We use the galaxy rotation curves in the SPARC database to compare nine different dark matter (DM) and modified gravity models on an equal footing, paying special attention to the stellar mass-to-light ratios. We compare three noninteracting DM models: a self-interacting DM model, two hadronically interacting DM models, and three modified Newtonian dynamics type models, modified Newtonian dynamics (MOND), a radial acceleration relation, and a maximal-disk model. The models with DM–gas…
Testing multiflavored ULDM models with SPARC

We perform maximum likelihood estimates (MLEs) for single and double ﬂavor ultralight dark matter (ULDM) models using the Spitzer Photometry and Accurate Rotation Curves (SPARC) database. These
A Stable Sexaquark: Overview and Discovery Strategies
The neutral, flavor singlet scalar uuddss bound state – the sexaquark, S – may have a low enough mass to be stable or extremely long-lived. Here we review mass estimates and production expectations
Non-spherical dark matter structures detection
• Physics
• 2022
A rotation curve inequality that holds for spherically symmetric mass distributions is derived, and tested against the SPARC galaxy rotation curves dataset. We identify several Galaxies, e.g. NGC7793
