Decreasing Computing Time with Symplectic Correctors in Adaptive Timestepping Routines
Nathan A. Kaib, Thomas Quinn, Ramon Brasser
It has previously been shown that varying the numerical timestep during a symplectic orbital integration leads to a random walk in energy and angular momentum, destroying the phase…
Origin and Dynamics of the Mutually Inclined Orbits of Upsilon Andromedae c and d
Rory Barnes, Richard Greenberg, Thomas R. Quinn +2
We evaluate the orbital evolution and several plausible origins scenarios for the mutually inclined orbits of Upsilon Andromedae c and d. These two planets have orbital elements th…
The Genesis of the Milky Way's Thick Disk via Stellar Migration
Sarah R. Loebman, Rok Roskar, Victor P. Debattista +3
The separation of the Milky Way disk into a thin and thick component is supported by differences in the spatial, kinematic and metallicity distributions of their stars. These diffe…
Wandering Black Holes in Bright Disk Galaxy Halos
Jillian Bellovary, Fabio Governato, Tom Quinn +3
We perform SPH+N-body cosmological simulations of massive disk galaxies, including a formalism for black hole seed formation and growth, and find that satellite galaxies containing…
Misaligned Angular Momentum in Hydrodynamic Cosmological Simulations: Warps, Outer Discs, and Thick Discs
Rok Roškar, Victor P. Debattista, Alyson M. Brooks +5
We present a detailed analysis of a disc galaxy forming in a high-resolution fully cosmological simulation to investigate the nature of the outer regions of discs and their relevan…
Star Formation and Feedback in Smoothed Particle Hydrodynamic Simulations II: Resolution Effects
Charlotte Christensen, Thomas Quinn, Gregory Stinson +2
We examine the effect of mass and force resolution on a specific star formation (SF) recipe using a set of N-body/Smooth Particle Hydrodynamic simulations of isolated galaxies. Our…
