GW231123: False Massive Graviton Signatures from Unmodeled Point-Mass Lensing
Baoxiang Wang, Tao Yang
GW231123 is the strongest current candidate for a lensed gravitational wave event and a unique case for testing how point-mass lensing affects propagation-based tests of gravity. I…

Impact of higher-order modes on eccentricity measurement in binary black hole gravitational waves
Honglue Tang, Jinzhao Yang, Baoxiang Wang +1
We investigate the systematic biases in measuring orbital eccentricity for binary black hole (BBH) mergers that arise when higher-order modes (HOMs) of gravitational waves are negl…

Constraining scalar-tensor theories from higher harmonics with GW230529
Baoxiang Wang, Tao Yang
The Advanced LIGO and Virgo collaborations recently detected a gravitational wave event, GW230529\_181500, during the fourth observing run, which is most plausibly attributed to th…
