LERMA (Laboratory for Studies of Radiation and Matter in Astrophysics and Atmospheres) is a research entity operated by CNRS and three higher education institutions : Observatoire de Paris (OP),Sorbonne Université (SU), École normale supérieure (ENS), and Université de Cergy-Pontoise (UCP). These institutions host the various LERMA research groups.

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.

These research poles are complemented by a transverse structure, dedicated to :
