Abstract:
Cosmic Dawn II (CoDa II) is a new, fully-coupled
radiation-hydrodynamics simulation of cosmic reionization and galaxy
formation and their mutual impact, to redshift z<6. With 4096^3^
particles and cells in a 94Mpc box, it is large enough to model
global reionization and its feedback on galaxy formation while
resolving all haloes above 10^8^M_sun_. Using the same hybrid
CPU-GPU code RAMSES-CUDATON as CoDa I in Ocvirk et al.
(2016MNRAS.463.1462O), CoDa II modified and re-calibrated the subgrid
star-formation algorithm, making reionization end earlier, at z> 6,
thereby better matching the observations of intergalactic Lyman-alpha
opacity from quasar spectra and electron-scattering optical depth from
cosmic microwave background fluctuations. CoDa II predicts a UV
continuum luminosity function in good agreement with observations of
high-z galaxies, especially at z=6. As in CoDa I, reionization
feedback suppresses star formation in haloes below 2x10^9^M_sun_,
though suppression here is less severe, a possible consequence of
modifying the star-formation algorithm. Suppression is
environment-dependent, occurring earlier (later) in overdense
(underdense) regions, in response to their local reionization times.
Using a constrained realization of LAMBDACDM constructed from galaxy
survey data to reproduce the large-scale structure and major objects
of the present-day Local Universe, CoDa II serves to model both global
and local reionization. In CoDa II, the Milky Way and M31 appear as
individual islands of reionization, i.e. they were not reionized by
the progenitor of the Virgo cluster, nor by nearby groups, nor by each
other.
Description: The galaxy catalogs for redshifts z=10 down to z=6 (the
simulation ended at z=5.8) are provided. Galaxies are identified as
Friends-of-Friends dark matter haloes with a linking length ll=0.2.
Stars are associated to each halo if they are within a sphere of
radius r200. Magnitudes are computed using a BPASS stellar population
model, as detailed in the article. No dust opacity is considered.
