thin non-flaring molecular disk with a central gap, consistent GMC properties to 17 kpc, and a prominent star-forming ring feature.
Bursty stellar feedback produces systematically flatter metallicity gradients than smooth feedback in high-redshift galaxies across multiple simulation suites.
SED fitting of star clusters in NGC 628 identifies an evolutionary sequence from embedded young clusters to visible ones with a photo-dissociation region clearing timescale of approximately 4 Myr.
Kpc-resolution ALMA CO and dust maps of three z~3 dusty galaxies are consistent with gravo-turbulent star-formation models rather than non-turbulent predictions.
MST analysis of CMZoom data finds mass segregation in 5 of 17 CMZ clouds, inverse segregation or none in the rest, and no clear link to evolutionary stage or star-formation activity.
Multi-wavelength observations identify a compact hub-filament system in G286.21+0.17 whose core properties follow steep radial power laws consistent with competitive accretion.
Four controlled identical realizations of a galaxy-cluster zoom-in simulation reveal 10-25% variability in galaxy masses driven by stochastic processes and modulated by feedback, establishing a noise-dominated but statistically reproducible regime at low resolution.
Review of MHD numerical methods for star formation, covering discretization techniques, divergence-free constraints, sink particles, and non-ideal effects like diffusion and the Hall effect.
