Parkes observations for project P1054 semester 2021APRS_11

Brief description

With this proposal we ask time for a timing follow-up campaign of the first 5 mllisecond pulsars discovered in the TRAPUM (TRAnsients and PUlsars with Meerkat) survey. The sources have been detected in targeted observations of Fermi unidentified point sources. At least two of the new pulsars belong to binary systems and an initial orbital period of 8.5 hrs has already been estimated for the brightest source. Timing observations have an essential role in exploiting the full potential of any pulsar discovery, allowing the precise measurement of rotational, astrometric and orbital parameters which, in turn, give us powerful tools to improve our understanding of the physics in extreme environments as well as of the population of neutron stars as a whole. The UWL receiver of the Parkes telescope is a sensitive, versatile instrument that will allow us to successfully time these new sources, in the bright-end of TRAPUM discoveries. The UWL has also the unique advantage of allowing detailed studies of the eclipses of the so-called 'spider' pulsars, the vast majority of which have an associated Fermi counterpart.
