Tracing cosmic star formation history through radio continuum spectral energy distribution and non-thermal emission
Fangxia An, Fatemeh S. Tabatabaei, Nick Seymour +11
The paper reviews how radio continuum emission, especially mid‑radio (1–10 GHz) luminosity and spectral shape, can be used as a dust‑unbiased tracer of star formation rates and the…
Improving Radio Source Count Estimation Using Kernel Density Estimation
Luozhenhan Liu, Zunli Yuan, Wenjie Wang +1
Radio source counts provide a fundamental census of cosmic radio emission, yet their estimation is usually based on coarse histograms that suffer from bin-choice bias, boundary eff…
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…
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 the 150 MHz Radio Luminosity Function of Star-Forming Galaxies with LOFAR Deep Fields through a Refined Statistical Framework
Wenjie Wang, Zunli Yuan, Hongwei Yu +3
We present a comprehensive analysis of the 150~MHz radio luminosity function (LF) of star-forming galaxies (SFGs) using deep observations from the LOFAR Two-metre Sky Survey in the…
Joint Multi-Period Fermi-LAT and LHAASO Constraints on Axion-Like Particles from Mrk 421 Using Profile Likelihood with Gaussian Copula Correlation
Longhua Qin, Jiancheng Wang, Chuyuan Yang +8
We propose a joint multi-epoch profile-likelihood analysis of axion-like particles (ALPs) using five sets of simultaneous Fermi-LAT and LHAASO observations of the TeV blazar Mrk 42…
