System noise temperature measurements of a 19-element phased array feed
Shenghua Yu, Dejian Ding, Hongwei Xi +25
We present multi-epoch system noise temperature measurements of a 19 element hexagonal room-temperature phased array feed (PAF) using a modified Y-factor method. A Python-based pip…

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…

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…
