* clusters/halo: Update the estimation of radius_turbulence()Aaron LI2019-01-171-4/+8
| | | | | The radius_turbulence is estimated as the stripping radius (r_s) if r_s is larger than the core radius (r_c) of the main cluster, otherwise, r_c.

|
* clusters/halo: Set fixed radius for RadioHaloAMAaron LI2018-12-231-2/+14
| | | | | | | Since the halo radius is related to the turbulence injection region size which is further related to the stripping radius, it varies along the cluster growth as mergers happen. Therefore, the finally radio halo radius is determined otherwise and just specified here.

|
* 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.

| | | | | | | | 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: Support to check whether halo is genuineAaron LI2018-11-011-0/+33
| | | | | | | 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.

|
* PEP8 fixAaron LI2018-10-311-2/+2
|
* 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: 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.

|
* clusters/help: Add radius_stripping()Aaron LI2018-10-261-6/+73
| | | | | This function calculates the stripping radius of the sub-cluster when it falling through the main cluster.
