Linear instability of viscous parallel shear flows: revisiting the perturbation no-slip condition
John O. Dabiri, Anthony Leonard
Linear stability analysis currently fails to predict turbulence transition in canonical viscous flows. We show that two alternative models of the boundary condition for incipient p…
Vortex Ring Reconnections
Philippe Chatelain, Demosthenes Kivotides, Anthony Leonard
We investigate numerically the Navier-Stokes dynamics of reconnecting vortex rings at small number. We find that reconnections are dissipative due to the smoothing of vorticit…
Measuring the equation of state of the intergalactic medium
Joop Schaye, Tom Theuns, Anthony Leonard +1
(Abridged) Numerical simulations indicate that the intergalactic medium (IGM) responsible for the low column density Lyman-alpha forest follows a well defined temperature-density r…
Measuring the temperature of the intergalactic medium
Joop Schaye, Tom Theuns, Anthony Leonard +1
Numerical simulations indicate that the smooth, photoionized intergalactic medium (IGM) responsible for the low column density Lyman-alpha forest follows a well defined temperature…
Dependencies of QSO Lyman-alpha absorption line statistics on cosmological parameters
Tom Theuns, Anthony Leonard, Joop Schaye +1
We have performed high-resolution hydrodynamic simulations of the Lyman-alpha forest in a variety of popular cold dark matter dominated cosmologies, including a low density and a v…
P3M-SPH simulations of the Lyman-alpha Forest
Tom Theuns, Anthony Leonard, George Efstathiou +2
(Abridged) We investigate the importance of several numerical artifacts such as lack of resolution on spectral properties of the Lyman alpha forest as computed from cosmological hy…
