Neural and phenotypic representation under the free-energy principle
Maxwell J. D. Ramstead, Casper Hesp, Alec Tschantz +3
The aim of this paper is to leverage the free-energy principle and its corollary process theory, active inference, to develop a generic, generalizable model of the representational…
Sophisticated Inference
Karl Friston, Lancelot Da Costa, Danijar Hafner +2
Active inference offers a first principle account of sentient behaviour, from which special and important cases can be derived, e.g., reinforcement learning, active learning, Bayes…
Observational signatures of disk and jet misalignment in images of accreting black holes
Koushik Chatterjee, Ziri Younsi, Matthew Liska +7
Black hole accretion is one of nature's most efficient energy extraction processes. When gas falls in, a significant fraction of its gravitational binding energy is either converte…
Disc Tearing and Bardeen-Petterson Alignment in GRMHD Simulations of Highly Tilted Thin Accretion Discs
M. Liska, C. Hesp, A. Tchekhovskoy +4
Luminous active galactic nuclei (AGN) and X-Ray binaries (XRBs) often contain geometrically thin, radiatively cooled accretion discs. According to theory, these are -- in many case…
On the feasibility of constraining the triaxiality of the Galactic dark halo with orbital resonances using nearby stars
Casper Hesp, Amina Helmi
It has recently been proposed that if the Galactic dark matter halo were triaxial it would induce lumpiness in the velocity distribution of halo stars in the Solar Neighbourhood th…
Formation of Precessing Jets by Tilted Black-hole Discs in 3D General Relativistic MHD Simulations
Matthew Liska, Casper Hesp, Alexander Tchekhovskoy +3
Gas falling into a black hole (BH) from large distances is unaware of BH spin direction, and misalignment between the accretion disc and BH spin is expected to be common. However,…
