A Comprehensive Study of WIMP Models Explaining the Fermi-LAT Galactic Center Excess
Chuiyang Kong, Mattia Di Mauro
The Galactic Center excess (GCE) of GeV rays may hint at dark matter (DM), yet its origin remains debated. Motivated by this, we survey weakly interacting massive particle (WI…

Merger-induced disturbance and temporal signatures in galaxy clusters: a combined phase space and photometric analysis
Chuiyang Kong, Ian Dell'Antonio
We present a physically interpretable framework to quantify dynamical disturbances in galaxy clusters using projected two-dimensional phase-space information. Based on the TNG-Clus…
