On Physical Scales of Dark Matter Halos
Marcel Zemp
It is common practice to describe formal size and mass scales of dark matter halos as spherical overdensities with respect to an evolving density threshold. Here, we critically inv…
Structure Finding in Cosmological Simulations: The State of Affairs
Alexander Knebe, Frazer R. Pearce, Hanni Lux +32
The ever increasing size and complexity of data coming from simulations of cosmic structure formation demands equally sophisticated tools for their analysis. During the past decade…
Revisiting The First Galaxies: The epoch of Population III stars
Alexander L. Muratov, Oleg Y. Gnedin, Nickolay Y. Gnedin +1
We investigate the transition from primordial Population III (Pop III) star formation to normal Pop II star formation in the first galaxies using new cosmological hydrodynamic simu…
Revisiting The First Galaxies: The effects of Population III stars on their host galaxies
Alexander L. Muratov, Oleg Y. Gnedin, Nickolay Y. Gnedin +1
We revisit the formation and evolution of the first galaxies using new hydrodynamic cosmological simulations with the ART code. Our simulations feature a recently developed model f…
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…
Halo Retention and Evolution of Coalescing Compact Binaries in Cosmological Simulations of Structure Formation: Implications for Short Gamma-Ray Bursts
Marcel Zemp, Enrico Ramirez-Ruiz, Jürg Diemand
Merging compact binaries are the one source of gravitational radiation so far identified. Because short-period systems which will merge in less than a Hubble time have already been…
