3D Genus Topology of Luminous Red Galaxies
J. Richard Gott, Yun-Young Choi, Changbom Park +1
We measure the 3D genus topology of large scale structure using Luminous Red Galaxies (LRGs) in the Sloan Digital Sky Survey and find it consistent with the Gaussian random phase i…
The Horizon Run N-body Simulation: Baryon Acoustic Oscillations and Topology of Large Scale Structure of the Universe
Juhan Kim, Changbom Park, J. Richard Gott +1
In support of the new Sloan III survey, which will measure the baryon oscillation scale using the luminous red galaxies (LRGs), we have run the largest N-body simulation to date us…
Environment and mass dependencies of galactic spin parameter: cosmological simulations and SDSS galaxies compared
B. Cervantes-Sodi, X. Hernandez, Changbom Park +1
We use a sample of galaxies from the Sloan Digital Sky Survey (SDSS) to search for correlations between the spin parameter and the environment and mass of galaxies. In order to…
A Subhalo-Galaxy Correspondence Model of Galaxy Formation
Juhan Kim, Changbom Park, Yun-Young Choi
We propose a model of allocating galaxies in cosmological N-body simulations. we identify each subhalo with a galaxy, and assign luminosity and morphological type assuming that the…
Environment and mass dependencies of galactic spin parameter: cosmological simulations and observed galaxies compared
B. Cervantes-Sodi, X. Hernandez, Changbom Park +1
We use a sample of galaxies from the Sloan Digital Sky Survey (SDSS) to search for correlations between the spin parameter and the environment and mass of galaxies. In order to…
Topology of structure in the Sloan Digital Sky Survey: model testing
J. Richard Gott, D. Clay Hambrick, Michael S. Vogeley +6
We measure the three-dimensional topology of large-scale structure in the Sloan Digital Sky Survey (SDSS). This allows the genus statistic to be measured with unprecedented statist…
