* clusters/halo: adjust radio halo size estimationAaron LI2018-01-011-3/+3
|
* clusters/halo: improve turbulence velocity dispersion calculationAaron LI2018-01-011-9/+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" attributeAaron LI2017-12-312-4/+15
|
* clusters/halo: Rework the turbulence acceleration timescale calculationAaron LI2017-12-311-47/+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: Rewrite turbulence acceleration & diffusion coefficient!Aaron LI2017-10-212-58/+92
| | | | | | | | | | | | The previous calculation of the turbulence acceleration efficiency has significant problems, which is too low, i.e., the acceleration timescale is too large (~10 Gyr). However, it is reported that turbulent acceleration has a timescale ~100 Myr (0.1 Gyr). I believe this problem is due to the over-simplification to the formula proposed by [cassano2005]. Rewrite the turbulence acceleration and diffusion coefficient calculations, adopting the method proposed by [brunetti2016]. To this end, two new options "f_lturb" and "f_acc" are introduced to tune the results.
