CSiBORG tools

CSiBORG Matching

TODO

  • Implement CIC binning or an alternative scheme for nearby objects.
  • Consistently locate region spanned by a single halo.
  • Write a script to perform the matching on a node.
  • Make a coarser grid for halos outside of the well resolved region.

Questions

  • What scaling of the search region? No reason for it to be a multiple of R_{200c}.
  • How well can observed clusters be matched to CSiBORG? Do their masses agree?
  • Is the number of clusters in CSiBORG consistent?

CSiBORG Galaxy Environmental Dependence

TODO

  • Add gradient and Hessian of the overdensity field.
  • Write a script to smoothen an overdensity field, calculate the derived fields and evaluate them at the galaxy positions.

Questions

  • Environmental dependence of:

    • M_*, colour and SFR.
    • Galaxy alignment.
    • HI content.

  • Fields to calculate:

    1. Overdensity field \delta
    2. Gradient and Hessian of \delta
    3. Gravitational field \Phi
    4. Gradient and Hessian of \Phi
