Dark matter constraints from dwarf galaxies with data-driven J-factors
Alexandre Alvarez, Francesca Calore, Anna Genina +3
We present an updated analysis of the gamma-ray flux from the directions of classical dwarf spheroidal galaxies, deriving new constraints on WIMP dark matter (DM) annihilation usin…
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…
The distinct stellar metallicity populations of simulated Local Group dwarfs
Anna Genina, Carlos S. Frenk, Alejandro Benitez-Llambay +4
A number of Local Group dwarf galaxies are known to have two spatially segregated stellar metallicity populations, a centrally concentrated metal-rich population and a more extende…
The core-cusp problem: a matter of perspective
Anna Genina, Alejandro Benitez-Llambay, Carlos S. Frenk +6
The existence of two kinematically and chemically distinct stellar subpopulations in the Sculptor and Fornax dwarf galaxies offers the opportunity to constrain the density profile…
