Abstract
The Event Horizon Telescope (EHT) is effectively an Earth-sized, interferometric mm-band telescope array with 20 muas spatial resolution that is conducting ground-breaking observations of supermassive black hole (SMBH) systems. The mm emission size resolved by EHT in SMBH are consistent with those inferred from X-ray and gamma-ray variability studies. We propose joint NICER/NuSTAR observations of two blazars during the Spring 2020 EHT campaign: 3C 273 and 3C 279. The former is an EHT target, and the latter is a calibrator for M87 observations. NICER will provide large effective area, low background, and rapid timing capabilities in the soft X-ray, and the joint spectra will span 0.1-70 keV. These blazars have shown both long term and short term flaring variability.
