Abstract:
We present a new cosmological galaxy formation model, nu2GC, as an
updated version of our previous model nuGC. We adopt the so-called
"semi-analytic" approach, in which the formation history of dark
matter halos is computed by N-body simulations, while the baryon
physics such as gas cooling, star formation, and supernova feedback
are simply modeled by phenomenological equations. Major updates of the
model are as follows: (1) the merger trees of dark matter halos are
constructed in state-of-the-art N-body simulations, (2) we introduce
the formation and evolution process of supermassive black holes and
the suppression of gas cooling due to active galactic nucleus (AGN)
activity, (3) we include heating of the intergalactic gas by the
cosmic UV background, and (4) we tune some free parameters related to
the astrophysical processes using a Markov chain Monte Carlo method.
Our N-body simulations of dark matter halos have unprecedented box
size and mass resolution (the largest simulation contains 550 billion
particles in a 1.12Gpc*h-1*box), enabling the study of much smaller
and rarer objects. The model was tuned to fit the luminosity functions
of local galaxies and mass function of neutral hydrogen. Local
observations, such as the Tully-Fisher relation, the size-magnitude
relation of spiral galaxies, and the scaling relation between the
bulge mass and black hole mass were well reproduced by the model.
Moreover, the model also reproduced well the cosmic star formation
history and redshift evolution of rest-frame K-band luminosity
functions. The numerical catalog of the simulated galaxies and AGNs is
publicly available on the web.
Description:
The mock galaxy catalog calculated by the nu2-GC model described in
the paper.
File light-cone_nu2gc-H2.dat contains the galaxies having B-band
apparent magnitude brighter than 28 [AB mag] and located at the
redshift range 0<z<20.0, with 1 deg2 aperture.
We also provide "box-type" mock galaxy catalogs,
catalognu2gc-Lz**.dat, that contain the simulated galaxies in the
1.123 (Gpc/h)3 size box at redshift z = 0.0, 0.48, 1.01, 1.97, 2.95,
6.97. For each simulated galaxy, redshift, comoving distance, stellar
mass, gas mass, black hole mass, star formation rate, metallicity, and
magnitude in B-, V-, SDSS-rp and 2MASS-Ks bands are given.
Terms of Use :
When you write papers using these catalogs, we would be very grateful
if you could refer the following two papers: Ishiyama et al.,
2015PASJ...67...61I 2015PASJ...67...61I, Makiya et al., 2016PASJ...68...25M 2016PASJ...68...25M.
Description of files:
The catalogs are generated by the nu2GC-L model.
Chabrier IMF (0.1-100M☉) is assumed.
Stellar population synthesis model provided by Bruzual and Charlot
(2003MNRAS.344.1000B 2003MNRAS.344.1000B) 1000 is used to calculate a luminosity of galaxies.
nu2GC simulations
We use state-of-art cosmological N-body simulations
conducted by using a massively parallel TreePM code GreeM.
For available mock catalogues, we employ
-- nu2GC-L simulation (GEOMETRY):
-- Box size: 1120 [h^-1 Mpc]
-- Number of particle: 8192^3
-- particle mass resolution: 2.28e+8 [h^-1 Msun]
-- minimum halo mass: 8.79e+9 [h^-1 Msun]
and
- nu2GC-H1 simulation (LIGHT-CONE):
-- Box size: 140 [h-1Mpc]
-- Number of particle: 20483
-- particle mass resolution: 2.75e+7 [h-1Msun]
-- minimum halo mass: 1.10e+9 [h-1Msun].
