Galactic tides and the Crater II dwarf spheroidal: a challenge to LCDM?
Alexandra Borukhovetskaya, Julio F. Navarro, Raphael Errani +1
The unusually low velocity dispersion and large size of Crater II pose a challenge to our understanding of dwarf galaxies in the Lambda Cold Dark Matter (LCDM) cosmogony. The low v…
Structure and kinematics of tidally limited satellite galaxies in LCDM
Raphaël Errani, Julio F. Navarro, Rodrigo Ibata +1
We use N-body simulations to model the tidal evolution of dark matter-dominated dwarf spheroidal galaxies embedded in cuspy Navarro-Frenk-White subhalos. Tides gradually peel off s…
The tidal evolution of the Fornax dwarf spheroidal and its globular clusters
Alexandra Borukhovetskaya, Raphael Errani, Julio F. Navarro +2
The dark matter (DM) content of the Fornax dwarf spheroidal galaxy inferred from its kinematics is substantially lower than expected from LCDM cosmological simulations. We use N-bo…
