## Period:
1 july - End of August (exact dates YTBD)
1 july - 24 August
## Meetings:
Meetings will be on monday and thursday 12 o clock.
Monday will be a bit more extensive.
Thursday will be just to make sure things are going smooth through the week.
## Week to week plan:
### week 1:
### Week 1 (1-7 July): Getting into the theory:
- [ ] Reading into Globular clusters and Open/Young clusters
- [ ] Reading into stellar evolution
- [ ] Get familiar in the group
- [ ] Look at python (see coding tab)
### week 2:
### Week 2 (8-14 July): continuing theory and doing some calculations:
- [ ] Get more into stellar evolution
- [ ] Read into stellar formation
- [ ] Get familiar with concepts like initial mass function, black hole formation
- [ ] Calculate 'goldilock zone' for cluster (calculating escape velocity based on cluster parameters to see which parameters allow for escaping of black holes)
- [ ] Calculate, using the IMF and a range of masses, how many black holes will form in a cluster of a given mass.
### week 3:
### Week 3 (15-21 July): Starting up some simulations:
- [ ] Using the results of last week, decide on initial conditions of the cluster that we will evolve.
- [ ] Read a bit about the N-Body6/7 code
- [ ] Set up some initial simulations and get the output
### week 4:
### Week 4 (22-28 July): Work on simulations and scripts to analyse:
- [ ] Do simulation of some clusters
- [ ] Start with analysing results of the first simulations
- [ ] Make some scripts to analyse the data, try to interpret it and understand it
### week 5:
### Week 5 (29 July - 4 Aug):
- [ ] Run some higher resolution simulations
- [ ] Possibly set up a very big simulation
- [ ] Analyse the results
### week 6:
### Week 6 (5-11 Aug): Play with extremes:
- [ ] Decide whether to do more simulations
- [ ] Modify some physics and try out some hacks (e.g. putting some initial black holes in the cluster)
### week 7:
### Week 7 (12-18 Aug): Wrapping up project:
This is coming to the end but its also quite far away, so the goals here are a bit general
- [ ] Analyse data from calculations
- [ ] Write up results and write up a form of report
The most important python packages in this case will be the following:
*`matplotlib` (For plotting)
*`numpy` (For numerical operations mostly)
*`scipy` (For statistical tools)
*`HDF5` (to read out the files)
*`pandas` (For data manipulation this tool is quite nifty)
* Common things like `sys`, `os`,
## Reading material:
### Introductionary reading material:
* https://www.ph.unimelb.edu.au/~mtrenti/Site/slides/StarClusters_Lecture1.pdf : Introductionary text on star clusters. Goes into the demography of clusters and their properties
* https://www.ast.cam.ac.uk/~vasily/Lectures/SDSG/sdsg_7_clusters.pdf : Same but a bit more indepth on globular clusters
* http://www.astro.caltech.edu/~george/ay20/eaa-globcl.pdf : Introduction on globular clusters from an observational point of view
* http://www.thijskouwenhoven.net/nbody.html : Website with lecutre notes on nbody simulations and the nbodyX software
* Reading material in materials/ dir
### In depth reading material
*[http://arxiv.org/abs/1902.07718](http://arxiv.org/abs/1902.07718): Paper on the implementation of new physics prescriptions into NBODY6. Shows some interesting results on BH retention
* https://www.sns.ias.edu/tremaine/lectures/ast513/globular : Overview of indepth papers on globular clusters
*[Website containing some lectures on N-body integration](http://silkroad.bao.ac.cn/web/index.php/seminars/lectures)
* https://arxiv.org/pdf/1708.09530.pdf : Nice paper on the initial mass function of stars in globular clusters, and how black hole retention plays a role in mass segregation
* https://arxiv.org/pdf/1712.03979.pdf : Paper on observational signatures of black hole populations in globular clusters
* https://arxiv.org/abs/1711.09100 : Quite a theoretical paper on the evolution of kicked black holes; what does the surrounding environment do to influence where they end up after a kick?
* http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?1991ARA%26A..29..543H&data_type=PDF_HIGH : observational paper on cluster properties: Catalogue of known clusters. This is a popular paper which contains a collection of the then known GCs in the local group.
* http://epubs.surrey.ac.uk/812065/1/MNRAS-2016-Peuten-2333-42.pdf : Paper which tries to determine whether a specific GC has a BH population, based on analyzed properties compared to nbody simulations
* https://arxiv.org/abs/1906.11855 : (!) Paper just released which contains part of our project goal. Quite an indepth paper which covers a lot of material that will be of interest to us.
### Other:
* http://adsabs.harvard.edu/abs/2013MNRAS.432.2779B : Paper where we got the inspiration for the project. Important paper for the general idea, but difficult in theoretical level
