Galaxy cluster formation from the large-scale structure: a case study of the Abell 2125 complex at z=0.247
C153 SW cD
2014/12/24
The structure of the universe is believed to have formed by clustering hierarchically from small to large scales. Much of this evolution occurs very slowly but at a few special times more rapid, viole...
S0 galaxies are often thought to be passively evolved from spirals after star formation is quenched. To explore what is actually occurring in such galaxies, we present a multi-wavelength case study of...
A Study of Optical Observing Techniques for Extra-Galactic Supernova Remnants: Case of NGC 300
Optical Observing Techniques Extra-Galactic Supernova Remnants NGC 300
2012/2/21
We present the results of a study of observational and identification techniques used for surveys and spectroscopy of candidate supernova remnants (SNRs) in the Sculptor Group galaxy NGC 300. The goal...

2011/9/26
The vivid image of R-W metric for the case of hypersphere is given; The hypersphere is proposed as the only model for the physical universe; The cosmic radius R(t) may be defined as a cosmic broad tim...
ON ORBITS FOR A PARTICULAR CASE OF AXIAL SYMMETRY
Galaxy: kinematics and dynamics Miyamoto and Nagai
2010/10/29
A particular case of steady state and axial symmetry -the potential formula proposed by Miyamoto and Nagai - is studied. A number of orbits of a bound test particle is determined numerically, with bot...
