CSiBORG Tools

Tools for analysing the suite of Constrained Simulations in BORG (CSiBORG) simulations. The interface is designed to work with the following suites of simulations: CSiBORG1 (dark matter-only RAMSES), CSiBORG2 (dark matter-only Gadget4), Quijote (dark-matter only Gadget2), however with little effort it can support other simulations as well.

Ongoing projects

Consistent halo reconstruction

  • Make a sketch of the overlap definition and add it to the paper.
  • Improve the storage system for overlaps and calculate it for all simulations.

Enviromental dependence of galaxy properties

  • Calculate the SPH density field for CSiBORG1.
  • Check that the velocity-field flipping of x and z coordinates is correct.
  • Evaluate and share the density field for SDSS & SDSSxALFALFA for both CSiBORG2 and random fields.
  • Check and verify the density field of galaxy colours (cannot do this now! Glamdring is super slow.)

Calculated data

SPH-density & velocity field:
  • CSiBORG2_main, CSiBORG2_random, CSiBORG2_varysmall
  • Evaluated for SDSS and SDSSxALFALFA in: CSiBORG2_main, CSiBORG2_random

Mass-assembly of massive clusters

  • Make a list of nearby most-massive clusters.
  • Write code to identify a counterpart of such clusters.
  • Write code to make a plot of mass-assembly of all clusters within a certain mass range from the random simulations.
  • Write code to compare mass-assembly of a specific cluster with respect to random ones.

Effect of small-scale noise

  • Study how the small-scale noise variation affects the overlap measure, halo concentration and spin.

Gravitational-wave and large-scale structure

  • Make the velocity field data available.

CSiBORG meets X-ray

  • Make available one example snapshot from the simulation. Mention the issue with x- and z-coordinates.

CSiBORG advertising

  • Decide on the webpage design and what to store there.
  • Write a short letter describing the simulations.
