Insights from the Outskirts: Chemical and Dynamical Properties in the outer Parts of the Fornax Dwarf Spheroidal Galaxy
Benjamin Hendricks, Andreas Koch, Matthew Walker +3
We present radial velocities and [Fe/H] abundances for 340 stars in the Fornax dwarf spheroidal from R~16,000 spectra. The targets have been obtained in the outer parts of the gala…
Faint dwarfs as a test of DM models: WDM vs. CDM
Fabio Governato, Daniel Weisz, Andrew Pontzen +12
We use high resolution HydroN-Body cosmological simulations to compare the assembly and evolution of a small field dwarf (stellar mass ~ 10 M, total mass 10$^{10}…
A dynamical model of the local cosmic expansion
Jorge Peñarrubia, Yin-Zhe Ma, Matthew G. Walker +1
We combine the equations of motion that govern the dynamics of galaxies in the local volume with Bayesian techniques in order to fit orbits to published distances and velocities of…
The metal-poor Knee in the Fornax Dwarf Spheroidal Galaxy
Benjamin Hendricks, Andreas Koch, Gustavo A. Lanfranchi +5
We present alpha-element abundances of Mg, Si, and Ti for a large sample of field stars in two outer fields of the Fornax dwarf spheroidal galaxy (dSph), obtained with VLT/GIRAFFE…
