Turbulent pair separation due to multi scale stagnation point structure and its time asymmetry in two-dimensional turbulence
Tristan Faber, J. C. Vassilicos
The pair separation model of Goto and Vassilicos (S Goto and J C Vassilicos, 2004, New J.Phys., 6, p.65) is revisited and placed on a sound mathematical foundation. A DNS of two di…
Galactic halos and gravastars: static spherically symmetric spacetimes in modern general relativity and astrophysics
Tristan Faber
The crucial role played by pressure in general relativity is explored in the mathematically simple context of a static spherically symmetric geometry. By keeping all pressure terms…
Combining rotation curves and gravitational lensing: How to measure the equation of state of dark matter in the galactic halo
Tristan Faber, Matt Visser
We argue that combined observations of galaxy rotation curves and gravitational lensing not only allow the deduction of a galaxy's mass profile, but also yield information about th…
Gravastars must have anisotropic pressures
Celine Cattoen, Tristan Faber, Matt Visser
One of the very small number of serious alternatives to the usual concept of an astrophysical black hole is the "gravastar" model developed by Mazur and Mottola; and a related phas…
Effective refractive index tensor for weak field gravity
Petarpa Boonserm, Celine Cattoen, Tristan Faber +2
Gravitational lensing in a weak but otherwise arbitrary gravitational field can be described in terms of a 3 x 3 tensor, the "effective refractive index". If the sources generating…
