* | clusters/halo: Apply option 'f_radius' to derive halo radius | Aaron LI | 2018-11-08 | 1 | -2/+2 |
| | | | | The config option 'f_radius' is renamed from the old 'f_lturb'. | ||||
* | clusters/halo: New formula for radius_turbulence() | Aaron LI | 2018-11-08 | 1 | -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' options | Aaron LI | 2018-11-08 | 1 | -1/+4 |

* | clusters/halo: Support to check whether halo is genuine | Aaron LI | 2018-11-01 | 1 | -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. | ||||
* | clusters/halo: Fix the 'lru_cache' usage | Aaron LI | 2018-10-31 | 1 | -2/+2 |

* | 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. | ||||
* | clusters/halo: Simplify calc_electron_spectrum() | Aaron LI | 2018-10-31 | 1 | -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 acceleration | Aaron LI | 2018-10-31 | 1 | -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 LI | 2018-10-31 | 1 | -14/+6 |
| | | | | Some other minor cleanups. | ||||

* | clusters/halo: Update turbulence velocity calculation | Aaron LI | 2018-10-30 | 1 | -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. | ||||

| | | | | | Change "tau_acceleration" from a attribute to a method with the time parameter, and then simplify "fp_diffusion()" method. | ||||
* | clusters/halo: Add preliminary RadioHaloAM based on RadioHalo | Aaron LI | 2018-01-04 | 1 | -0/+103 |
| | | | | | The RadioHaloAM class is intended to account for all merger events, and there are a lot of methods to be implemented. | ||||

| | |||||
* | clusters/halo: improve turbulence velocity dispersion calculation | Aaron LI | 2018-01-01 | 1 | -9/+9 |
| | | | | | | | Use the merged total mass instead of the main cluster mass only as the denominator to determine the turbulence velocity dispersion, which reduces the scatter and thus the acceleration results will be less sensitive to the (mostly unknown) merging turbulence properties. | ||||
* | clusters/halo: Add back "mach_turbulence" attribute | Aaron LI | 2017-12-31 | 1 | -3/+14 |
| | |||||
* | clusters/halo: Rework the turbulence acceleration timescale calculation | Aaron LI | 2017-12-31 | 1 | -47/+39 |
| | | | | | | | | The new method adopted to determine the turbulence acceleration timescale follows [miniati2015] and [pinzke2017], in which the merger-induced turbulence cascades into small scales (and thus accelerate electrons) through the TTD (transit-time damping) mechanism by scattering mainly with the relativistic particles (cosmic-ray protons and electrons). | ||||
* | clusters/halo: calc turbulence velocity dispersion based on merger | Aaron LI | 2017-12-31 | 1 | -0/+38 |
| | | | | | Also update the description of option "extragalactic/halos/eta_turb" and change its default value to 0.1 | ||||
