Two-Dimensional Pulsar Distance Inference from Nanohertz Gravitational Waves
Si-Ren Xiao, Ji-Yu Song, Yue Shao +3
Pulsar timing arrays (PTAs) are limited in localizing nanohertz continuous gravitational waves (CGWs) by uncertainties in pulsar distances. We introduce a method to infer pulsar di…
Exploring the Cosmic Dawn through the 21 cm Forest and High-redshift Radio Sources with the SKA
Junsong Cang, Benedetta Ciardi, Barun Maity +12
The 21~cm forest, seen as absorption features in the spectra of distant radio sources, is produced by intervening neutral hydrogen and offers a direct probe of the neutral intergal…
21 cm forest one-dimensional power spectrum as an indirect probe of dark matter particles and primordial black holes
Meng-Lin Zhao, Yue Shao, Sai Wang +1
Understanding the nature of dark matter (DM) particles remains a pivotal challenge in modern cosmology. Current cosmological research on these phenomena primarily utilizes cosmic m…
Analytical modeling of the one-dimensional power spectrum of 21-cm forest based on a halo model method
Yue Shao, Tian-Yang Sun, Meng-Lin Zhao +1
The 21-cm forest, composed of spectral absorption features from high-redshift background radio sources, provides a unique probe for studying small-scale structures during the epoch…
Analyzing the 21cm forest with Wavelet Scattering Transform: Insight into non-Gaussian features of the 21cm forest
Hayato Shimabukuro, Yidong Xu, Yue Shao
The 21cm forest, narrow absorption features in the spectra of high redshift radio sources caused by intervening neutral hydrogen, offers a unique probe of the intergalactic medium…
Ultra-low-frequency gravitational waves from individual supermassive black hole binaries as standard sirens
Ling-Feng Wang, Yue Shao, Si-Ren Xiao +2
Ultra-low-frequency gravitational waves (GWs) generated by individual inspiraling supermassive black hole binaries (SMBHBs) at the centers of galaxies may be detected by pulsar tim…
