Void Ellipticity Distribution as a Probe of Cosmology
Daeseong Park, Jounghun Lee
Cosmic voids refer to the large empty regions in the universe with a very low number density of galaxies. Voids are likely to be severely disturbed by the tidal effect from the sur…
A Cosmological Mass Function with Broken Hierarchy
Jounghun Lee
We construct an analytic formalism for the mass function of cold dark matter halos, assuming that there is a break in the hierarchical merging process. According to this {\it broke…
The Three Dimensional Structural Shape of the Gravitational Potential in the Local Group
Bomee Lee, Jounghun Lee
The Local Group is a small galaxy cluster with the membership of 62 nearby galaxies including the Milky Way and M31. Although the Local Group has yet to be virialized, it interacts…
On the Environmental Dependence of Galaxy Properties Established by the Initial Cosmological Conditions
Jounghun Lee
We study theoretically how the initial cosmological conditions establish the dependence of galaxy properties on the environment. First, we adopt the linear tidal torque theory acco…
The Alignments of Disk Galaxies with the Local Pancakes
Yookyung Noh, Jounghun Lee
We analyze the Tully catalog of nearby galaxies to investigate the local pancaking effect on the orientation of disk galaxies. We first select only those edge-on disk galaxies in t…
