Cross-calibration of NuSTAR: A Multi-observatory Snapshot of Blazar 3C273
Abstract
The Nuclear Spectroscopic Telescope Array (NuSTAR) is the first space-based observatory capable of focusing X-rays in the hard X-ray band between 3 and 79 keV. Following a successful launch in June 2012, NuSTAR performed a series of calibration observations, including an observation of the blazar 3C273. In this poster we present results of simultaneous observations of 3C273 by NuSTAR, XMM-Newton, Chandra, Suzaku, Swift and INTEGRAL taken primarily for cross-calibration and demonstrate the unique capability of NuSTAR to extend high sensitivity observations above 10 keV. We further complement this rich X-ray data set with nearly simultaneous multi-wavelength data spanning the radio, infrared, optical and gamma-ray bands in order to constrain the low-state spectral energy distribution of 3C273. We discuss both early science from 3C273 as well as the NuSTAR cross-calibration targets and plans.
