Upper Limits on Periodic, Pulsed Radio Emission from the X-Ray Point Source in Cassiopeia A
The Chandra X-Ray Observatory recently discovered an X-ray point source near the center of Cassiopeia A, the youngest known Galactic supernova remnant. We have conducted a sensitive search for radio pulsations from this source with the Very Large Array, taking advantage of the high angular resolution of the array to …
