* cosmology.py: Optimize the speed of overdensity_crit()Aaron LI2017-06-011-2/+11
|
* Update to use custom units.py instead of astropy'sAaron LI2017-06-013-52/+36
| | | | Also fix a parameter error in "formation.py"
* Add units.py: Commonly used units and conversions and constantsAaron LI2017-06-011-0/+66
| | | | | Astropy's unit conversions is too slow, thus store the used units conversions to avoid astropy's slow conversions.

| | | | | Adopt the finite difference scheme to solve the Fokker-Planck equation, following Park & Petrosian (1996, ApJS, 103, 255).
* Add clusters/mergertree.pyAaron LI2017-06-011-0/+77
| | | | | The merger tree is a binary tree that represents the merging (or formation) history of a cluster.

| | | | | | Mainly the "flat LambdaCDM" and "EdS" cosmological models. With some useful utility functions.

| | | | | * Update "output()" method to return the output file path * Update "simulate()" to also return the list of output file paths
* utils/__init__.py: Only import "setup_logging" from "logging.py"Aaron LI2016-10-291-1/+1
| | | | | | | | | | Since some modules (e.g., healpix.py) under "utils" involves Numba JIT optimization, which significantly slows the start-up speed, even some consumers (e.g., bin/fg21sim-webui) do not need them at all. Fix various import statements of other modules. NOTE: not test at the moment!

| | | | | | | | | Avoid using "astropy.units" in "calc_Tb()", which significantly speeds up this method. NOTE: whether the distance given by the simulation needs additional conversion to derive the *luminosity distance* ??

* Support new simulation component: extragalactic/clustersAaron LI2016-10-222-0/+654
Support simulate the radio emission from clusters of galaxies. Currently only the radio halos is considered, while the radio relics need more investigations. Also, this simulation requires a cluster catalog derived from the Hubble Volume Project simulation. NOTE: not tested at the moment
