NICER observation list: Target ID 463801

Abstract

A time-domain variability analysis of 117 blazars in the Swift-BAT 105-month catalog reveals that a significant portion (~30%) exhibit very low fractional variability (<20%) on a monthly timescale, which is deeply at odds with previous studies that show that blazars are highly variable in the X-rays on a wide range of timescales. However, the BAT data are not sensitive to changes on shorter timescales or lower amplitude variability. We propose NICER observations of four 'quiescent' BAT blazars whose variability is not detected by the BAT to determine if a subset of this population show variability at lower amplitudes and shorter timescales. The higher sensitivity per unit time of NICER and its scheduling flexibility make it an ideal instrument with which to carry out this investigation.
