* clusters: Assume equipartition between B field and CRAaron LI2019-01-253-16/+18
| | | | | | Equipartition between the magnetic fields and cosmic rays is assumed, i.e., eta_b == x_cr. Therefore remove "extragalactic/clusters/eta_b" configuration option.

* 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.
