Improving on numerical simulations of nonlinear CMB anisotropies

Fullana i Alfonso, Màrius Josep; Arnau i Córdoba, Josep Vicent; Thacker, Robert John, 1970-; Couchman, Hugh M. P.; Sáez Milán, Diego P. (IOP Publishing, 2015)

An Adaptative-Particle-Particle-Particle-Mesh code (HYDRA) plus a ray-tracing procedure was used in [1] to perform an exhaustive analysis of the weak lensing anisotropy. Other nonlinear Cosmic Microwave Background anisotropies, ...
Radial stellar pulsation and three-dimensional convection. II. Two-dimensional convection in full amplitude radial pulsation

Deupree, Robert G. (Robert Gaston), 1946-; Geroux, Chris M. (American Astronomical SocietyIOP Science, 2013-07-10)

We have developed a three-dimensional radiation hydrodynamics code to simulate the interaction of convection and radial pulsation in classical variable stars. One key goal is the ability to carry these simulations to full ...
