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…

Hunting Galactic Axion Dark Matter with Gravitationally Lensed Fast Radio Bursts
Ran Gao, Zhengxiang Li, Kai Liao +3
Ultralight axion or axionlike particles are one of the most promising candidates for dark matter because they are a well-motivated solution for the theoretical strong problem…
