The Pristine survey -- XVII. The C-19 stream is dynamically hot and more extended than previously thought
Zhen Yuan, Nicolas F. Martin, Rodrigo A. Ibata +22
The C-19 stream is the most metal poor stellar system ever discovered, with a mean metallicity . Its low metallicity dispersion ( 0.18 at…
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…
The asymptotic tidal remnants of cold dark matter subhalos
Raphaël Errani, Julio F. Navarro
We use N-body simulations to study the evolution of cuspy cold dark matter (CDM) halos in the gravitational potential of a massive host. Tidal mass losses reshape CDM halos, leavin…
Can tides disrupt cold dark matter subhaloes?
Raphaël Errani, Jorge Peñarrubia
The clumpiness of dark matter on sub-kpc scales is highly sensitive to the tidal evolution and survival of subhaloes. In agreement with previous studies, we show that N-body realis…
The Formation of Ultra Diffuse Galaxies in Cored Dark Matter Halos Through Tidal Stripping and Heating
Timothy Carleton, Raphaël Errani, Michael Cooper +3
We propose that the Ultra-Diffuse Galaxy (UDG) population represents a set of satellite galaxies born in M halos, similar to field dwarfs, which suffe…
Systematics in virial mass estimators for pressure-supported systems
Raphaël Errani, Jorge Peñarrubia, Matthew G. Walker
Mass estimators are a key tool to infer the dark matter content in pressure-supported systems like dwarf spheroidal galaxies (dSphs). We construct an estimator for enclosed masses…
