Discovery of a 62-min long-period transient with near-orthogonal rotator geometry

Scott D. Hyman, Natasha Hurley-Walker, Dale A. Frail +3

We report the serendipitous discovery of J155543.7563102 (hereafter LPT J15555631) with a period of 62.2 min in MeerKAT and ASKAP survey data. The source emitted bright (10-3…

Discovery of Millisecond Pulsars toward the Galactic Bulge in an Image-based Survey with MeerKAT

Rahul Sengar, Akash Anumarlapudi, David L. Kaplan +3

We report on the follow-up observations of circularly polarized sources identified in the MeerKAT image-based survey of the Galactic bulge. Using the Parkes radio telescope, we obs…

A Radio Flaring, Chromospherically-Inactive K Dwarf

Dale A. Frail, Scott D. Hyman, Michele L. Silverstein +10

We report on an unusual radio source J180526-292953, initially identified as a steep spectrum, polarized point source toward the Galactic bulge and found to coincide with the nearb…

Fermi Unassociated Sources in the MeerKAT Absorption Line Survey

Morgan Himes, Preshanth Jagannathan, Dale Frail +8

Over 2000 Gamma ray sources identified by the Large Area Telescope (LAT) on NASA's Fermi Gamma-ray Space Telescope are considered unassociated, meaning that they have no known coun…

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

Dale A. Frail, Emil Polisensky, Scott D. Hyman +13

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 o…

Cannonball or Bowling Ball: A Proper Motion and Parallax for PSR J0002+6216

S. Bruzewski, F. K. Schinzel, G. B. Taylor +4

We report the results of careful astrometric measurements of the Cannonball pulsar J0002+6216 carried out over three years using the High Sensitivity Array (HSA). We significantly…
