The activities of the team mainly concern the observation and the study of pulsars, strongly magnetized and rapidly-rotating neutron stars. We carry out radio observations of pulsars with the telescopes of the Nançay Radio Observatory. These observations allow us to study pulsars or use them as tools for studying fundamental physics. In addition to pulsars, the team also studies Fast Radio Bursts and the radio emission from planetary magnetospheres.
The team is involved in the observation of pulsars and other astrophysical phenomena in different domains of the electromagnetic spectrum, and in particular in the radio domain with the Nançay Radio Telescope (NRT), the LOFAR telescope and the NenuFAR telescope. The team also participates in the instrumental developments needed for observing pulsars. Thanks to its observational activities, the team is involved in several large international projects of the discipline.
