Neutrons Star
Neutron stars are extremely dense, compact, and magnetized objects. Tiny on an astrophysical scale, with a diameter of just 25 km, they exhibit a wide range of phenomena produced by their extreme magnetospheres. A rapidly rotating neutron star...
SageManifolds
The SageManifolds project (https://sagemanifolds.obspm.fr), primarily developed at LUX, extends the SageMath software to include differential geometry and tensor calculus. This provides highly useful tools for general relativity calculations...
Modelisation of Relativistic Jets
Relativistic jets are powerful, narrow streams of particles and radiation emitted at speeds close to the speed of light, often observed around supermassive black holes in the active nuclei of galaxies.
They provide critical insights into...
Galaxy evolution in the near and far Universe
Galaxies, the building blocks of the Universe, are formed by the dissipational infall of gas into the center of dark matter haloes. They are literally where gas becomes stars. Several processes drive their evolution: gas accretion, radiative...
Computational Plasma Physics
Supernova explosions, ultra-relativistic outflows triggered by the merger of compact objects, and violent manifestations of neutron star magnetospheres are prototypical examples of matter under extreme and poorly understood conditions. Advances in...
Inhomogeneous Cosmology
The standard cosmological model, commonly used to describe the geometry and dynamics of the Universe, is based on the assumption of homogeneity in the large-scale distribution of matter. However, observations of the surrounding Universe reveal...
Characterization and Understanding of Molecular Diversity
The physico-chemical conditions of astrophysical environments can be deduced from the observation of light emitted by these regions. The analysis of observed spectral lines provides information about the nature and abundance of molecular species...
Kadath
Kadath is a numerical library implementing the use of spectral methods to solve partial differential equations arising in general relativity and theoretical physics. Spectral methods enable remarkable accuracies to be achieved with only moderate...
