The NuSTAR AGN Physics Program
Abstract
The launch of the Nuclear Spectroscopic Telescope Array (NuSTAR) in June 2012 has opened a new window onto the high-energy universe. The study of active galactic nuclei (AGN) and the supermassive black holes (SMBHs) within them stands to benefit greatly from this observatory. NuSTAR's unique combination of focusing X-ray optics, large effective area and low background over the 5-80 keV energy band allows us to unambiguously probe the nature of complex AGN environs. I will review the planned AGN Physics Program science goals for the mission with a particular focus on NuSTAR's participation in simultaneous, multi-observatory campaigns on several bright, nearby AGN. Obtaining high signal-to-noise spectra across a broad bandpass is crucial for NuSTAR's cross-calibration with other instruments. Such comprehensive spectra will also allow the mission to meet one of its most critical science goals: to conclusively isolate and further understand the complex processes at work in AGN, e.g., the nature of the X-ray continuum, absorption and reflection seen in the innermost regions of these sources. Precise, accurate measurements of SMBH spins and coronal temperatures, in particular, are two key objectives of the AGN Physics Program.
