* | clusters/halo: Set fixed radius for RadioHaloAM | Aaron LI | 2018-12-23 | 1 | -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 LI | 2018-11-08 | 1 | -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. | |||||

| | | | | | | | 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 spectrum | Aaron LI | 2018-10-31 | 1 | -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. |
