摘要

We use the Swift Burst Alert Telescope (BAT) sample of hard X-ray-selected active galactic nuclei (AGN) with a median redshift of 0.03 and the 2MASS J- and K-band photometry to examine the correlation of hard X-ray emission to Eddington ratio as well as the relationship of the J- and K-band nuclear luminosity to the hard X-ray luminosity. The BAT sample is almost unbiased by the effects of obscuration and thus offers the first large unbiased sample for the examination of correlations between different wavelength bands. We find that the near-IR nuclear J- and K-band luminosity is related to the BAT (14-195 keV) luminosity over a factor of 10~3 in luminosity (L_(IR) ≈ L_(BAT)~(1.25)) and thus is unlikely to be due to dust. We also find that the Eddington ratio is proportional to the X-ray luminosity. This new result should be a strong constraint on models of the formation of the broadband continuum.
