Ray-tracing and polarized radiative transfer in General Relativity
Pauli Pihajoki, Antti Rantala, Peter H. Johansson
We discuss the problem of polarized radiative transfer in general relativity. We present a set of equations suitable for solving the problem numerically for the case of an arbitrar…
Post-Newtonian dynamical modeling of supermassive black holes in galactic-scale simulations
Antti Rantala, Pauli Pihajoki, Peter H. Johansson +3
We present KETJU, a new extension of the widely-used smoothed particle hydrodynamics simulation code GADGET-3. The key feature of the code is the inclusion of algorithmically regul…
Shaken and Stirred: The Milky Way's Dark Substructures
Till Sawala, Pauli Pihajoki, Peter H. Johansson +4
The predicted abundance and properties of the low-mass substructures embedded inside larger dark matter haloes differ sharply among alternative dark matter models. Too small to hos…
