Multi-Messenger and Paleo-Detector Probes of the LZ Dark Matter Signal
Meiwen Yang, Quan-feng Wu, Yue-Lin Sming Tsai +1
The LUX-ZEPLIN collaboration recently reported a excess at a nuclear recoil energy of , challenging the standard elastic WIMP paradigm. We show that a lepto…
A Unified Bogoliubov Approach to Primordial Gravitational Waves: From Inflation to Reheating
Yubing Wang, Quan-feng Wu, Xun-Jie Xu
We present an effective numerical method that can be used to straightforwardly calculate the full spectrum of primordial gravitational waves produced during inflation and reheating…
Probing Bose-enhanced Inflaton Decay with Gravitational Waves
Nicolás Bernal, Quan-feng Wu, Xun-Jie Xu +1
We investigate cosmic reheating dynamics in the presence of a transient condensate formed by bosonic decay products of the inflaton. We show that the emergence of such a condensate…
Primordial Black Holes Evaporating before Big Bang Nucleosynthesis
Quan-feng Wu, Xun-Jie Xu
Primordial black holes (PBHs) formed from the collapse of density fluctuations provide a unique window into the physics of the early Universe. Their evaporation through Hawking rad…
No Hiding in the Dark: Cosmological Bounds on Heavy Neutral Leptons with Dark Decay Channels
P. S. Bhupal Dev, Quan-feng Wu, Xun-Jie Xu
Heavy neutral leptons (HNLs) are well-motivated new physics candidates. The mixing of sub-GeV HNLs with active neutrinos is severely constrained by cosmology. In particular, the su…
Pre-thermalized Gravitational Waves
Nicolás Bernal, Quan-feng Wu, Xun-Jie Xu +1
We investigate a novel gravitational wave (GW) production mechanism from gravitons generated during the pre-thermal phase of cosmic reheating, where the energy density is dominated…
