This page is meant to be a clearinghouse for requirements (desires?) for simulated maps and existing resources/capabilities for producing such maps

Created, 18Oct16

Wish List

  • Full-sky Healpix-pixelized maps at NSIDE=8192 (~0.4 arcmin resolution)
  • At least 8 frequency bands
  • Lensed CMB, Unlensed CMB, Kappa maps
  • Lots more...

Existing Resources / Capabilities

Nov 16 2016 CITA group (Dick, Marcelo, & George ) + Nick

We have developed a massively parallel LSS simulation pipeline for forecasting and application to upcoming experiments and surveys such as CMB-S4, DESI, and LSST.

The pipeline produces light cone halo catalogs and full-sky simulated observations suitable for data covariance determination by direct Monte Carlo, and includes beyond standard model (BSM) effects such as non-Gaussian initial conditions and evolving dark energy and undergoing continuous development for BSM effects.

+ Current data products and capabilities

++ 500 simulated full sky light cones (Healpix format)

++ Full sky maps:

  • Cluster/Group tSZ Effect (500 Compton y-maps)
  • Cluster/Group kSZ Effect (500 dT/T maps)

++ Can be simulated given specs (e.g. nu, flux cut, cosmo parameters):

  • Optical galaxy redshift catalogs for a given survey HOD
  • CIB maps at 100-2000 GHz for various models in literature
  • Light cones with specified resolution and survey geometries

+ Performance and computational resources

  • Full-sky catalogs take ~10 min each on 128 Scinet-GPC nodes, or ~20 node-hours
  • Full suite of 500 runs took ~1e4 node-hours, or ~2 days wall-clock
  • Map projection is a negligible fraction of computational cost

+ Models

  • The tSZ and kSZ maps use halo profiles obtained from hydrodynamical simulations ([[| BBPS 2012]] and [[| Battaglia 2016]])
  • So far the current CIB maps designed only for cross correlation work with clusters. The SED and profiles come from [[|Planck CIB model]]
  • The current optical HOD model is analogous to the one used for [[|BOSS mocks ]]
