The Tail of Late-forming Dwarf Galaxies in CDM
Alejandro Benitez-Llambay, Michele Fumagalli
We use a robust analytical model together with a high-resolution hydrodynamical cosmological simulation to demonstrate that in a cold dark matter (CDM) universe, a small fra…
The detailed structure and the onset of galaxy formation in low-mass gaseous dark matter haloes
Alejandro Benitez-Llambay, Carlos Frenk
We present a model for the formation of the first galaxies before and after the reionization of hydrogen in the early universe. In this model, galaxy formation can only take place…
Cusp or core? Revisiting the globular cluster timing problem in Fornax
Noah Meadows, Julio F. Navarro, Isabel Santos-Santos +2
We use N-body simulations to revisit the globular cluster (GC) ``timing problem'' in the Fornax dwarf spheroidal (dSph). In agreement with earlier work, we find that, due to dynami…
To beta or not to beta: can higher-order Jeans analysis break the mass-anisotropy degeneracy in simulated dwarfs?
Anna Genina, Justin I. Read, Carlos S. Frenk +6
We test a non-parametric higher-order Jeans analysis method, GravSphere, on 32 simulated dwarf galaxies comparable to classical Local Group dwarfs like Fornax. The galaxies are sel…
Baryonic clues to the puzzling diversity of dwarf galaxy rotation curves
Isabel M. E. Santos-Santos, Julio F. Navarro, Andrew Robertson +7
We use a compilation of disc galaxy rotation curves to assess the role of the luminous component ("baryons") in the rotation curve diversity problem. As in earlier work, we find th…
The Milky Way total mass profile as inferred from Gaia DR2
Marius Cautun, Alejandro Benitez-Llambay, Alis J. Deason +7
We determine the Milky Way (MW) mass profile inferred from fitting physically motivated models to the Gaia DR2 Galactic rotation curve and other data. Using various hydrodynamical…
