Does the high-energy AMS-02 positron flux originate from the dark matter density spikes around nearby black holes?
Man Ho Chan, Chak Man Lee
Recent measurements made by the Alpha Magnetic Spectrometer (AMS) have detected accurate positron flux for energy range 1-1000 GeV. The energy spectrum can be best described by two…

Identifying dark matter signals by the radio continuum spectral data of the cool-core cluster RX J1720.1+2638
Man Ho Chan, Chak Man Lee
Investigating the signals of dark matter annihilation is one of the most popular ways to understand the nature of dark matter. In particular, many recent studies are focussing on u…
