On radial anisotropy limits in stellar systems
Jeremy A. Barber, Hongsheng Zhao
Following earlier authors, we re-examine constraints on the radial velocity anisotropy of generic stellar systems using arguments for phase space density positivity, stability, and…
Stirring N-body systems II: Necessary conditions for the dark matter attractor
Jeremy A. Barber, Hongsheng Zhao, Steen H. Hansen
We study the evolution of the phase-space of collisionless N-body systems under repeated stirrings or perturbations, which has been shown to lead to a convergence towards a limited…
Stirring N-body systems: Universality of end states
Jeremy A. Barber, Hongsheng Zhao, Xufen Wu +1
We study the evolution of the phase-space of collisionless N-body systems under repeated stirrings or perturbations. We find convergence towards a limited solution group, in accord…
The reinstatement of funding to the Overwhelmingly Large Telescope Project
Jeremy A. Barber
While space-based telescopes have had a part to play ultimately I feel that it is telescopes like myself that have contributed the most to pushing the boundaries of our knowledge.…
