Measuring peculiar velocity and tomographic redshift dipole with DESI DR1 catalogs
Yi-Wen Wu, Jun-Qing Xia
The so-called ``cosmic dipole tension'' challenges the Cosmological Principle by positing a discrepancy between the Solar System's peculiar velocity inferred from the Cosmic Microw…
Search for quasar pairs with Gaia astrometric data. II. Photometric redshift prediction with machine learning for the MGQPC catalogue
Xingyu Zhu, Qihang Chen, Liang Jing +4
The identification of physically associated kiloparsec-scale quasar pairs is important for understanding galaxy evolution, the growth of supermassive black holes, and their co-evol…
Photometric Redshift PDFs via Neural Network Classification for DESI Legacy Imaging Surveys and Pan-STARRS
Da-Chuan Tian, Zhong-Lue Wen, Jun-Qing Xia
We present a neural network classification (NNC) method for photometric redshift estimation that produces well-calibrated redshift probability density functions (PDFs). The method…
A Quasar Pair Sample Compiled from DESI DR1
Liang Jing, Qihang Chen, Zhuojun Deng +4
Interacting quasar pairs (QPs, either dual or binary) provide crucial insights into galaxy mergers, black hole growth, and large-scale structure formation. The current literature r…
Measuring Cosmic Growth Rate with CSST Spectroscopic Survey and Fast Radio Burst
Shi-Yuan Wang, Jun-Qing Xia
The cosmic growth rate, which is related to peculiar velocity and is a primary scientific objective of galaxy spectroscopic surveys, can be inferred from the Redshift Space Distort…
Constraints on Evolutions of Fundamental Constants from Clustering of Fast Radio Burst Dispersion Measure
Shi-Yuan Wang, Jun-Qing Xia
Constrained measurements of fundamental physical constants using astronomical observational data represent a powerful method for investigating potential new physics. In particular,…
Do JWST reionization (optical depth) puzzle, cosmological tensions, and CMB anomalies imply Harrison-Zel'dovich spectrum?
Hao-Hao Li, Xin-zhe Zhang, Taotao Qiu +1
The James Webb Space Telescope (JWST) has observed massive galaxies at high redshifts, which implies an earlier epoch of reionization (EoR) compared with the cosmic microwave backg…
Probing Cosmic Isotropy with the FAST All Sky HI Survey
Yi-Wen Wu, Jun-Qing Xia
This paper leverages the first released catalog from the FAST All Sky \textsc{Hi} Survey (FASHI) to examine the hypothesis of cosmic isotropy in the local Universe. Given the desig…
COSMIC: A Galaxy Cluster Finding Algorithm Using Machine Learning
Da-Chuan Tian, Yang Yang, Zhong-Lue Wen +1
Building a comprehensive catalog of galaxy clusters is a fundamental task for the studies on the structure formation and galaxy evolution. In this paper, we present COSMIC (Cluster…
