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…

A strong falsification of the universal radial acceleration relation in galaxies
Man Ho Chan
In the past few decades, many studies revealed that there exist some apparent universal relations which can describe the dynamical properties in galaxies. In particular, the radial…
