We present the Suzaku broad band observations of two AGNs detected by the Swift/BAT hard X-ray (>15 keV) survey that did not have previous X-ray data, Swift J0601.9–8636 and Swift J0138.6–4001. The Suzaku spectra reveals in both objects a heavily absorbed power law component with a column density of NH ≃ 1023.5−24cm−2 that dominates above 10 keV, and an intense reflection component with a solid...
We report on NuSTAR, XMM-Newton and Swift observations of the gamma-ray binary 1FGL J1018.6−5856. We measure the orbital period to be 16.544 ± 0.008 days using Swift data spanning 1900 days. The orbital period is different from the 2011 gamma-ray measurement which was used in the previous X-ray study of An et al. (2013) using ∼400days of Swift data, but is consistent with a new gamma-ray soluti...
