|
* clusters/halo: Add method to derive the initial electron spectrumAaron LI2017-10-251-0/+5
| | | | | Also add the option "time_init" to control how long a period is used to derive the initial electron spectrum.

* clusters/halo: Rewrite turbulence acceleration & diffusion coefficient!Aaron LI2017-10-211-2/+12
| | | | | | | | | | | | The previous calculation of the turbulence acceleration efficiency has significant problems, which is too low, i.e., the acceleration timescale is too large (~10 Gyr). However, it is reported that turbulent acceleration has a timescale ~100 Myr (0.1 Gyr). I believe this problem is due to the over-simplification to the formula proposed by [cassano2005]. Rewrite the turbulence acceleration and diffusion coefficient calculations, adopting the method proposed by [brunetti2016]. To this end, two new options "f_lturb" and "f_acc" are introduced to tune the results.
* clusters/halo: Determine magnetic field by fraction of its energy densityAaron LI2017-10-201-8/+4
| | | | | | | | | | * Rewrite "magnetic_field()" function to calculate the mean magnetic field strength within ICM according its energy density fraction w.r.t. the ICM thermal energy density. * Remove config options "b_mean" and "b_index", which are replaced with the option "eta_b", the assumed magnetic energy density fraction w.r.t. the ICM thermal energy density.
* clusters: Update configuration defaults and descriptionAaron LI2017-10-191-12/+12
|
* clusters/halo: Support use the previously dumped halos raw dataAaron LI2017-10-192-0/+15
| | | | | | Add option "use_dump_halos_data" to control whether to just use the previously dumped halos data, therefore, the radio emissions at additional frequencies can be simply calculated.
* clusters/halo: Rewrite halos catalog and raw data saveAaron LI2017-10-191-3/+11
| | | | | Replace option "halos_dumpfile" with "halos_catalog_outfile", and use option "dump_halos_data" to control whether to dump the raw data.
* clusters: "catalog_outfile" is requiredAaron LI2017-10-191-0/+2
|
* clusters/halo: Increase the time step, but require a minimum of 20 stepsAaron LI2017-10-181-1/+1

|
* clusters: Use "hmf" to calculate halo mass functions/distributionsAaron LI2017-10-042-13/+46
| | | | | | | | | | | | * 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

|
* configs: Update option descriptions; also tweak checkers a bitAaron LI2017-09-032-7/+12
|
* clusters: Add config option "boost"Aaron LI2017-09-011-0/+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.
* configs/logging: print time only, without dateAaron LI2017-09-011-1/+1
|
* configs: Update clusters simulation parametersAaron LI2017-08-311-4/+4
| | | | | | | Carried many simulation tests to determine the best parameters, by comparing with the integrated counts distribution (i.e., halo luminosity function) reported in previous works (Cassano2006, Cassano2012, and Ensslin2002).
* clusters/psformalism: Remove config "f_darkmatter"Aaron LI2017-08-291-3/+0
