Galactic tides and the outer density profile of the Sculptor and Ursa Minor dwarf spheroidals
Daniel A. Boyea, Julio F. Navarro, Jaclyn Jensen +1
Most dwarf spheroidal (dSph) satellites of the Milky Way follow exponential surface density profiles that decline sharply in the outer regions. The Sculptor (Scl) and Ursa Minor (U…
The abundance and radial distribution of faint and ultra-faint dwarfs in galaxy clusters
Pradyumna Sadhu, Laura V. Sales, Julio F. Navarro +3
Cosmological simulations of galaxy clusters are unable to resolve dwarf galaxies due to limited numerical resolution which drives the artificial disruption of dark matter substruct…
The missing ultra-faint satellites of the Milky Way
Isabel M. E. Santos-Santos, Carlos S. Frenk, Julio F. Navarro
We combine the highest resolution N-body simulation of a CDM halo (Aquarius-A) with the semi-analytic model GALFORM to study the full satellite population o…
Cored galaxies in cuspy dark matter halos
Fernando Valenciano, Jorge Martin Camalich, Arianna Di Cintio +4
We investigate constraints on the inner stellar density profile from photometric data of dwarf spheroidal and ultra-faint dwarf galaxies. Our aim is to clarify under what condition…
Accreted stars and stellar haloes of simulated galaxies in TNG50
Bruno M. Celiz, Julio F. Navarro, Mario G. Abadi
We use the TNG50 cosmological hydrodynamic simulation to study the accreted stellar component and stellar haloes of isolated galaxies spanning a wide range of masses ($10^8<M_*/M_\…
Impulsive mixing of stellar populations in dwarf spheroidal galaxies
Raphaël Errani, Matthew G. Walker, Simon Rozier +2
We study the response of mono-energetic stellar populations with initially isotropic kinematics to impulsive and adiabatic changes to an underlying dark matter potential. Half-ligh…
The unabridged satellite luminosity function of Milky Way-like galaxies in CDM: the contribution of "orphan" satellites
Isabel Santos-Santos, Carlos Frenk, Julio Navarro +2
We study the abundance, radial distribution, and orbits of luminous satellites in simulations of MW-mass dark halos in the LCDM cosmology. We follow the evolution of a halo from th…
Star formation beyond galaxies: widespread in-situ formation of intra-cluster stars
Niusha Ahvazi, Laura V. Sales, Julio F. Navarro +3
We study the fraction of the intra-cluster light (ICL) formed in-situ in the three most massive clusters of the TNG50 simulation, with virial masses M. We…
Micro galaxies in LCDM
Raphaël Errani, Rodrigo Ibata, Julio F. Navarro +2
A fundamental prediction of the Lambda Cold Dark Matter (LCDM) cosmology is the centrally divergent cuspy density profile of dark matter haloes. Density cusps render CDM haloes res…
Imposters among us: globular cluster kinematics and the halo mass of ultra-diffuse galaxies in clusters
Jessica E. Doppel, Laura V. Sales, José A. Benavides +4
The velocity dispersion of globular clusters (GCs) around ultra-diffuse galaxies (UDGs) in the Virgo cluster spans a wide range, including cases where GC kinematics suggest halos a…
Satellites of Simulated Galaxies: survival, merging, and their relation to the dark and stellar halos
L. V. Sales, J. F. Navarro, M. G. Abadi +1
We study the population of satellite galaxies formed in a suite of N-body/gasdynamical simulations of galaxy formation in a LCDM universe. We find little spatial or kinematic bias…
