First results from the UTMOST-NS pulsar timing programme

Abstract

The UTMOST-NS pulsar timing programme operated at the Molonglo Observatory Synthesis Telescope from 2021 April to 2023 June, observing 173 pulsars with an average cadence of 50 pulsars per day. An overview of the programme is presented, detailing the hardware, software, and observing strategy. Pulsar timing results are discussed, focusing on timing noise and glitches. It is shown that the scaling of residuals due to timing noise with pulsar parameters and observing time span is consistent with earlier studies, and that the recovered timing noise parameters remain consistent as the observing time span is increased. Second frequency derivatives are investigated, and it is shown that the uncert..
