Tidal features of classical Milky Way satellites in a CDM universe
M. -Y. Wang, Azadeh Fattahi, Andrew P. Cooper +6
We use the APOSTLE cosmological hydrodynamic simulations to examine the effects of tidal stripping on cold dark matter (CDM) sub haloes that host three of the most luminous Milky W…
Post-Newtonian dynamical modeling of supermassive black holes in galactic-scale simulations
Antti Rantala, Pauli Pihajoki, Peter H. Johansson +3
We present KETJU, a new extension of the widely-used smoothed particle hydrodynamics simulation code GADGET-3. The key feature of the code is the inclusion of algorithmically regul…
Properties of Local Group galaxies in hydrodynamical simulations of sterile neutrino dark matter cosmologies
Mark R. Lovell, Sownak Bose, Alexey Boyarsky +10
We study galaxy formation in sterile neutrino dark matter models that differ signifi- cantly from both cold and from `warm thermal relic' models. We use the EAGLE code to carry out…
The oldest and most metal poor stars in the APOSTLE Local Group simulations
Else Starkenburg, Kyle A. Oman, Julio F. Navarro +5
We examine the spatial distribution of the oldest and most metal poor stellar populations of Milky Way-sized galaxies using the APOSTLE cosmological hydrodynamical simulations of t…
Shaken and Stirred: The Milky Way's Dark Substructures
Till Sawala, Pauli Pihajoki, Peter H. Johansson +4
The predicted abundance and properties of the low-mass substructures embedded inside larger dark matter haloes differ sharply among alternative dark matter models. Too small to hos…
The cold dark matter content of Galactic dwarf spheroidals: no cores, no failures, no problem
Azadeh Fattahi, Julio F. Navarro, Till Sawala +5
We examine the dark matter content of satellite galaxies in Lambda-CDM cosmological hydrodynamical simulations of the Local Group from the APOSTLE project. We find excellent agreem…
Knowing the unknowns: uncertainties in simple estimators of galactic dynamical masses
David J. R. Campbell, Carlos S. Frenk, Adrian Jenkins +7
The observed stellar kinematics of dispersion-supported galaxies are often used to measure dynamical masses. Recently, several analytical relationships between the stellar line-of-…
The low-mass end of the baryonic Tully-Fisher relation
Laura V. Sales, Julio F. Navarro, Kyle Oman +11
The scaling of disk galaxy rotation velocity with baryonic mass (the "Baryonic Tully-Fisher" relation, BTF) has long confounded galaxy formation models. It is steeper than the M ~…
Missing dark matter in dwarf galaxies?
Kyle A. Oman, Julio F. Navarro, Laura V. Sales +5
We use cosmological hydrodynamical simulations of the APOSTLE project along with high-quality rotation curve observations to examine the fraction of baryons in ΛCDM haloes that col…
