Galactic Halos Derived from LambdaCDM Cosmology Simulation and their Red-Shift Evolution
Hung-Yu Jian, Chia-Hung Chien, Tzihong Chiueh
Galaxies can form in a sufficiently deep gravitational potential so that efficient gas cooling occurs. We estimate that such potential is provided by a halo of mass $M \gtsim M_{c}…

How Well Can Weak Lensing Measure the Mass of Galaxy Clusters?
Jun-Mein Wu, Keiichi Umetsu, Chia-Hung Chien +1
The technique of weak-lensing aperture mass densitometry, so called the zeta-statistic, has recently been popular in actual observations for measurement of individual cluster mass.…
