Constraining Primordial Black Hole Fraction at the Galactic Centre using radio observational data
Man Ho Chan, Chak Man Lee
Recent gamma-ray and cosmic-ray observations have put strong constraints on the amount of primordial black holes (PBHs) in our universe. In this article, we use the archival radio…
Constraining the spin-independent elastic scattering cross section of dark matter using the Moon as a detection target and the background neutrino data
Man Ho Chan, Chak Man Lee
Our Moon is a natural giant direct-detection target for constraining dark matter. By considering the dark matter capture rate of the Moon, we obtain some constraints of the spin-in…
A possible radio signal of annihilating dark matter in the Abell 4038 cluster
Man Ho Chan, Chak Man Lee
In the past decade, some telescopes (e.g. Fermi-LAT, AMS and DAMPE) were launched to detect the signals of annihilating dark matter in our Galaxy. Although some excess of gamma ray…
Fitting dark matter mass with the radio continuum spectral data of the Ophiuchus cluster
Man Ho Chan, Chak Man Lee
Recent gamma-ray and anti-proton analyses suggest that dark matter with mass GeV annihilating via channel can explain the Galactic center GeV gamma-ray excess…
Origin of the DAMPE 1.4 TeV peak
Man Ho Chan, Chak Man Lee
Recent accurate measurements of cosmic ray electron flux by the Dark Matter Particle Explorer (DAMPE) reveal a sharp peak structure near 1.4 TeV, which is difficult to explain by s…
