Shape-Preserving Evolution of the Global Ultraviolet Quasar Luminosity Function to
Wenjie Wang, Zunli Yuan, Yu Luo +1
We present a global unbinned-likelihood analysis of the rest-frame ultraviolet (UV) quasar luminosity function (QLF) over , using a final analysis sample of 70,960…
Multi-Period Fermi-LAT and LHAASO Constraints on Axion-Like Particles from Mrk 421 via Profile Likelihood with Gaussian Copula Correlation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +9
We present a joint multi-period analysis of axion-like particles (ALPs) using five sets of simultaneous Fermi-LAT and LHAASO observations of the TeV blazar Mrk~421. Photon-ALP osci…
CosmicWeb-21cm array: A New Radio Observation Array Design for 21cm Cosmology
Jiancheng Wang, Jirong Mao, Xiangming Cheng +10
This paper presents the CosmicWeb-21cm array, a novel radio interferometer designed to overcome the key challenges in 21 cm cosmology. Its core innovations include: (1) a multi-sca…
A flexible method for estimating luminosity functions via Kernel Density Estimation -- III. Extending to Multiple Flux-Limited Samples
Zunli Yuan, Chuanqi Li, Wenjie Wang +2
As the third paper in a series regarding the estimation of luminosity functions (LFs) via kernel density estimation (KDE), we present a further generalization of our framework by e…
Revisiting Very High Energy Gamma-Ray Absorption in Cosmic Propagation under the Combined Effects of Axion-Like Particles and Lorentz Invariance Violation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +9
Very-high-energy (VHE; GeV) gamma rays are expected to experience strong attenuation during cosmological propagation due to electron-positron pair production on the…
Optical Monitoring and Long-term Optical Spectral Variability of BL Lacertae Object S5 0716+714
Huai-Zhen Li, Di-Fu Guo, Long-Hua Qin +7
We present photometric observations of the BL Lacertae object S5 0716+714 with a temporal resolution of 120 s in the Sloan i' and r' bands. These observations were conducted using…
The fundamental plane of blazars based on the black hole spin-mass energy
Xu Zhang, Dingrong Xiong, Quangui Gao +4
We examine the fundamental plane of 91 Blazars which include FSRQs and BL Lacs with known X-ray luminosity (), radio luminosity (), and black hole mass measurements ($M…
Constraints on Extragalactic Background Light using TeV Observations of BL Lacertae objects
Longhua Qin, Jiancheng Wang, Quangui Gao +5
The extragalactic background light (EBL) in the IR to UV bands partly absorbs very high energy (VHE, 100GeV) ray photons travelling over cosmological distances via pai…
Studies of Extragalactic Background Light with TeV BL Lac Objects
Longhua Qin, Jiancheng Wang, Quangui Gao +4
Very high energy (VHE; 100GeV) ray from cosmological distances are attenuated by the extragalactic background light (EBL) in the IR to UV band. By contrasting measured…
Using the Markov Chain Monte Carlo method to study the physical properties GeV-TeV BL Lac objects
Longhua Qin, Jiancheng Wang, Chuyuan Yang +3
We fit the spectral energy distributions (SEDs) of 46 GeV - TeV BL Lac objects in the frame of leptonic one-zone synchrotron self-Compton (SSC) model and investigate the physical p…
Constraining the redshifts of TeV BL Lac objects
Longhua Qin, Jiancheng Wang, Dahai Yan +3
We present a model-dependent method to estimate the redshifts of three TeV BL Lac objects (BL Lacs) through fltting their (quasi-) simultaneous multi-waveband spectral energy distr…
A mixture evolution scenario of the AGN radio luminosity function. II. Do low- and high-power radio-loud AGNs evolve differently?
Zunli Yuan, Jiancheng Wang, Ming Zhou +2
Following previous work, we further confirm that the cosmic evolution of steep-spectrum radio-loud AGNs (active galactic nuclei) can be reproduced by a simple combination of densit…
