The 3-dimensional architecture of the Upsilon Andromedae planetary system
Russell Deitrick, Rory Barnes, Barbara McArthur +4
The Upsilon Andromedae system is the first exoplanetary system to have the relative inclination of two planets' orbital planes directly measured, and therefore offers our first win…
Adaptive Techniques for Clustered N-Body Cosmological Simulations
Harshitha Menon, Lukasz Wesolowski, Gengbin Zheng +4
ChaNGa is an N-body cosmology simulation application implemented using Charm++. In this paper, we present the parallel design of ChaNGa and address many challenges arising due to t…
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}…
Orbital Decay of Supermassive Black Hole Binaries in Clumpy Multiphase Merger Remnants
R. Roškar, L. Mayer, D. Fiacconi +3
We simulate an equal-mass merger of two Milky Way-size galaxy discs with moderate gas fractions at parsec-scale resolution including a new model for radiative cooling and heating i…
Effects of Extreme Obliquity Variations on the Habitability of Exoplanets
J. C. Armstrong, R. Barnes, S. Domagal-Goldman +3
We explore the impact of obliquity variations on planetary habitability in hypothetical systems with high mutual inclination. We show that large amplitude, high frequency obliquity…
