The Origin of r-process Enhanced Metal-Poor Halo Stars In Now-Destroyed Ultra-Faint Dwarf Galaxies
Kaley Brauer, Alexander P. Ji, Anna Frebel +3
The highly r-process enhanced (r-II) metal-poor halo stars we observe today could play a key role in understanding early ultra-faint dwarf galaxies, the smallest building blocks of…
CDM Predictions for the Satellite Population of M33
Ekta Patel, Jeffrey L. Carlin, Erik J. Tollerud +2
Triangulum (M33) is the most massive satellite galaxy of Andromeda (M31), with a stellar mass of about . Based on abundance matching techniques, M33's tota…
Selecting ultra-faint dwarf candidate progenitors in cosmological N-body simulations at high redshifts
Mohammadtaher Safarzadeh, Alexander P. Ji, Gregory A. Dooley +4
The smallest satellites of the Milky Way ceased forming stars during the epoch of reionization and thus provide archaeological access to galaxy formation at . Numerical studie…
The predicted luminous satellite populations around SMC and LMC-mass galaxies - A missing satellite problem around the LMC?
Gregory A. Dooley, Annika H. G. Peter, Jeffrey L. Carlin +3
Recent discovery of many dwarf satellite galaxies in the direction of the Small and Large Magellanic Clouds (SMC and LMC) provokes questions of their origins, and what they can rev…
Tracing the first stars and galaxies of the Milky Way
Brendan F. Griffen, Gregory A. Dooley, Alexander P. Ji +3
We use 30 high-resolution dark matter halos of the simulation suite to probe the first stars and galaxies of Milky Way-mass systems. We quantify the environment of th…
An observer's guide to the (Local Group) dwarf galaxies: predictions for their own dwarf satellite populations
Gregory A. Dooley, Annika H. G. Peter, Tianyi Yang +3
A recent surge in the discovery of new ultrafaint dwarf satellites of the Milky Way has inspired the idea of searching for faint satellites, $10^3\, \mathrm{M_{\odot}} < M_* < 10^6…
