Galactic Center gamma-ray excess from a generic triaxial halo
Leo Qiyuan Hu, Ilias Cholis, Yi-Ming Zhong
Recent studies of Galactic surveys, such as Gaia, have revealed that the Milky Way's gravitational potential comes from a matter distribution that is triaxial and rotated with resp…
Quasi-Simultaneous Broadband Spectral Energy Distributions of a Sample of Fermi Blazars -- I. Correlation Results
Yi Zhong, Zhujian Wan, Rui Xue +3
Blazars' non-thermal emission shows rapid variability across all wavelengths, so spectral energy distributions (SEDs) built from quasi-simultaneous data are crucial for revealing t…
Entanglement probes of gravitational Kaluza-Klein spectra: signal hierarchy and model discrimination
Yi Zhong, Tao-Tao Sui, Ke Yang
Quantum-gravity-induced entanglement of masses (QGEM) provides a phase-sensitive probe of extra-dimensional corrections to the Newtonian potential at submillimeter separations. We…
Probing Collapsed Dark Matter Halos with Fast Radio Bursts
Yuxuan He, Weiyang Wang, Chen Zhang +1
Observations of ultra-dense substructures in strong lensing systems challenge the standard cosmological model at small scales. Self-interacting dark matter (SIDM), as an alternativ…
Implications of the KM3NeT Ultrahigh-energy Event on Neutrino Self-interactions
Yuxuan He, Jia Liu, Xiao-Ping Wang +1
Neutrino self-interactions (SI) mediated by light bosonic particles can produce characteristic spectral dips in astrophysical neutrino fluxes, thereby altering the expected ene…
The HalfDome Multi-Survey Cosmological Simulations: N-body Simulations
Adrian E. Bayer, Yici Zhong, Zack Li +3
Upcoming cosmological surveys have the potential to reach groundbreaking discoveries on multiple fronts, including the neutrino mass, dark energy, and inflation. Most of the key sc…
