Abstract
We report the discovery of two new black widow millisecond pulsars in the globular cluster M28 with the MeerKAT telescope. J1824-2452M (M28M) is a 4.78 ms pulsar in a 4 hour orbit. J1824-2452N (M28N) is a 3.35-ms pulsar with a 4.45 hour orbit. Both pulsars are at a dispersion measure of 119.30 pc cm^-3 and appear to be black widow systems which do not show strong eclipses or orbital variation. We expect additional pulsars will be found in M28 with more sensitive observations.
