Resolving the Complex Evolution of a Supermassive Black Hole Triplet in a Cosmological Simulation
Matias Mannerkoski, Peter H. Johansson, Antti Rantala +2
We present here a self-consistent cosmological zoom-in simulation of a triple supermassive black hole (SMBH) system forming in a complex multiple galaxy merger. The simulation is r…
MSTAR -- a fast parallelised algorithmically regularised integrator with minimum spanning tree coordinates
Antti Rantala, Pauli Pihajoki, Matias Mannerkoski +2
We present the novel algorithmically regularised integration method MSTAR for high accuracy () integrations of N-body systems using minimum spanning tree c…
Gravitational Waves from the Inspiral of Supermassive Black Holes in Galactic-scale Simulations
Matias Mannerkoski, Peter H. Johansson, Pauli Pihajoki +2
We study the orbital evolution and gravitational wave (GW) emission of supermassive black hole (SMBH) binaries formed in gas-free mergers of massive early-type galaxies using the h…
Barycentric interpolation on Riemannian and semi-Riemannian spaces
Pauli Pihajoki, Matias Mannerkoski, Peter H. Johansson
Interpolation of data represented in curvilinear coordinates and possibly having some non-trivial, typically Riemannian or semi-Riemannian geometry is an ubiquitous task in all of…
General purpose ray-tracing and polarized radiative transfer in General Relativity
Pauli Pihajoki, Matias Mannerkoski, Joonas Nättilä +1
Ray-tracing is a central tool for constructing mock observations of compact object emission and for comparing physical emission models with observations. We present Arcmancer, a pu…
