Can one-zone hadronuclear model explain the hard-TeV spectrum of BL Lac objects?
Wei-Jian Li, Rui Xue, Guang-Bo Long +4
Context. The intrinsic TeV emission of some BL Lacs are characterized by a hard spectrum (the hard-TeV spectrum) after correcting for the extragalactic background light. The hard-T…
The Origin of The Soft X-Ray Excess in the Seyfert 1.5 Galaxy ESO 362-G18
Xiao-Gu Zhong, Jian-Cheng Wang
We review the Seyfert 1.5 Galaxy ESO 362-G18 for exploring the origin of the soft X-ray excess. The Warm Corona and Relativistic Reflection models are two main scenarios to interpr…
Transient phenomena from gas-erupting neutron stars
Huiquan Li, Jiancheng Wang
Starquakes probably occur in rapidly spinning or ultra high field neutron stars. In this article, we argue that highly compressed gas containing electron-positron pairs could evapo…
A New Fast Monte Carlo Code for Solving Radiative Transfer Equations based on Neumann Solution
Xiao-lin Yang, Jian-cheng Wang, Chu-yuan Yang
In this paper, we proposed a new Monte Carlo radiative transport (MCRT) scheme, which is based completely on the Neumann series solution of Fredholm integral equation. This scheme…
A -ray Quasi-Periodic modulation in the Blazar PKS 0301243?
Peng-Fei Zhang, Da-Hai Yan, Jia-Neng Zhou +3
We report a nominally high-confidence -ray quasi-periodic modulation in the blazar PKS 0301243. For this target, we analyze its \emph{Fermi}-LAT Pass 8 data covering from 200…
ynogkm: A New Public Code For Calculating time-like Geodesics In The Kerr-Newmann Spacetime
Xiao-lin Yang, Jian-cheng Wang
In this paper we present a new public code, named , for the fast calculation of time-like geodesics in the Kerr-Newmann (K-N) spacetime, which is a direct extension of $yno…
Dependence of low redshift Type Ia Supernovae luminosities on host galaxies
Wen-Ke Liang, Jian-Cheng Wang
We study the relation of Type Ia Supernovae (SNe Ia) with host galaxies from a large low redshift sample. By examining the Hubble residuals of the entire sample from the best-fit c…
On the external photon fields in Fermi bright blazars
Xiao-Yan Gao, Jian-Cheng Wang, Ming Zhou
The external Compton (EC) model is used to study the high energy emission of some blazars, in which the external photon field is considered to dominate inverse Compton radiation. W…
Constraining spins of supermassive black holes from TeV variability. II. fully general relativistic calculations
Yan-Rong Li, Ye-Fei Yuan, Jian-Min Wang +2
The fast variability of energetic TeV photons from the center of M87 has been detected, offering a new clue to estimate spins of supermassive black holes (SMBHs). We extend the stu…
Spins of the supermassive black hole in M87: new constraints from TeV observations
Jian-Min Wang, Yan-Rong Li, Jain-Cheng Li +1
The rapid TeV ray variability detected in the well-known nearby radio galaxy M87 implies an extremely compact emission region (5-10 Schwarzschild radii) near the horizon of the…
