First NenuFAR pulsar catalog

We present the first low-frequency pulsar census of the northern sky with the NenuFAR radio telescope (10-85 MHz), performed during its commissioning and early science phase in 2019-2021. Our programme was conceived as the first stepping stone of a future pulsar key science project, aimed at preparing for targeted studies on pulsars of peculiar interest (mode switching, drifting subpulses, and polarised emission), exploring pulsar spectra and pulse-shape evolution below the expected turn-over, and investigating dispersion and scattering due to the interstellar and heliospheric plasma.

We observed all known pulsars observable from the Nancay Radio Observatory in France, i.e. with a declination above -20{deg} and dispersion measures (DMs) up to 100pc/cm^-3^. At the time of the sample selection, 576 pulsars fulfilled these criteria in the ATNF pulsar catalogue. We complemented this sample with 69 additional LOTAAS/LOFAR pulsars, yielding 645 observed pulsars.
