An analytical model for the history of cosmic star formation
Lars Hernquist, Volker Springel
We use simple analytic reasoning to identify physical processes that drive the evolution of the cosmic star formation density in cold dark matter universes. Based on our analysis,…
The phase-space structure of cold dark-matter halos: Insights into the Galactic halo
Amina Helmi, Simon D. M. White, Volker Springel
We study the formation of the Milky Way's halo in a CDM cosmology by scaling down a high resolution simulation of the formation of a cluster of galaxies. We determine how much p…
Cosmological SPH simulations: A hybrid multi-phase model for star formation
Volker Springel, Lars Hernquist
We present a model for star formation and supernova feedback that describes the multi-phase structure of star forming gas on scales that are typically not resolved in cosmological…
The history of star formation in a LCDM universe
Volker Springel, Lars Hernquist
Employing hydrodynamic simulations of structure formation in a LCDM cosmology, we study the history of cosmic star formation from the "dark ages" at redshift z~20 to the present. I…
Simulating the Sunyaev-Zel'dovich effect(s): including radiative cooling and energy injection by galactic winds
Martin White, Lars Hernquist, Volker Springel
We present results on the thermal and kinetic Sunyaev-Zel'dovich (SZ) effects from a sequence of high resolution hydrodynamic simulations of structure formation, including cooling,…
High redshift galaxies and the Lyman-alpha forest in a CDM universe
Rupert A. C. Croft, Lars Hernquist, Volker Springel +2
We use a cosmological hydrodynamic simulation of a cold dark matter universe to investigate theoretically the relationship between high redshift galaxies and the Lyman=alpha forest…
