Research

*Dr. Cesarsky is known for her research activities in several central areas of modern astrophysics. The first part of her career was devoted to the high-energy domain. This has involved studies of the propagation and composition of galactic cosmic rays, of matter and fields in the diffuse interstellar medium, as well as the acceleration of particles in astrophysical shocks, e.g. in connection with supernovae. *She then turned to infrared astronomy. She was the principal investigator of the camera on board the

, which flew between 1995 and 1998. As such, she has led the central programme, which studied the infrared emission from a variety of galactic and extragalactic sources and yielded new and exciting results on star formation and galactic evolution. These were consolidated through further observations with the ESO VLT, the satellites Spitzer and now Herschel.
