Extragalactic HI survey with FAST : First look of the pilot survey results

Jiangang Kang, Ming Zhu, Mei Ai +2

As first data release of a pilot extragalactic HI survey with Five-hundred-meter Aperture Spherical radio Telescope (FAST),we extracted 544 extragalaxies from three-dimensional(3D)…

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…

Reconstructing a non-linear interaction in the dark sector with cosmological observations

Jiangang Kang

In this work we model two non-linear directly interacting scenarios in dark sector of the universe with the dimensionless parameter and , which dominate the energy exchange…

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…
