* cosmology: Update virial overdensity calculationAaron LI2019-01-171-10/+16
| | | | | | References: * https://en.wikipedia.org/wiki/Virial_mass * http://adsabs.harvard.edu/abs/1998ApJ...495...80B
* clusters: Fix cluster distribution calculation about massAaron LI2018-05-121-3/+2
|
* utils/cosmology.py: Add parameter Tcmb0 [K]Aaron LI2017-10-041-4/+9
|
* utils/cosmology: Add scalar spectral index "ns"Aaron LI2017-10-041-4/+6
|
* utils/cosmology.py: Add methods Dc() and Dc_to_redshift()Aaron LI2017-10-021-0/+48
| | | | | | * Dc(): simple wrapper on astropy cosmology's comoving_distance() * Dc_to_redshift(): determine the redshift w.r.t. the input comoving distances using interpolation.
* clusters/psformalism: Remove config "f_darkmatter"Aaron LI2017-08-291-0/+10
| | | | Use "1 - baryon_fraction = 1 - Ob0/Om0" to replace "f_darkmatter".
