| | | | | | | Calculate the synchrotron power (a.k.a. specific luminosity) and flux density from the emissivity for the halo. Signed-off-by: Aaron LI <aly@aaronly.me>
* clusters/halo.py: Add method "calc_emissivity()"Aaron LI2017-07-291-6/+37
| | | | | | | This method invokes ``SynchrotronEmission`` to calculate the synchrotron emissivity at specified frequencies for the derived electron spectrum. Signed-off-by: Aaron LI <aly@aaronly.me>

* clusters/emission.py: Fix units/dimensions problemAaron LI2017-07-261-1/+2
| | | | | | | | | | | NOTE: Since we just substitute ``p`` (electron momentum) for ``γ`` (electron Lorentz factor), i.e., N = int_p n(p) dp = int_γ n(γ) dγ , therefore the coefficient ``sqrt(3) e^3 B / (m c^2)`` does NOT need modification (e.g., multiply an extra ``m c``)! Signed-off-by: Aaron LI <aly@aaronly.me>

* clusters/emission.py: Rewrite emissivity calculationAaron LI2017-07-261-15/+24
| | | | | | | | | | Use 2D grid of (discrete) samples to optimize integration speed, avoiding the more complicated integration w.r.t. functions. WARNING: Current calculation results seems wrong! Signed-off-by: Aaron LI <aly@aaronly.me>

| | | | Signed-off-by: Aaron LI <aly@aaronly.me>

* clusters/halo: Change config "eta_turb" to "beta_turb"Aaron LI2017-07-252-6/+5
| | | | | | | | | | This configuration option "beta_turb" has different meaning as "eta_turb" in [Cassano & Brunetti 2005], though they can both be an indicator for the turbulence acceleration efficiency. Rename this configuration option to make the difference more clear. Signed-off-by: Aaron LI <aly@aaronly.me>

* clusters/halo.py: Constrain tau_acc to avoid zero diffusionAaron LI2017-07-232-2/+22
| | | | | | | | | | Zero or negative diffusion coefficient leads to unstable or wrong results due to numerical algorithm/scheme adopted to solve the Fokker-Planck equation. Also add a NOTE to the FokkerPlanckSolver class. Signed-off-by: Aaron LI <aly@aaronly.me>
