  bibo_abstract:
  - We present an analysis of NuSTAR X-ray observations of three active galactic nuclei
    (AGN) that were identified as candidate subparsec binary supermassive black hole
    (SMBH) systems in the Catalina Real-Time Transient Survey based on apparent periodicity
    in their optical light curves. Simulations predict that close-separation accreting
    SMBH binaries will have different X-ray spectra than single accreting SMBHs. We
    previously observed these AGN with Chandra and found no differences between their
    low-energy X-ray properties and the larger AGN population. However, some models
    predict differences to be more prominent at energies higher than probed by Chandra.
    We find that even at the higher energies probed by NuSTAR, the spectra of these
    AGN are indistinguishable from the larger AGN population. This could rule out
    models predicting large differences in the X-ray spectra in the NuSTAR bands.
    Alternatively, it might mean that these three AGN are not binary SMBHs.@eng
