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…
What if PSR J1910-5959A is an observable self-lensing binary?
Man Ho Chan, Chak Man Lee
In a binary, when the orbital plane of the companion star is almost edge-on along the line-of-sight direction, this would produce an observable self-gravitational lensing effect, w…
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…
A severe challenge to the MOND phenomenology in our Galaxy
Man Ho Chan, Ka Chung Law
Modified Newtonian Dynamics (MOND) is one of the most popular alternative theories of dark matter to explain the missing mass problem in galaxies. Although it remains controversial…
What if planet 9 has satellites?
Man Ho Chan
In the past decade, numerical simulations started to reveal the possible existence of planet 9 in our solar system. The planet 9 scenario can provide an excellent explanation to th…
