Fundamental Physics and Relativistic Laboratory Astrophysics with Extreme Power Lasers
Fundamental Physics Relativistic Laboratory Astrophysics Extreme Power Lasers
2012/2/23
The prospects of using extreme relativistic laser-matter interactions for laboratory astrophysics are discussed. Laser-driven process simulation of matter dynamics at ultra-high energy density is prop...
Astrophysics and cosmology with galaxy clusters: the WFXT perspective
Astrophysics cosmology galaxy clusters
2011/1/13
We discuss the central role played by the X-ray study of hot baryons within galaxy clusters to reconstruct the assembly of cosmic structures and to trace the past history of star formation and accret...
Applications of the IGIMF-theory to the astrophysics of galaxies
Applications astrophysics of galaxies
2010/11/12
The functional form of the galaxy-wide stellar initial mass function is of fundamental importance for understanding galaxies. So far this stellar initial mass function has been assumed to be identical...
Numerically determined transport laws for fingering ("thermohaline") convection in astrophysics
hydrodynamics instabilities turbulence
2010/11/16
We present the first three-dimensional simulations of fingering convection performed in a parameter regime close to the one relevant for astrophysics, and reveal the existence of simple asymptotic sca...
Wild at Heart:-The Particle Astrophysics of the Galactic Centre
cosmic rays { galaxies star formation { Galaxy center { ISM
2010/11/9
We treat of the high-energy astrophysics of the inner 200 pc of the Galaxy. Our modelling of this region shows that the supernovae exploding here every few thousand years inject enough power to i) su...
Radiative cooling in numerical astrophysics: the need for adaptive mesh refinement
Computational techniques fluid dynamics Radiative recombination Radiative transfer in astrophysics
2010/11/15
Energy loss through optically thin radiative cooling plays an important part in the evolution of astrophysical gas dynamics and should therefore be considered a necessary element in any numerical simu...
Ab initio Stellar Astrophysics: Reliable Modeling of Cool White Dwarf Atmospheres
Solar and Stellar Astrophysics (astro-ph.SR) Materials Science (cond-mat.mtrl-sc)
2010/12/27
Over the last decade {\it ab initio} modeling of material properties has become widespread in diverse fields of research. It has proved to be a powerful tool for predicting various properties of matte...
Measurements of stellar and explosive nuclear astrophysics reactions

The field of computational astrophysics (CA) has seen many recent advances.The emergence of higher order Go dunov schemes for many of the systems of inter-est in CA represents a development of great i...
Predicting the future from observable sequences of events in astrophysics I. Maximum Likelihood Estimation for a fixed number of parameters
astrophysics Maximum Likelihood
2009/5/27
Using analytical and numerical methods, estimates are given of future predictions in astrophysics that can be gathered from a sequence of observed events, for example for γ-ray bursts. Some general pr...
Studies in Nuclear Astrophysics Using Radioactive Beams at the HRIBF
Nuclear Astrophysics Radioactive Beams the HRIBF
2010/10/22
The availability of radioactive beams has produced great opportunities for advances in our understanding of the nucleosynthesis occurring in stellar explosions such as novae, X-ray bursts, and superno...
