* clusters/emission: Add calc_emissivity_bolo()Aaron LI2019-01-271-6/+33
|
* clusters/emission: improve description symbols :-)Aaron LI2018-01-211-4/+4
|
* clusters/halo: split emissivity/power/flux calculations into HaloEmissionAaron LI2018-01-031-1/+200
| | | | | Add emission.HaloEmission class to calculate halo emissivity, power, flux, brightness etc.
* clusters/emission: minor cleanupsAaron LI2018-01-021-14/+6
|
* clusters/halo: Use "lru_cache()", also improves some performanceAaron LI2017-10-231-0/+3
|
* clusters/emission: Assume electron pitch angle be pi/2Aaron LI2017-09-201-23/+17
| | | | And some cleanup and small changes
* clusters/emission: Rewrite synchrotron kernel functionAaron LI2017-09-201-9/+38
| | | | | | | | | | | Add asymptotic functions to calculate the values beyond the interpolation bounds (e.g., <1e-3 and >10), otherwise, the calculated synchrotron emissivity is overestimated at the higher frequencies. By rewrite this synchrotron kernel function, the calculated results is consistent with the theoretical/analytical results, e.g., the synchrotron radiation of a population of electrons of power-law index n is also a power-law with index (n-1)/2.
* clusters/emission.py: Make "F()" be class method, fixing memory hole!Aaron LI2017-08-011-22/+35
| | | | | | | | | | | For unknown reason! Each instance of "SynchrotronEmission" will cost ~5 MiB memory when interpolating the kernel function cached as "self._F_interp", which won't be collected/freed by GC, for UNKNOWN reason! Therefore, make the method "F()" be class-wide, to avoid the memory hole! Signed-off-by: Aaron LI <aly@aaronly.me>
* clusters/emission.py: Fix bug in "F()"Aaron LI2017-08-011-13/+14

* clusters/emission.py: Remove methods and clean up parametersAaron LI2017-07-291-78/+2
| | | | | | | | * Methods "power()", "flux()" already moved to "halo.py"; * Method "brightness()" will also be moved over there; * Clean up thus unused parameters "z" and "radius", as well as imports. Signed-off-by: Aaron LI <aly@aaronly.me>
* clusters/emission.py: support calc emissivity at multiple frequenciesAaron LI2017-07-291-17/+27

* 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``)!

* 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>

* clusters/emission.py: Rewrite Synchrotron kernel function calculationAaron LI2017-07-261-3/+41
| | | | | | | Use interpolation to optimize the speed as well as to vectorize the function to ease calling. Signed-off-by: Aaron LI <aly@aaronly.me>
