A physical understanding of how reionization suppresses accretion onto dwarf halos
Yookyung Noh, Matthew McQuinn
We develop and test with cosmological simulations a physically motivated theory for how the interplay between gravity, pressure, cooling, and self-shielding set the redshift--depen…
Disentangling correlated scatter in cluster mass measurements
Yookyung Noh, J. D. Cohn
The challenge of obtaining galaxy cluster masses is increasingly being addressed by multiwavelength measurements. As scatters in measured cluster masses are often sourced by proper…
The geometry of the filamentary environment of galaxy clusters
Yookyung Noh, J. D. Cohn
We construct a filament catalogue using an extension of the halo based filament finder of Zhang et al.(2009), in a 250 Mpc/h side N-body simulation, and study the properties of fil…
Reconstructing baryon oscillations
Yookyung Noh, Martin White, Nikhil Padmanabhan
The baryon acoustic oscillation (BAO) method for constraining the expansion history is adversely affected by non-linear structure formation, which washes out the correlation functi…
Evolution of the Pancaking Effect in a LCDM Cosmology
Yookyung Noh, Jounghun Lee
We explore the evolution of the large-scale anisotropy in the velocity field caused by the gravitational pancaking effect assuming a LCDM universe. The Millennium Run halo catalogs…
The Anisotropy in the Galaxy Velocity Field Originated from the Gravitational Pancaking Effect
Yookyung Noh, Jounghun Lee
We analyze the Millennium run semi-analytic galaxy catalog to explore quantitatively the gravitational pancaking effect on the orientation of galaxy velocity field. We first calcul…
