Long-term project observations for project L152 semester 2026APRS_01

PSR J1757-1854 is the most relativistic galactic double neutron star system. Its eccentricity makes it an ideal playground for gravity experiments with pulsar timing. Via observations of its profile evolution, we can constraint its rate of geodetic precession. Currently, there are four possible geometric configurations that explain the time evolution of the polarisation swing. The geodetic precession and the Lense-Thirring effect will eventually manifest themselves in the post-Keplerian parameters within the next decade, allowing for two further tests of gravity. We propose a regular monitoring of this source to extend the timing baseline and contribute towards the tests of gravity. We will inspect the polarisation properties of this observation, and we will add the ToAs to a global timing campaign. These observations will be added to joint GBT and MeerKAT observations, and they will be part of a long-term, global observational program of this pulsar.
