Revealing the - Correlation among Coalescing Binary Black Holes and Tentative Evidence for AGN-driven Hierarchical Mergers
Yin-Jie Li, Yuan-Zhu Wang, Shao-Peng Tang +2
The paper analyzes the correlation between effective spin (χ_eff) and mass ratio (q) in LIGO-Virgo-KAGRA binary black hole detections, finding that the overall trend can be explain…
New measurement at Redshift = 0.12 with DESI Data Release 1
Ze-fan Wang, Lei Lei, Yi-zhong Fan
The Hubble parameter () is a function of the redshift and a reliable measurement is very important to understand the expansion history of the Universe. In this work, we perfo…
GW231123: Likely a product of successive mergers from stellar-mass black holes
Yin-Jie Li, Shao-Peng Tang, Ling-Qin Xue +1
GW231123 is an exceptionally massive binary black hole (BBH) merger with unusually high component spins. Such extreme properties challenge conventional stellar evolution models pre…
A dense dark matter core of the subhalo in the strong lensing system JVAS B1938+666
Lei Lei, Yi-Ying Wang, Qiao Li +7
The nature of dark matter remains unknown, motivating the study of fuzzy/wave dark matter (FDM/DM) and self-interacting dark matter (SIDM) as alternative frameworks to address…
Can Dark Stars account for the star formation efficiency excess at very high redshifts?
Lei Lei, Yi-Ying Wang, Guan-Wen Yuan +3
The James Webb Space Telescope (JWST) has recently conducted observations of massive galaxies at high redshifts, revealing a notable anomaly in their star formation efficiency (SFE…
Multi-spectral Sirens: Gravitational-wave Cosmology with (Multi-) Sub-populations of Binary Black Holes
Yin-Jie Li, Shao-Peng Tang, Yuan-Zhu Wang +1
The cosmic expansion rate can be directly measured with gravitational-wave (GW) data of the compact binary mergers by jointly constraining the mass function of the population and t…
