Severe gas expulsion and expansion in a primordial star cluster, combined with a top-heavy IMF, can reproduce the high velocity dispersion and broad stream of C-19 without dark matter subhalos.
3D simulations show gas can vault over nuclear rings in barred galaxies via vertical momentum, delivering outer gas to the central region.
300S stellar stream exhibits three density peaks, smooth width variations, a possible 4.7 degree gap, and a kink modeled as resulting from Large Magellanic Cloud interaction across its full known footprint.
MOG produces distinct orbital precession and sky-projected deviations for S-stars that grow with the parameter α and can resemble dark matter effects while remaining testable against GR.
Simulations of the Aquila Rift show uneven clumps accreting gas and merging along filaments to form a fractal cluster whose velocity anisotropies, rotation, and expansion record the assembly history even after gas removal.
Simulations show stars at the edges of stellar streams are more likely to retain unperturbed planetary systems than stars near the stream center.
Young star clusters in the NGC 628 simulation inherit a filament mass power-law index of -1.35 at formation via gravitational fragmentation and evolve to -1.55 after 60 Myr.
Bayesian comparison of Gaia DR3 rotation curves favors the Einasto dark matter profile over NFW, prefers cored over cuspy profiles, and finds MOND variants provide poorer fits than the best dark matter models.
