Full-sky Gravitational Lensing Mock
Catalogs Japanese
language
We
provide full-sky lensing mock catalogs based on a multiple-lens ray-tracing
scheme through cosmological N-body simulation (Takahashi, Hamana,
Shirasaki+ 2017). Here are three kinds of catalogs: weak lensing maps
(convergence, shear and rotation data), CMB lensing maps (temperature and
polarization data), and halo catalogs（halo
masses, angular positions, redshift data and so on）. We used three public codes in the simulation: the cosmological
N-body code Gadget2 (Springel
2005), the ray-tracing code GRaytrix (Hamana+ 2015, Shirasaki+ 2015), and
the halo finder Rockstar (Behroozi+ 2013). The pixelization of full-sky maps follows the Healpix ring scheme (Gorski+ 2005). The weak
lensing maps are presented at every 150Mpc/h (comoving
distance) from redshift z=0.05 to 5.3, and at z=1100 for the CMB lensing. We
adopted the cosmological parameters consistent with the WMAP 9 year result （Omega_m=1-Omega_Lambda=0.279, Omega_cdm=0.233,
Omega_b=0.046, h=0.7, sigma_8=0.82, and ns=0.97）. The linear matter power spectrum at z=0 is here. Please read our paper for further
information about the simulation.
The angular resolutions are specified by
the Healpix parameter Nside=4096,
8192, and 16384 which correspond to pixel angular sizes of 0.86, 0.43 and 0.21 arcmin, respectively. There are 108 realizations each for Nside=4096 and 8192, and a single realization for Nside=16384, which are altogether labeled r000 to r107. As
the maps with the same label but different Nside
derive from the same N-body data, they represent the same mass distribution but
simply differ in terms of angular resolutions. You can download the catalogs
