Theory of Astroparticle Sources

Study the origin of astroparticles using numerical simulations

Recent work: Interpretation of IceCube’s Galactic Plane observation 

 

Observation with HAWC

The High-Altitude Water Cherenkov Gamma-ray Observatory located near Puebla, Mexico is a wide-field TeV-PeV gamma-ray detector. We analyze the HAWC data to reveal of looks of the cosmos at the highest photon energies.

Recent work: TeV halo around a radio-quiet pulsar, Cygnus Cocoon, SS 433

IceCube data analysis

The IceCube Observatory at the geographic South Pole opens a new window to “see” the universe with high-energy neutrinos. We hunt for astrophysical sources in the IceCube data with efficient source finding algorithms.

Recent work: neutrino source searches with two-point cross correlation, with event pairs

Studies with Fermi-LAT

As an affiliated member of the Fermi Collaboration, Ke uses the Fermi Large Area Telescope for multi-messenger followup studies.

Recent work: a PeVatron supernova remnant, Joint analysis of HAWC and Fermi-LAT observations of SS433
