The Thousand Pulsar Array began as one of the major science themes of MeerTime, the MeerKAT Large Survey Project devoted to pulsar timing and pulsar astrophysics. MeerTime as a MeerKAT project has now concluded. The Thousand Pulsar Array continues independently as a MeerKAT eXtremely Large Project, carrying forward the legacy of MeerTime while defining its own scientific direction, observing strategy, data releases, and community role.
The Thousand Pulsar Array is MeerTime’s large-scale programme to observe and characterise more than a thousand radio pulsars with the MeerKAT telescope. By combining MeerKAT’s sensitivity, wide bandwidth, and tied-array observing capability, TPA is building a homogeneous legacy data set for pulsar astrophysics. The programme targets high-fidelity pulse profiles, multi-epoch timing, and single-pulse observations across a large pulsar population. Its science spans a large range of topics, including pulsar emission physics, magnetospheric structure, neutron-star interiors, glitches, pulse-profile evolution, scintillation, interstellar-medium studies, and the Galactic magnetic field.
TPA data products include folded profiles, timing measurements, dispersion and rotation-measure time series, flux-density spectra, and single-pulse data products. Public releases accompany major science papers and are intended to support broad community use.
