A Search for X-ray Counterparts of Radio Pulsars

Understand

We describe a systematic search for X-ray counterparts of radio pulsars.

• The search was accomplished by cross-correlating the radio timing positions of all radio pulsars from the ATNF pulsar database (version 1.54) with archival XMM-Newton and Chandra observations publicly released by July 1st 2016.
• In total, 178 of the archival XMM-Newton observations and 213 of the archival Chandra datasets where found to have a radio pulsar serendipitously in the field of view.
• From the 288 radio pulsars covered by these datasets we identified 20 previously undetected X-ray counterparts.
