A survey for redback candidates with MeerKAT

Redbacks are binary star systems with a millisecond pulsar and a low-mass irradiated companion. These systems exhibit properties that can be used to study binary evolution, pulsar winds, and make neutron star mass measurements. Throughout the years, many projects have monitored Fermi-LAT gamma-ray unidentified sources across the electromagnetic spectrum. As a result, they have identified some high-confidence redback candidates using optical and X-ray light curves and which currently have no evidence of radio pulsars. Attempting to find radio pulsations from the neutron stars in these systems, we have conducted a deep survey of six redback candidates with MeerKAT at L-band and UHF as part of the Fermi working group of the MeeKAT LSP project called TRAPUM. We will present three new millisecond pulsars that we have discovered. Two of them have extraordinary eclipses. Lastly, we will also present the results of our radio and gamma-ray timing campaigns, which provide orbital parameters for pulsar-mass measurements.
