The ‘Science Using Single-Pulse Exploration with Combined Telescopes’ (SUSPECT) project is a multi-frequency multi-telescope radio pulsar observing programme running at the Nançay Radio Observatory telescopes (10–85 MHz, 110–240 MHz, and 1.1–3.5 GHz) in France and the upgraded Giant Metrewave Radio Telescope (uGMRT) in India. The Nançay Observatory telescopes used for this project include NenuFAR, the French LOFAR station FR606, and the Nançay Radio Telescope (NRT).
In this project, we study the multi-frequency radio emission of pulsars, which are rapidly rotating and highly magnetized neutron stars. In particular, we focus on understanding their wideband single-pulse emission.
Publications
10) SUSPECT Paper I Zenodo data publication
This includes the integrated pulse profile of PSR B1822-09 at 650 MHz obtained from our uGMRT observations, as well as the entire dataset (8723 files) of single pulse dynamic spectrum plots in PDF format. This amounts to about 5 GB of data, which is only a small fraction of the entire single-pulse dataset.
