Investigating rotation in young massive clusters by means of hydrodynamical and direct N-body simulations [PDF]

open access: yes, 2022
One of the main open questions of star formation is the process of star clusters aggregation. In my thesis I investigate the kinematical features of embedded star clusters through hydrodynamical and N-body simulations.

The complexity of N-body simulation [PDF]

open access: yes, 1993
The n-body simulation problem is stated as follows: Given initial positions and velocities of n particles that have pair-wise force interactions, simulate the movement of these particles so as to determine the positions of the particles at a future time.

Revisiting Vainshtein Screening for fast N-body simulations [PDF]

open access: yes, 2023
We revisit a method to incorporate the Vainshtein screening mechanism in N-body simulations proposed by R. Scoccimarro in~\cite{Scoccimarro:2009eu}. We further extend this method to cover a subset of Horndeski theories that evade the bound on the speed ...

Dynamical Analysis of the Maclaurin Disk with Velocity Dispersion and Its Influence on the Formation of the Bar

open access: yesThe Astrophysical Journal, 2023
We investigate the influence of Toomre’s Q parameter on the bar-forming dynamics of the Maclaurin disk using N -body simulations. According to Toomre’s criterion, the local velocity dispersion parametrized by Q ≥ 1 is required to suppress the local ...

On Distributed Gravitational N-Body Simulations

open access: yesCoRR, 2022
The 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. This scaling as N^2 leads to computational difficulties where simulations range from tens of thousands of bodies to many millions.

Collisional Growth and Fragmentation of Dust Aggregates. II. Mass Distribution of Icy Fragments

open access: yesThe Astrophysical Journal, 2023
By performing N -body simulations, we investigated the fundamental processes of collisions between dust aggregates composed of submicron-sized icy dust monomers.

Halo modelling in chameleon theories [PDF]

open access: yes, 2014
We analyse modelling techniques for the large-scale structure formed in scalar-tensor theories of constant Brans-Dicke parameter which match the concordance model background expansion history and produce a chameleon suppression of the gravitational ...
