PINT: A Modern Software Package for Pulsar Timing
Jing Luo, Scott Ransom, Paul Demorest +13
Over the past few decades, the measurement precision of some pulsar-timing experiments has advanced from ~10 us to ~10 ns, revealing many subtle phenomena. Such high precision dema…
Extending the and statistics to generic pulsed profiles
Matteo Bachetti, Maura Pilia, Daniela Huppenkothen +3
The search for astronomical pulsed signals within noisy data, in the radio band, is usually performed through an initial Fourier analysis to find "candidate" frequencies and then r…
Algorithmic Pulsar Timing
Camryn Phillips, Scott Ransom
Pulsar timing is a process of iteratively fitting pulse arrival times to constrain the spindown, astrometric, and possibly binary parameters of a pulsar, by enforcing integer numbe…
