The undiscovered ultra-diffuse galaxies of the Local Group
Oliver Newton, Arianna Di Cintio, Salvador Cardona-Barrero +6
Ultra-diffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are difficult to detect beca…
A probabilistic deep learning model to distinguish cusps and cores in dwarf galaxies
J. Expósito-Márquez, C. B. Brook, M. Huertas-Company +4
Numerical simulations within a cold dark matter (DM) cosmology form halos whose density profiles have a steep inner slope (`cusp'), yet observations of galaxies often point towards…
Metallicity profiles of Ultra Diffuse Galaxies in NIHAO simulations
S. Cardona-Barrero, A. Di Cintio, G. Battaglia +2
Supernovae feedback driven expansion has proven to be a viable mechanism to explain the average properties of Ultra Diffuse Galaxies (UDGs) such as the sizes, colors, mass and inte…
A rumble in the dark: signatures of self-interacting dark matter in Super-Massive Black Hole dynamics and galaxy density profiles
Arianna Di Cintio, Michael Tremmel, Fabio Governato +5
We explore for the first time the effect of self-interacting dark matter (SIDM) on the dark matter (DM) and baryonic distribution in massive galaxies formed in hydrodynamical cosmo…
NIHAO XI: Formation of Ultra-Diffuse Galaxies by outflows
Arianna Di Cintio, Chris B. Brook, Aaron A. Dutton +3
We address the origin of Ultra-Diffuse Galaxies (UDGs), which have stellar masses typical of dwarf galaxies but effective radii of Milky Way-sized objects. Their formation mechanis…
Testing Feedback-Modified Dark Matter Haloes with Galaxy Rotation Curves: Estimation of Halo Parameters and Consistency with CDM
Harley Katz, Federico Lelli, Stacy S. McGaugh +3
Cosmological -body simulations predict dark matter (DM) haloes with steep central cusps (e.g. NFW, Navarro et al. 1996). This contradicts observations of gas kinematics in low-m…
