The first robust evidence showing a dark matter density spike around the supermassive black hole in OJ 287
Man Ho Chan, Chak Man Lee
Black hole dynamics suggests that dark matter would re-distribute near a supermassive black hole to form a density spike. However, no direct evidence of dark matter density spike a…

Constraining annihilating dark matter using the multi-frequency radio flux profiles of the M33 galaxy
Man Ho Chan, Chak Man Lee, Lang Cui +2
Radio data can give stringent constraints for annihilating dark matter. In general, radio observations can detect very accurate radio flux density with high resolution and differen…

Crossing the dark matter soliton core: a possible reversed orbital precession
Man Ho Chan, Chak Man Lee
The ultra-light dark matter (ULDM) model has become a popular dark matter scenario nowadays. The mass of the ULDM particles is extremely small so that they can exhibit wave propert…
