Implications for Galaxy Formation Models from Observations of Globular Clusters around Ultra-Diffuse Galaxies
Teymoor Saifollahi, Dennis Zaritsky, Ignacio Trujillo +5
We present an analysis of Hubble Space Telescope observations of globular clusters (GCs) in six ultra-diffuse galaxies (UDGs) in the Coma cluster, a sample that represents UDGs wit…
Systematic errors induced by the elliptical power-law model in galaxy-galaxy strong lens modeling
Xiaoyue Cao, Ran Li, J. W. Nightingale +9
The elliptical power-law (EPL) model of the mass in a galaxy is widely used in strong gravitational lensing analyses. However, the distribution of mass in real galaxies is more com…
Dwarf stellar haloes: a powerful probe of small-scale galaxy formation and the nature of dark matter
Alis J. Deason, Sownak Bose, Azadeh Fattahi +3
We use N-body cosmological simulations and empirical galaxy models to study the merger history of dwarf-mass galaxies (with M_halo~10^10 M_Sun). Our input galaxy models describe th…
Giant cold satellites from low-concentration haloes
Nicola C. Amorisco
The dwarf satellite galaxies of the Milky Way Crater II and Antlia II have uncommonly low dynamical mass densities, due to their large size and low velocity dispersion. Previous wo…
First constraints on Fuzzy Dark Matter from the dynamics of stellar streams in the Milky Way
Nicola C. Amorisco, A. Loeb
We present a novel method to constrain the mass of ultra-light bosons as the dark matter using stellar streams formed by disrupting Globular Clusters in the Milky Way. The turbulen…
Globular cluster populations and the kinematical fingerprints of minor mergers
Nicola C. Amorisco
We use Monte Carlo CDM assembly histories, minor-merger N-body simulations and empirical relations between halo mass and the globular cluster (GC) abundance to study the kinemat…
