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…
Off the baryonic Tully-Fisher relation: a population of baryon-dominated ultra-diffuse galaxies
Pavel E. Mancera Piña, Filippo Fraternali, Elizabeth A. K. Adams +17
We study the gas kinematics traced by the 21-cm emission of a sample of six HIrich low surface brightness galaxies classified as ultra-diffuse galaxies (UDGs). Using the 3D kine…
The HI Velocity Function: a test of cosmology or baryon physics?
G. Chauhan, C. D. P. Lagos, D. Obreschkow +3
Accurately predicting the shape of the HI velocity function of galaxies is regarded widely as a fundamental test of any viable dark matter model. Straightforward analyses of cosmol…
The Ophiuchus stream progenitor: a new type of globular cluster and its possible Sagittarius connection
James M. M. Lane, Julio F. Navarro, Azadeh Fattahi +2
The Ophiuchus stream is a short arc-like stellar feature of uncertain origin located kpc North of the Galactic centre. New proper motions from the second data relea…
