Comments |
src.sigma8 |
initial spectrum normalization parameter |
|
|
src.omega.stellar |
stellar content density parameter |
|
just a few examples of omegas (add all the others you need) |
src.omega.radiation |
radiation related density parameter |
|
just a few examples of omegas (add all the others you need) |
src.omega.matter |
matter density parameter |
|
just a few examples of omegas (add all the others you need) |
src.omega.lambda |
cosmological constant related density parameter |
|
just a few examples of omegas (add all the others you need) |
src.omega.baryon |
baryon content density parameter |
|
just a few examples of omegas (add all the others you need) |
src.omega |
density parameters of the universe |
to be used as root for all omegas used or alone to indicate the the global density parameter |
|
src.hubble0 |
Hubble constant, H0, equals the Hubble parameter at z=0 |
|
These 2 UCDs can maybe be simplified into one |
src.hubble |
hubble paramater, H |
|
These 2 UCDs can maybe be simplified into one |
src.cosmologicalmodel? |
cosmological model used |
Lambda Cold Dark Matter, other |
|
src.boxsize |
linear dimension of the cosmological box simultaed |
|
|
phys.temperature.speclike |
spectrum-like temperature |
|
|
phys.temperature.massweighted |
mass-weighted temperature |
|
|
phys.temperature.emissionweighted |
emission-weighted temperature |
|
|
phys.radius.rhocritic.NNN |
NNN times the rhocritic-radius |
extensions to the critical radius concept, with NNN usually 200, 500, 2500 |
Another way to define such relations could be use a src.rhocritic word and then the compounds like phys.radius;src.rhocritic. This ucd can also be used to specify where some quantities are evaluated, i.e. phys.temperature.speclike;phys.radius.rhocritic |
phys.radius.rhocritic |
radius (of an object, say a cluster of galaxies) where the density equals the critical density of the universe |
the critical density is used as a comparing term to other densities, also used as a reference for the above mentioned density parameters. Usually one describes radial distances inside clusters, for example, as N times the radius where the density equals the critical density |

??? |
gas or gas related |
propose a way to define objects interesting in simulation but not only in simulations, like gas, stars, galaxies. These UCDs can be useful as S words to specify to what the quantities are referred to, i.e. phys.mass of what? a star? the halo of a galaxy? |
maybe using object.gas? |
??? |
dark matter related |
propose a way to define objects interesting in simulation but not only in simulations, like gas, stars, galaxies. These UCDs can be useful as S words to specify to what the quantities are referred to, i.e. phys.mass of what? a star? the halo of a galaxy? |
object.dm? |
??? |
stars or stellar objects related |
propose a way to define objects interesting in simulation but not only in simulations, like gas, stars, galaxies. These UCDs can be useful as S words to specify to what the quantities are referred to, i.e. phys.mass of what? a star? the halo of a galaxy? |
object.stellar? |
??? |
code used for the simulation |
|
