A Scaling Relation of the Evolving Tidal Fields in a LCDM Cosmology
Jounghun Lee, Volker Springel
We report the finding of a scaling relation among the cosmic-web anisotropy parameter , the linear density rms fluctuation sigma(r) and the linear growth factor D(z). Using the…
Normalization of the Matter Power Spectrum via the Ellipticity Function of Giant Galaxy Voids from SDSS DR5
Jounghun Lee
The ellipticity function of cosmic voids exhibits strong dependence on the amplitude of the linear matter power spectrum. Analyzing the most recent void catalogs constructed by Fos…
Lagrangian Statistics of Dark Halos in a LCDM Cosmology
Jounghun Lee, Oliver Hahn, Cristiano Porciani
New statistical properties of dark matter halos in Lagrangian space are presented. Tracing back the dark matter particles constituting bound halos resolved in a series of N-body si…
The Anisotropic Two-Point Correlation Functions of the Nonlinear Traceless Tidal Field in the Principal-Axis Frame
Jounghun Lee, Oliver Hahn, Cristiano Porciani
Galaxies on the largest scales of the Universe are observed to be embedded in the filamentary cosmic web which is shaped by the nonlinear tidal field. As an efficient tool to quant…
Detection of Large-Scale Cosmic Magnetic Fields
Jounghun Lee, Ue-Li Pen, A. Russell Taylor +2
Observational evidence for the existence of cosmic magnetic fields in intergalactic space coherent over Mpc scales is presented. Using an unprecedentedly large sample of Faraday ro…
The Bridge Effect of Void Filaments
Daeseong Park, Jounghun Lee
Cosmic filaments play a role of bridges along which matter and gas accrete onto galaxies to trigger star formation and feed central black holes. Here we explore the correlations be…
Probing the Warm Dark Matter with High-z Quasar Luminosity Function
Hyunmi Song, Jounghun Lee
In a warm dark matter (WDM) cosmology, the first objects to form at z>=20 are one dimensional filaments with mean length on the order of the WDM free-streaming scale. Gao and Theun…
