The Mass Function of Void Groups as a Probe of the Primordial non-Gaussianity
Hyunmi Song, Jounghun Lee
The primordial non-Gaussianity signal, if measured accurately, will allow us to distinguish between different candidate models for the cosmic inflation. Since the galaxy groups loc…
Information Content in the Galaxy Angular Power Spectrum from the Sloan Digital Sky Survey and Its Implication on Weak Lensing Analysis
Jounghun Lee, Ue-Li Pen
We analyze the photometric redshift catalog of the Sloan Digital Sky Survey Data Release 5 (SDSS DR5) to estimate the Fisher information in the galaxy angular power spectrum with t…
Connecting the Physical Properties of Galaxies with the Overdensity and Tidal Shear of the Large-Scale Environment
Jounghun Lee, Cheng Li
We have examined the correlations between the large-scale environment of galaxies and their physical properties, using a sample of 28,354 nearby galaxies drawn from the Sloan Digit…
The Variation of Galaxy Morphological Type with the Shear of Environment
Jounghun Lee, Bomee Lee
Recent N-body simulations have shown that the assembly history of galactic halos depend on the density of large-scale environment. It implies that the galaxy properties like age an…
The Size Distribution of Void Filaments in a LCDM Cosmology
Daeseong Park, Jounghun Lee
The size distribution of mini-filaments in voids has been derived from the Millennium Run halo catalogs at redshifts z=0,0.5,1 and 2. It is assumed that the primordial tidal field…
