Potamides: Mapping Dark Matter Halo Shapes from Stellar Stream Tracks in the Local Universe
Sirui Wu, Nathaniel Starkman, Sarah Pearson +3
Stellar streams trace the gravitational potential of their host galaxies and offer a direct probe of dark matter halo geometry. Cosmological simulations predict that halo shapes de…

Total and dark mass from observations of galaxy centers with Machine Learning
Sirui Wu, Nicola R. Napolitano, Crescenzo Tortora +4
The galaxy total mass inside the effective radius encode important information on the dark matter and galaxy evolution model. Total "central" masses can be inferred via galaxy dyna…

The catalogue of virtual early-type galaxies from IllustrisTNG: validation and real observation consistency
Pedro de Araujo Ferreira, Nicola R. Napolitano, Luciano Casarini +3
Early-type galaxies (ETGs) are reference systems to understand galaxy formation and evolution processes. The physics of their formation and internal dynamics are codified in well-k…
