# 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 simulations (full support),
|
||||
- CSiBORG2 dark matter-only Gadget4 simulations (planned full support),
|
||||
- Quijote dark matter-only Gadget2 simulations (partial support),
|
||||
however with little effort it can support other simulations as well.
|
||||
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.
|
||||
- [x] 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*
|
||||
|
||||
|
||||
## TODO
|
||||
- [x] Prune old CSiBORG1 merger tree things.
|
||||
- [x] Add visualiastion of the density field.
|
||||
- [ ] Clear out `density` support.
|
||||
- [ ] Add sorting of Gadget4 initial snapshot like final snapshot.
|
||||
- [ ] Add full support for CSiBORG2 suite of simulations.
|
||||
- [ ] Add SPH field calculation from cosmotools.
|
||||
### 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.
|
||||
|
||||
|
||||
## Adding a new simulation suite
|
||||
### Effect of small-scale noise
|
||||
- [ ] Study how the small-scale noise variation affects the overlap measure, halo concentration and spin.
|
||||
|
||||
box units
|
||||
paths
|
||||
readsim
|
||||
halo_cat
|
||||
### 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.
