Constraining the axion-photon coupling using radio data of the Bullet Cluster
Man Ho Chan
Axion is one of the most popular candidates of the cosmological dark matter. Recent studies considering the misalignment production of axions suggest some benchmark axion mass rang…
Model-independent constraints on ultra-light dark matter from the SPARC data
Man Ho Chan, Chu Fai Yeung
Ultra-light dark matter (ULDM) is currently one of the most popular classes of cosmological dark matter. The most important advantage is that ULDM with mass eV ca…
Improved Lemaitre-Tolman model and the mass and turn-around radius in group of galaxies
Antonino Del Popolo, Maksym Deliyergiyev, Man Ho Chan
We extended the modified Lemaitre-Tolman model taking into account the effect of angular momentum and dynamical friction. The inclusion of these quantities in the equation of motio…
Analysing the radio flux density profile of the M31 galaxy: a possible dark matter interpretation
Man Ho Chan, Chu Fai Yeung, Lang Cui +1
Some recent studies have examined the gamma-ray flux profile of our Galaxy to determine the signal of dark matter annihilation. However, the results are controversial and no confir…
