The Build-Up of the Hubble Sequence in the COSMOS Field
P. A. Oesch, C. M. Carollo, R. Feldmann +27
We use ~8,600 >5e10 Msol COSMOS galaxies to study how the morphological mix of massive ellipticals, bulge-dominated disks, intermediate-bulge disks, bulge-less disks and irregular…
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…
