|
* clusters/halo: Estimate turbulence acceleration w.r.t. injection scaleAaron LI2017-12-301-0/+23
| | | | The turbulence injection scale ~ halo size
* cluster/halo: Estimate halo radius ~ 0.33*R_vir (main cluster)Aaron LI2017-12-301-7/+16
|
* clusters/halo: Fix passing the "configs" objectAaron LI2017-10-251-1/+1
|
* clusters/halo: Always pass the using configsAaron LI2017-10-241-6/+6
| | | | | The user-using `configs` object may be different to the global `CONFIGS`, which may be forgotten to load the up-to-date user configurations.
* clusters/halos: Fix halo radius calculationAaron LI2017-10-231-3/+5
| | | | Also change the parameter "nr" default to 2.0 for draw_halo() function.
* clusters/halo: merge halo_rprofile() & draw_halo(); Fix halo radius errorAaron LI2017-10-231-38/+26
| | | | | | | * Fix the error that misses to divide the halo radius by 3 for the e-folding radius, which causes the generated halo image has a 3x size! * Merge function "halo_rprofile()" into "draw_halo()" * Skip transform circular halo into elliptical one if "felong" is None
* clusters/halo: Use "lru_cache()", also improves some performanceAaron LI2017-10-231-1/+1
|
* clusters/halo: Add option "kT_out" to tune cluster temperatureAaron LI2017-10-221-2/+6
|
* clusters/halo: Add function "speed_sound()"Aaron LI2017-10-211-0/+28
| | | | Also add "gamma" the adiabatic index of ideal gas to utils/units.py
* clusters/halo: Determine magnetic field by fraction of its energy densityAaron LI2017-10-201-30/+24
| | | | | | | | | | * 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/halo: Remove "mass_to_kT()", replaced by "kT_cluster()"Aaron LI2017-10-201-39/+0
|
* clusters/halo: Use "kT_cluster()" instead of "mass_to_kT()"Aaron LI2017-10-191-3/+3
|
* clusters/halo: Add kT_cluster() to calculate the cluster ICM temperatureAaron LI2017-10-191-0/+25
|
* clusters/helper: Add kT_virial() to calculate the virial temperatureAaron LI2017-10-191-0/+36
|
* clusters/halo: rewrite power/flux/Tb calc with k-correction consideredAaron LI2017-10-191-102/+0
|
* clusters: Update radio halo radius estimationAaron LI2017-10-181-19/+17
| | | | | | | | | The simulated radio halo is assumed to have a radius of the falling sub-cluster; while previously it is assumed to be 1/4 of the virial radius of the merged cluster. The new estimation can agree better with the currently observed radio halos, which generally have a angular diameter size of ~2-7 [arcmin].
* Update "Fnu_to_Tb_fast()" to "Fnu_to_Tb()"Aaron LI2017-09-011-2/+2
