Built in the mid-1960s, the Nançay Radio Telescope (NRT), equivalent in sensitivity to a 94 m diameter dish, is the only European radio telescope with a single antenna entirely dedicated to the decimeter band (1.1-3.5 GHz). The instrument operates continuously, 24/24h, 365 days a year. It allows long-term and/or large-scale programs and offers the possibility of observing on alert (supernova explosion follow-up, radio emission associated with a gamma-ray burst or a gravitational event, new comet). The NRT has for example produced the largest number of measurements of galaxies at 21cm wavelength after the Arecibo radio telescope, and it currently provides the world community with the densest and most accurate series of millisecond pulsar timings at the European level.
Ismaël Cognard is the scientific manager of the instrument. He coordinates its operation and maintenance with technical staff at the Nançay Radio Observatory. Gilles Theureau is in charge of the Observation Service associated with the instrument, which ensures the return to the community within the National Institute of Sciences of the Universe of CNRS (INSU).
