Gravitational Lensing Predictions from Wave Simulations of Fuzzy Dark Matter
Jiajun Zhou, Zhengxiang Li, Amruth Alfred +3
In the cold dark matter paradigm, ultra-light particles are emerging as strong contenders to conventional massive particles. A unique prediction of dark matter comprising such ultr…
FRB cosmology with the RM-PRS Luminosity Correlation
Ran Gao, He Gao, Zhengxiang Li +1
Fast Radio Bursts (FRBs) have emerged as a powerful tool for cosmological studies, particularly through the dispersion measure-redshift () relation. This work propos…
The EMPI Code for Plasma-Induced Effects on Radio Waves I: Non-Magnetized Media and Applications to Fast Radio Bursts
Nan Xu, He Gao, Yuan-Pei Yang +4
Electromagnetic waves undergo modifications as they propagate through plasma. We present EMPI (ElectroMagnetic-wave Plasma Interaction), a three-dimensional numerical framework des…
Lensed fast radio bursts as a probe of time-varying gravitational potential induced by wave dark matter
Ran Gao, Shuxun Tian, Zhengxiang Li +4
Ultralight bosonic wave dark matter (DM) is preponderantly contesting the conventional cold DM paradigm in predicting diverse and rich phenomena on small scales. For a DM halo made…
