Laboratory for Studies of Radiation and Matter in Astrophysics and Atmosphere

LERMA is a research entity operated by CNRS and Observatoire de Paris, Université Pierre et Marie Curie, École normale supérieure, and Université de Cergy-Pontoise. The laboratory is organized in four Research Poles:

• Galaxies and Cosmology: studies of the early universe, inflation, cosmic microwave background; epoch of reionization; galaxy clusters; dynamics of galaxies, dark matter; galaxy formation and evolution; black holes, AGN, star formation and feedback in local and high-redshift galaxies.

• Dynamics of the Interstellar Medium and Stellar Plasmas: observational characterization of the ISM cycle; star and planet formation; ISM modeling, from diffuse gas to stars and disks, chemical diagnostics of the ISM dynamics; modeling the transport mechanisms in circumstellar plasmas; laboratory plasma experiments.

• Molecules in the Universe: studies of gas-phase collisional and reactive processes; VUV spectroscopy and photophysics, exobiology; gas-solid interactions and heterogeneous catalysis, laboratory astrophysics.

• Instrumentation and Remote Sensing: development of THz heterodyne instrumentation for large instrumental projects, Herschel/HIFI and JUICE/SWI; research and development activities: HEB and SIS mixers, Schottky diodes for applications in tunable local oscillators; Earth and planetary remote sensing, instrument software development.
