X-Ray flare in the Nearby TeV-Detected Blazar 1ES 1727+502
Abstract
1ES 1727+502 (1Zw 187, z=0.055), a nearby TeV-detected blazar, has been targeted 166 times with X-Ray Telescope onboard Neil Gehrels Swift Observatory during 2010 April 2 - 2020 December 15 with a net exposure of 226 ks. During this period, the 0.3-10 keV count rate varied by a factor of 18, and reached the value of 4.96+/-0.06 cts/s on 2015 November 11 when the source was showing a prolonged X-ray flaring activity (observed mostly in the framework of our ToO requests with different urgencies; see http://www.swift.psu.edu/monitoring /source.php?source=QSOB1727+502 and Kapanadze B. 2015, Atel #8224, #7342).
