Tracing small-scale structure formation through cosmic time with strong gravitational lensing: A case for a next-generation sub-millimetre/millimetre interferometer
Hannah R. Stacey, John P. McKean, Mamta Pandey-Pommier +12
The nature of dark matter and the growth of supermassive black holes (SMBHs) remain major open questions in modern astrophysics. Both leave a key signature in an overlapping, large…
KETJU -- resolving small-scale supermassive black hole dynamics in GADGET-4
Matias Mannerkoski, Alexander Rawlings, Peter H. Johansson +5
We present the new public version of the KETJU supermassive black hole (SMBH) dynamics module, as implemented into GADGET-4. KETJU adds a small region around each SMBH where the dy…
BIFROST: simulating compact subsystems in star clusters using a hierarchical fourth-order forward symplectic integrator code
Antti Rantala, Thorsten Naab, Francesco Paolo Rizzuto +3
We present BIFROST, an extended version of the GPU-accelerated hierarchical fourth-order forward symplectic integrator code FROST. BIFROST (BInaries in FROST) can efficiently evolv…
FROST: a momentum-conserving CUDA implementation of a hierarchical fourth-order forward symplectic integrator
Antti Rantala, Thorsten Naab, Volker Springel
We present a novel hierarchical formulation of the fourth-order forward symplectic integrator and its numerical implementation in the GPU-accelerated direct-summation N-body code F…
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…
