The X-ray coronae in NuSTAR bright active galactic nuclei
Jia-Lai Kang, Jun-Xian Wang
We present systematic and uniform analysis of NuSTAR data with 10-78 keV S/N > 50, of a sample of 60 SWIFT BAT selected AGNs, 10 of which are radio-loud. We measure their high ener…
Distinct High Energy Cutoff Variation Patterns in Two Seyfert Galaxies
Jia-Lai Kang, Jun-Xian Wang, Wen-Yong Kang
Investigating how the cutoff energy varies with X-ray flux and photon index in individual AGNs opens a new window to probe the yet unclear coronal physics. So far…
NuSTAR hard X-ray spectra of radio galaxies
Jia-lai Kang, Jun-xian Wang, Wen-yong Kang
NuSTAR observatory, with its 3 - 78 keV broadband spectral coverage, enables the detections of the high-energy cutoff in a number of active galaxies, including several individual r…
More than softer-when-brighter: the X-Ray powerlaw spectral variability in NGC 4051
Yun-Jing Wu, Jun-Xian Wang, Zhen-Yi Cai +3
The powerlaw X-ray spectra of active galactic nuclei at moderate to high accretion rates normally appear softer when they brighten, for which the underlying mechanisms are yet uncl…
Cosmological constraints on ultra-light axion fields
Jiangang Kang, Yan Gong, Gong Cheng +1
Ultra-light axions (ULAs) with mass less than 10^-20 eV have interesting behaviors that may contribute to either dark energy or dark matter at different epochs of the Universe. Its…
