Toward data-driven many-body simulations of biomolecules in solution: N-methyl acetamide as a proxy for the protein backbone [PDF]
, 2023 The development of molecular models with quantum-mechanical accuracy for predictive simulations of biomolecular systems has been a long standing goal in the field of computational biophysics and biochemistry.

Self-consistent Spin, Tidal, and Dynamical Equations of Motion in the REBOUNDx Framework
The Astrophysical Journal, 2023 We introduce self-consistent spin, tidal, and dynamical equations of motion into REBOUNDx , a library of additional effects for the popular N -body integrator REBOUND .

N-Body Simulations of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1987 N-body simulations are a useful tool for constructing equilibrium models of elliptical galaxies and for the exploration of their kinematical properties, in particular the tumbling rate of the figure about some axis and the internal streaming. As yet little is known about these, except that there is a large variety of possible equilibrium models.

Secondary evolution of galaxies investigated by N-body simulations [PDF]
, 2008 In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

Are long-term N-body simulations reliable? [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT N-body integrations are used to model a wide range of astrophysical dynamics, but they suffer from errors which make their orbits diverge exponentially in time from the correct orbits. Over long time-scales, their reliability needs to be established. We address this reliability by running a three-body planetary system over about

Confirming Resonance in Three Transiting Systems
The Astronomical Journal, 2023 Although resonant planets have orbital periods near commensurability, resonance is also dictated by other factors, such as the planets’ eccentricities and masses, and therefore must be confirmed through a study of the system’s dynamics.

N-body Simulations of Galaxy Formation [PDF]
Symposium - International Astronomical Union, 1988 Modern N-body techniques allow the study of galaxy formation in the wider context of the formation of large-scale structure in the Universe. The results of such a study within the cold dark matter cosmogony are described. Dark galactic halos form at relatively recent epochs.

Dual Hierarchy for Gravitational n-body
, 2023 The n-body problem is the simulation of pair-wise interactions between n objects. This problem appears in many forms, with the classic example being the modeling of gravitational forces between point masses, necessary for cosmological simulations.

On Parallel and Distributed N-Body Simulations
MathematicsThe N-body problem is a classic problem involving a system of N discrete bodies mutually interacting in a dynamical system. At any moment in time there are N(N−1)/2 such interactions occurring.

The generation of vorticity in cosmological N-body simulations [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 Clustering of a perfect fluid does not lead to the generation of vorticity. It is the collisionless nature of dark matter, inducing velocity dispersion and shell crossing, which is at the origin of cosmological vorticity generation. In this paper we investigate the generation of vorticity during the formation of cosmological large scale structure using
