* clusters/halo: Increase the time step, but require a minimum of 20 stepsAaron LI2017-10-181-0/+7
|
* clusters: Update radio halo radius estimationAaron LI2017-10-181-4/+8
| | | | | | | | | 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].
* clusters: Update the documents/comments a b itAaron LI2017-10-141-2/+2
|
* clusters/halo.py: Update injection rate calculationAaron LI2017-08-261-10/+5

* clusters/halo.py: Add method "calc_emissivity()"Aaron LI2017-07-291-6/+37

* clusters/halo: Change config "eta_turb" to "beta_turb"Aaron LI2017-07-251-3/+3
| | | | | | | | | | This configuration option "beta_turb" has different meaning as "eta_turb" in [Cassano & Brunetti 2005], though they can both be an indicator for the turbulence acceleration efficiency. Rename this configuration option to make the difference more clear. Signed-off-by: Aaron LI <aly@aaronly.me>

| | | | | | | | | | Zero or negative diffusion coefficient leads to unstable or wrong results due to numerical algorithm/scheme adopted to solve the Fokker-Planck equation. Also add a NOTE to the FokkerPlanckSolver class. Signed-off-by: Aaron LI <aly@aaronly.me>
