They are transient phenomena with respect to the Faint Images of the Radio Sky at Twenty Centimeters (FIRST) survey and constitute the first unbiased sample of renewed radio activity. Here we present the follow-up, radio, opticalRead More →

Revealing a New Black Widow Binary 4FGL J0336.0+7502.

Kong</a> We report on a discovery of a promising candidate as a black widow millisecond pulsar binary, 4FGL J0336.0+7502, which shows many pulsar-like properties in the 4FGL-DR2 catalog. Within the 95% error region of the LAT source, we identified an optical counterpart with a clear periodicity at P(orb) = 3.718178(9) hours using the Bohyunsan 1.8-m Telescope, Lulin One-meter Telescope, Canada-France-Hawaii Telescope, and Gemini-North. At the optical position, an X-ray source was marginally detected in the Swift/XRT archival data,Read More →
