An Image-based Search for Pulsar Candidates in the MeerKAT Bulge Survey

The Astrophysical Journal
We report on the results of an image-based search for pulsar candidates toward the Galactic bulge. We used mosaic images from the MeerKAT radio telescope that were taken as part of a 173 deg ^2 survey of the bulge and Galactic center of our Galaxy at L ...
