PSR J0437-4715: The Argentine Institute of Radioastronomy 2019-2020 Observational Campaign

Understand

The Argentine Institute of Radio astronomy (IAR) is equipped with two single-dish 30-m radio antennas capable of performing daily observations of pulsars and radio transients in the southern hemisphere at 1.4 GHz.

• We aim to contribute to pulsar timing studies related to short time-scale interstellar scintillation and searches for sources of continuous gravitational waves.
• We performed high-cadence (almost daily) and long-duration observations of the bright millisecond pulsar J0437$-$4715 for over a year, gathering more than 700 hours of good-quality data with timing precision better than 1~$\mu$s.
• We characterize the white and red timing noise in IAR's observations of J0437$-$4715.
