Dynamical Evolution of Quasi-Hierarchical Triples
Yonadav Barry Ginat, Jakob Stegmann, Johan Samsing
We study the gravitational dynamics of quasi-hierarchical triple systems, where the outer orbital period is significantly longer than the inner one, but the outer orbit is extremel…
Cosmic-ray transport in inhomogeneous media
Robert J. Ewart, Patrick Reichherzer, Shuzhe Ren +6
A theory of cosmic-ray transport in multi-phase diffusive media is developed, with the specific application to cases in which the cosmic-ray diffusion coefficient has large spatial…
Angular-momentum pairs in spherical systems: applications to the Galactic centre
Taras Panamarev, Yonadav Barry Ginat, Bence Kocsis
Consider a system of point masses in a spherical potential. In such systems objects execute planar orbits covering two-dimensional rings or annuli, represented by the angular-momen…
Constraining Axion Dark Matter with Galactic-Centre Resonant Dynamics
Yonadav Barry Ginat, Bence Kocsis
We study the influence of fuzzy-dark-matter cores on the orbits of stars at the Galactic centre. This dark matter candidate condenses into dense, solitonic cores, and, if a super-m…
Gravitational Turbulence: the Small-Scale Limit of the Cold-Dark-Matter Power Spectrum
Yonadav Barry Ginat, Michael L. Nastac, Robert J. Ewart +3
The matter power spectrum, , is one of the fundamental quantities in the study of large-scale structure in cosmology. Here, we study its small-scale asymptotic limit, and sho…
Detection prospects for the GW background of Galactic (sub)solar mass primordial black holes
Frans van Die, Ivan Rapoport, Yonadav Barry Ginat +1
In multi-component dark matter models, a fraction of the dark matter could be in the form of primordial black holes (PBHs) with (sub)solar masses. Some would have fo…
