SYSTEMATIC SEARCH FOR X-RAY COUNTERPARTS OF FERMI-LAT 3FGL UNASSOCIATED SOURCES USING SWIFT OBSERVATIONS: NEW BLAZARS, PULSARS, AND MORE

SYSTEMATIC SEARCH FOR X-RAY COUNTERPARTS OF FERMI-LAT UNASSOCIATED SOURCES USING SWIFT: NEW BLAZARS PULSARS AND MOREWE PROPOSE TO USE SWIFT TO SEARCH FOR X-RAY AND UV/OPTICAL COUNTERPARTS OF UNASSOCIATED 3FGL FERMI-LAT SOURCES. PRIOR PROGRAMS LED TO SWIFT OBSERVATIONS OF 261 AND 199 FERMI UNASSOCIATED SOURCES FROM THE 1FGL AND 2FGL CATALOGS RESPECTIVELY AS WELL AS INITIAL 3FGL OBSERVATIONS. POSSIBLE X-RAY COUNTERPARTS ARE FOUND IN ~1/3 OF THESE. THESE NEW DATA WILL DETERMINE THE PROPERTIES (WITH ~5 ARCSEC POSITIONS) OF ALL DETECTED X-RAY SOURCES IN THE LAT UNIDENTIFIED 3FGL REGIONS CONTRIBUTING TO IDENTIFICATION CLASSIFICATION AND FOLLOW-UP. THIS PROPOSAL SUPPORTS THE LARGE ANALYSIS AND INTERPRETATION TASK WHICH WILL REQUIRE ADDITIONAL DATA REDUCTION SOFTWARE. THE SWIFT PI AND EXEC COMMITTEE COMMIT TO THE SWIFT OBSERVING TIME. REDUCED DATA WILL BE MADE PUBLICLY AVAILABLE TO EVERYONE.
