* clusters/halo: Adopt new method for _velocity_turb()Aaron LI2018-11-081-15/+24
| | | | | | | | | | Adopt a new method to calculate the turbulence velocity dispersion. First, the kinetic energy released by the merger is estimated as the work done by the in-falling sub-cluster crossing the main cluster. Second, a fraction of the kinetic energy is assumed to be transferred into the turbulence. The turbulence mass is calculated as the gas mass enclosed within the turbulence region. Finally, the turbulence velocity dispersion is derived.
* clusters/halo: Add radius_stripping() methodAaron LI2018-11-081-3/+13
|
* clusters/halo: Apply option 'f_radius' to derive halo radiusAaron LI2018-11-082-6/+5
| | | | The config option 'f_radius' is renamed from the old 'f_lturb'.
* clusters/halo: New formula for radius_turbulence()Aaron LI2018-11-081-6/+12
| | | | | | | | Calculate the radius of the turbulence region as the mean of the stripping radius of the in-falling sub-cluster and the core radius of the main cluster. Also make the 't' parameter mandatory.
* clusters/halo: Add and use 'f_rc' and 'beta' optionsAaron LI2018-11-082-1/+11

|
* clusters/halo: Support to check whether halo is genuineAaron LI2018-11-012-0/+40
| | | | | | | Add the 'is_genuine()' method to check whether the radio halo is genuine by comparing the flux density to the fiducial value. Two new configuration options (fiducial_freq and fiducial_factor) are added to specify the frequency and limit whether the radio halo is regarded as genuine.

* clusters/halo: Support to calculate the fiducial electron spectrumAaron LI2018-10-311-7/+20
| | | | | | | The fiducial electron spectrum is the one that is derived with the turbulent acceleration turned off. It can be used to determine whether the acceleration is indeed effective for one cluster and then further determine whether the radio halo is formed/observable.
* clusters/halo: Simplify calc_electron_spectrum()Aaron LI2018-10-311-49/+6
| | | | | | | | Get rid of the 'electron_spec' property and the set_electron_spectrum() function. Simplify the calc_electron_spectrum() by removing the step adjustment. Other minor cleanups.
* clusters/halo: Rework the way to disable turbulent accelerationAaron LI2018-10-311-16/+13
| | | | | | Introduce a new property '_acceleration_disabled' to control whether the turbulent acceleration is disabled. With this new property, improve the code to derive the initial electron spectrum.
* clusters/halo: Use _is_turb_active() in fp_advection()Aaron LI2018-10-311-14/+6
| | | | Some other minor cleanups.

* clusters/halo: Update turbulence velocity calculationAaron LI2018-10-301-26/+40
| | | | | | | | Adopt the same beta-model for the gas density profile to calculate the gas/baryon mass within the turbulence region (<R_turb). Meanwhile, change the '_velocity_turb()` method to a property without depending on the time, to further simplify the model a bit.
