A New Method to Study the Origin of the EGB and the First Application on AT20G

Ming Zhou, Jiancheng Wang, Xiaoyan Gao

In this letter, we introduce a new method of image stacking to directly study the undetected but possible gamma-ray point sources. Applying the method to the Australia Telescope 20…

X-Ray Properties of Narrow-Line Seyfert 1 Galaxies with Very Small Broad-Line Widths

Y. L. Ai, W. Yuan, H. Y. Zhou +2

Narrow-line Seyfert\,1 galaxies (NLS1s) with very small broad-line widths (say, FWHM(\hb) $\la $ 1200\,\kms) represent the extreme type of Seyfert\,1 galaxies that have small black…

The effect of coronal radiation on a residual inner disk in the low/hard spectral state of black hole X-ray binary systems

B. F. Liu, C. Done, Ronald E. Taam

Thermal conduction between a cool accretion disk and a hot inner corona can result in either evaporation of the disk or condensation of the hot corona. At low mass accretion rates,…

A High-Order WENO-based Staggered Godunov-type Scheme with Constrained Transport for Force-free Electrodynamics

Cong Yu

The force-free (or low inertia) limit of magnetohydrodynamics (MHD) can be applied to many astrophysical objects, including black holes, neutron stars, and accretion disks, where t…

X-ray observational signature of a black hole accretion disc in an active galactic nucleus RXJ1633+4718

Weimin Yuan, Bifang Liu, Hongyan Zhou +1

We report the discovery of a luminous ultra-soft X-ray excess in a radio-loud narrow-line Seyfert1 galaxy, RXJ1633+4718, from archival ROSAT observations. The thermal temperature o…

Helium star evolutionary channel to super-Chandrasekhar mass type Ia supernovae

W. -M. Liu, W. -C. Chen, B. Wang +1

Recent discovery of several overluminous type Ia supernovae (SNe Ia) indicates that the explosive masses of white dwarfs may significantly exceed the canonical Chandrasekhar mass l…

Constraining Extragalactic Background Light From TeV Blazars

Jianping Yang, Jiancheng Wang

Our goal is to research the upper limits on the extragalactic background light (EBL). The upper limits on the extragalactic background light (EBL), using the Fermi and very high en…

Redshifts of distant blazar limited by Fermi and VHE -ray observations

Jianping Yang, Jiancheng Wang

Our goal is to limit the redshifts of three blazars PG 1553+113, 3C 66A and PKS 1424+240, through the investigation of their Fermi and VHE (very high energy) -ray observations.…

The Temporal and Spectral Characteristics of "Fast Rise and Exponential Decay" Gamma-Ray Burst Pulses

Z. Y. Peng, Y. Yin, X. W. Bi +4

In this paper we have analyzed the temporal and spectral behavior of 52 Fast Rise and Exponential Decay (FRED) pulses in 48 long-duration gamma-ray bursts (GRBs) observed by the CG…

A Theoretical Investigation on the Gamma-ray Burst Host Galaxies

J. Mao

Long-duration gamma-ray bursts(LGRBs) are believed to be linked with the star formation. We adopt a galactic evolution model, in which the star formation process inside the viriali…

The bulk Lorentz factors of Fermi-LAT GRBs

Xiaohong Zhao, Zhuo Li, Jinming Bai

The Lorentz factor (LF) of gamma-ray burst (GRB) ejecta may be constrained by observations of high-energy (HE) spectral attenuation. The recent Fermi-LAT observations of prompt GeV…

Gamma-Ray Burst long lasting X-ray flaring activity

M. G. Bernardini, R. Margutti, G. Chincarini +2

In this paper we shed light on late time (i.e. with peak time t_{pk} \gtrsim 1000 s) flaring activity. We address the morphology and energetic of flares in the window \sim 10^3-10^…

Jet Precession Driven by Neutrino-Cooled Disc for Gamma-Ray Bursts

Tong Liu, En-Wei Liang, Wei-Min Gu +3

A model of jet precession driven by a neutrino-cooled disc around a spinning black hole is present in order to explain the temporal structure and spectral evolution of gamma-ray bu…

The Correlated Multi-color Optical Variations of BL Lac Object S5 0716+714

Bingkai Zhang, Benzhong Dai, Li Zhang +2

S5 0716+714 is a well-studied BL Lac object in the sky. Verifying the existence of correlations among the flux variations in different bands serves as an important tool to investig…
