The AST9240 -- Cosmology II course assignment(s).

AST9240 -- Cosmology II

The repo contains code(s) created based on the Fortran templates provided for AST9240 -- Cosmology II course from University of Oslo. It consists of 4 projects in total:

1. The background evolution of the Universe
2. The recombination history of the Universe
3. The evolution of structures in the Universe
4. The CMB power spectrum

Reports for all 4 parts located in reports folder within this repo.

The assignments and some materials can be found inside materials folder within this repo.

The total list of materials for the course can be found on official course page here: https://www.uio.no/studier/emner/matnat/astro/AST5220/v19/pensumliste/index.html

Prerequisites

To install the code you need to have the following libraries preinstalled first:

1. CFitsIO;
2. HEALPix;
3. BLAS/LAPACK;

You will also need to have a Fortran compiler. The primary compiler used was from Intel, but GNU GFortran should also work, given the correct compiler flags.

Once you installed all prerequisites, modify Makefile to incorporate the changes.

Compile

To compile the project simply type:

$ make

in the root. This will produce executable called cmbspec.

Note: I have modified the original template Makefile to split src codes from compiled mod and obj files. This means that you will need to create new directory inside root called obj for make to work.

Run

To run the code type:

$ ./cmbspec

It will start all necessary processing. The resulting files will be stored inside data folder within root.

To plot the results for each subproject, use ipynb contained within this repo.

Note: you need to create data directory before you started processing otherwise it will not work.
