Wide-field Hard X-ray Survey with the Astronomical Roentgen Telescope X-ray Concentrator

The Astronomical Roentgen Telescope X-ray Concentrator (ART-XC) instrument onboard the Spectrum Röntgen Gamma (SRG) mission will survey the entire sky in the hard energy band, 5-30 keV, beginning approximatly 100 days after the scheduled March 2019 launch. The observations of the ecliptic pole regions will reach exceptional depth thanks to the survey design of overlapping exposure in these regions. In anticipation of the ART-XC survey in the North Ecliptic Pole (NEP) region, we explore publicly available multiwavelength catalogs in the NEP region and investigate AGN candidates that might exhibit hard X-ray signals that will be detected by ART-XC. To capitalize on the ART-XCcoverage in the NEP region, we also investigate ART-XC cadence and sensitivity limits for a selected few luminous X-ray sources. We also describe data analysis and simulation tools being made available to the public.
