Is the mysterious {\it Punctum} a primordial black hole?
Man Ho Chan
A recent study has discovered a highly polarized millimeter continuum source called {\it Punctum} located at the central region of NGC 4945 which doesn't fit any known category. Ap…
The exotic black hole-neutron star binaries in our Galaxy
Man Ho Chan
It has been suggested that there are black hole-neutron star (BH-NS) binaries in our Galaxy. However, despite the effort of intensive radio search for decades, none of…
Indirect Evidence for Dark Matter Density Spikes around Stellar-Mass Black Holes
Man Ho Chan, Chak Man Lee
It has been suggested for a long time that dark matter would form a density spike around a black hole. However, no promising evidence has been observed so far to verify this theore…
Constraining annihilating dark matter mass by the radio continuum spectral data of a high-redshift galaxy cluster
Man Ho Chan, Chak Man Lee, C. -Y. Ng +1
In the past decade, the properties of annihilating dark matter models were examined by various kinds of data, including the data of gamma rays, radio waves, X-ray, positrons, elect…
The decaying and scattering properties of the (2380) hexaquark Bose Einstein Condensate dark matter
Man Ho Chan
Recently, a study has shown that the Bose Einstein Condensates formed by the (2380) hexaquarks ((2380)-BECs) can be thermally produced in the early universe and they are…
A new target object for constraining annihilating dark matter
Man Ho Chan
In the past decade, gamma-ray observations and radio observations of our Milky Way and the Milky Way dwarf spheroidal satellite galaxies put very strong constraints on annihilation…
