Non self-similar Luminosity-temperature relation and dynamical friction
Antonino Del Popolo, Morgan Le Delliou, Man Ho Chan
Extending the results of a previous paper \citep{DelPopolo2005}, by taking into account the role of dynamical friction, we recovered the luminosity-temperature relation (LTR). Whil…
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…
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…
A tight correlation between the enclosed gravitational mass and hot gas mass in galaxy clusters at intermediate radii
Man Ho Chan
Many studies point out that there exists some tight correlations between dark matter and baryonic matter at different radii in galaxies. However, similar tight correlations can onl…
A universal constant for dark matter-baryon interplay
Man Ho Chan
Recent studies point out that there exists some rough scaling relations for dark matter and some tight connections between dark matter and baryons. However, most of the relations a…
Sterile neutrino fits to dark matter mass profiles in the Milky Way and in galaxy clusters
Man Ho Chan, Robert Ehrlich
In several recent papers it was claimed that SN 1987A data supports the existence of 4.0 eV and 21.4 eV active neutrino mass eigenstates, and it was shown that such large masses co…
