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…
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…
