Locating the Production Sites of High-Energy Neutrinos in Blazar Jets
Rui Xue, Yoshiyuki Inoue, Ze-Rui Wang +2
The production sites of high-energy neutrinos in blazar jets remain poorly constrained. In this work, we investigate the physical conditions required for efficient neutrino product…
On the maximum neutrino flux of blazars in the one-zone leptohadronic model
Wei-Jian Li, Rui Xue, Ze-Rui Wang +1
The origin of extragalactic high-energy neutrinos remains a major mystery in astrophysics, with blazars as leading candidate sources. The widely adopted one-zone leptohadronic jet…
Quasi-Simultaneous Broadband Spectral Energy Distributions of a Sample of Fermi Blazars -- I. Correlation Results
Yi Zhong, Zhujian Wan, Rui Xue +3
Blazars' non-thermal emission shows rapid variability across all wavelengths, so spectral energy distributions (SEDs) built from quasi-simultaneous data are crucial for revealing t…
On the origin of a possible hard VHE spectrum from M87 discovered by LHAASO
Rui Xue, Jia-Chun He, Dingrong Xiong +1
Recent LHAASO observations hint at potential spectral hardening around 20 TeV in M87's very high energy (VHE) emission, suggesting a possible new radiation component. In this work,…
Time-Dependent Leptohadronic Modeling of Markarian 421
Rui Xue, Ze-Rui Wang, Hai-Bin Hu
Due to its proximity, Markarian 421 is one of the most extensively studied jetted active galactic nuclei. Its spectral energy distribution and light curve are widely studied, servi…
Hadronuclear interactions in AGN jets as the origin of the diffuse high-energy neutrino background
Rui Xue, Ze-Rui Wang, Jagdish C. Joshi +1
The origin of diffuse high-energy neutrinos from TeV to PeV energies detected by IceCube Observatory remains a mystery. In our previous work, we have shown that hadronuclear (p-p)…
Constraining the Physical Parameters of Blazars Using the Seed Factor Approach
Chang-Bin Deng, Yong-You Shi, Yu-Jie Song +4
The discovery that blazars dominate the extra-galactic γ-ray sky is a triumph in the Fermi era. However, the exact location of γ-ray emission region still remains in debate. Low-sy…
The physical properties of Fermi-4LAC low-synchrotron-peaked BL Lac objects
Hai-Bin Hu, Hai-Qin Wang, Rui Xue +2
Previous studies on the fitting of spectral energy distributions (SEDs) often apply the external-Compton process to interpret the high-energy peak of low-synchrotron-peaked (LSP) B…
Understanding the phenomenological and intrinsic blazar sequence using a simple scaling model
Zhu-Jian Wan, Rui Xue, Ze-Rui Wang +2
The blazar sequence, including negative correlations between radiative luminosity and synchrotron peak frequency , and between Compton dominance and , is wi…
A multi-zone view on the multi-wavelength emission of blazars
Ruo-Yu Liu, Rui Xue, Ze-Rui Wang +2
In this work, a time-dependent modeling is developed to study the emission properties of blazars in the low state. Motivated by various observations, we speculate and assume that n…
