Long-term project observations for project P1041 semester 2025APRS_04

Omega Cen is the largest globular cluster in the Milky Way. I contains at least 18 known MPSs, and there are solid hints for the presence of an even larger pulsar population. We propose a regular monthly follow-up to refine the timing solutions of the five Parkes discoveries from 2020, and to find timing solutions for the 13 MeerKAT discoveries from 2023, in combination with six MeerKAT observations between 2021 and 2023, and future MeerKAt observations. These timing solutions should enable the detection of derivatives of the spin periods of these puslars, allowing us to probe the dynamics of Omega Cen and the the presence of a possible IMBH at its centre. Timing solutions will also enable the search for X-ray and gamma-ray pulsations in the multiple sources detected in this cluster. This study will allow us to better understand the populations of this globular cluster and its formation history. We request observations until 2030, when we expect to have measurements of the second period derivative of the five brighter discoveries, and first period derivative measurements for the later discoveries. These observations will also contribute to the study of eclipsing binaries, and may include future discoveries from pending searches in MeerKAT data.
