Abstract We present a catalog of hard X-ray sources detected in the first 105 months of observations with the Burst Alert Telescope (BAT) coded-mask imager on board the Swift observatory. The 105-month Swift -BAT survey is a uniform hard X-ray all-sky survey with a sensitivity of over 90% of the sky and over 50% of the sky in the 14–195 keV band. The Swift -BAT 105-month catalog provides 1632 (422 new detections) hard X-ray sources in the 14–195 keV band above the significance level. Adding to the previously known hard X-ray sources, 34% (144/422) of the new detections are identified as Seyfert active galactic nuclei (AGNs) in nearby galaxies ( ). The majority of the remaining identified sources are X-ray binaries (7%, 31) and blazars/BL Lac objects (10%, 43). As part of this new edition of the Swift -BAT catalog, we release eight-channel spectra and monthly sampled light curves for each object in the online journal and at the Swift -BAT 105-month website.
