Mapping the Real Space Distributions of Galaxies in SDSS DR7: II. Measuring the growth rate, clustering amplitude of matter and biases of galaxies at redshift

Feng Shi, Xiaohu Yang, Huiyuan Wang +9

We extend the real-space mapping method developed in Shi et at. (2016) so that it can be applied to flux-limited galaxy samples. We use an ensemble of mock catalogs to demonstrate…

ELUCID IV: Galaxy Quenching and its Relation to Halo Mass, Environment, and Assembly Bias

Huiyuan Wang, H. J. Mo, Sihan Chen +17

We examine the quenched fraction of central and satellite galaxies as a function of galaxy stellar mass, halo mass, and the matter density of their large scale environment. Matter…

Sussing Merger Trees: A proposed Merger Tree data format

Peter A. Thomas, Julian Onions, Dylan Tweed +13

We propose a common terminology for use in describing both temporal merger trees and spatial structure trees for dark-matter halos. We specify a unified data format in HDF5 and pro…

Haloes gone MAD: The Halo-Finder Comparison Project

Alexander Knebe, Steffen R. Knollmann, Stuart I. Muldrew +34

[abridged] We present a detailed comparison of fundamental dark matter halo properties retrieved by a substantial number of different halo finders. These codes span a wide range of…

SubHaloes going Notts: The SubHalo-Finder Comparison Project

Julian Onions, Alexander Knebe, Frazer R. Pearce +14

We present a detailed comparison of the substructure properties of a single Milky Way sized dark matter halo from the Aquarius suite at five different resolutions, as identified by…

The Population of Giant Clumps in Simulated High-z Galaxies: In-situ and Ex-situ, Migration and Survival

Nir Mandelker, Avishai Dekel, Daniel Ceverino +3

We study the properties of giant clumps and their radial gradients in high- disc galaxies using AMR cosmological simulations. Our sample consists of 770 snapshots in the redshif…
