* clusters/psformalism.py: Rewrite sample_z_m() methodAaron LI2017-10-042-38/+54
| | | | | Also update clusters/main.py to calculate the halo mass distributions before sampling the mass and redshifts for clusters.
* clusters: Use "hmf" to calculate halo mass functions/distributionsAaron LI2017-10-041-69/+136
| | | | | | | | | | | | * New dependency "hmf" (halo mass functions) module * Calculate halo mass distributions/functions (dndlnm) with respect to masses and redshifts, instead of use the previous data file ("ps_data") * New section "[extragalactic][psformalism]" in configurations * New functions to write and read the dndlnm data TODO: * update the method to sample (mass, redshift) for clusters from the dndlnm data
* clusters/psformalism.py: Improve catalog commentsAaron LI2017-10-021-4/+7

* clusters/emission: Assume electron pitch angle be pi/2Aaron LI2017-09-201-23/+17
| | | | And some cleanup and small changes
* clusters/emission: Rewrite synchrotron kernel functionAaron LI2017-09-201-9/+38
| | | | | | | | | | | Add asymptotic functions to calculate the values beyond the interpolation bounds (e.g., <1e-3 and >10), otherwise, the calculated synchrotron emissivity is overestimated at the higher frequencies. By rewrite this synchrotron kernel function, the calculated results is consistent with the theoretical/analytical results, e.g., the synchrotron radiation of a population of electrons of power-law index n is also a power-law with index (n-1)/2.
* clusters: Add option "use_output_catalog" to continue halo simulationAaron LI2017-09-031-4/+19
|
* clusters: Add config option "boost"Aaron LI2017-09-011-2/+5
| | | | | | | NOTE: The cluster number (especially the bright ones) may be rather small within a sky patch. This ``boost`` config option increase the expected cluster number by a specified times, for better testing purpose.

* clusters/emission.py: Make "F()" be class method, fixing memory hole!Aaron LI2017-08-011-22/+35
| | | | | | | | | | | For unknown reason! Each instance of "SynchrotronEmission" will cost ~5 MiB memory when interpolating the kernel function cached as "self._F_interp", which won't be collected/freed by GC, for UNKNOWN reason! Therefore, make the method "F()" be class-wide, to avoid the memory hole! Signed-off-by: Aaron LI <aly@aaronly.me>
