## CSiBORG Matching
|
|
|
|
### TODO
|
|
- [x] Implement CIC binning or an alternative scheme for nearby objects.
|
|
- [x] Consistently locate region spanned by a single halo.
|
|
- [x] Write a script to perform the matching on a node.
|
|
- [x] 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.
|
|
- [x] 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 $\Phi$
