Experiments and Modeling in Astroparticles and Cosmology
Coordinator: Alexandre MARCOWITH
The Astroparticle Modeling and Experiment (EMA) team studies astrophysical sources emitting non-thermal high-energy radiation produced by relativistic particles or cosmic rays.
The team specializes on the one hand in the study of galactic sources (supernova remnants, pulsar nebulae, massive star clusters), and on the other hand in the study of transient sources (gamma ray bursts, supernovae).
EMA team is involved in several present, FERMI, HESS and future experiments CTA, SVOM. The EMA team is also involved in the LSST project.
The team has developed a specialization ranging from instrumentation (LIDAR), data analysis (FERMI, HESS), modeling of physical processes producing high energy emission and ultimately more theoretical works dealing with acceleration and transport of cosmic rays, in particular by means of numerical simulations (using magnetohydrodynamic codes such as RAMSES, and AMR-VAC coupled to kinetic modules) and analytical calculations. More recently the team is studying the production of energetic particles of moderately relativistic energies in the environment of young stars.
