Probing Primordial Power Spectrum and Non-Gaussianities With Fast Radio Bursts
Zhiyao Lu, Lian-Tao Wang, Huangyu Xiao
We use the precision measurements of the arrival time differences of the same fast radio burst (FRB) source along multiple sightlines to measure the primordial power spectrum and N…

Monopole Catalyzed Baryogenesis with a angle
T. Daniel Brennan, Lian-Tao Wang, Huangyu Xiao
Monopoles are generally expected in Grand Unified Theories (GUTs) where they can catalyze baryon decay at an unsuppressed rate by the Callan-Rubakov effect. For the first time, we…

Detecting Axion Dark Matter with Black Hole Polarimetry
Xucheng Gan, Lian-Tao Wang, Huangyu Xiao
The axion, as a leading dark matter candidate, is the target of many ongoing and proposed experimental searches based on its coupling to photons. Ultralight axions that couple to p…
