SIMULATION HELPER
From this web page various simulations for present and future surveys can be accessed.
Galaxy source count data, survey predictions and Number redshift distributions can be obtained.
The simulations are based on the models of Pearson C.P., 2001, MNRAS, 325, 1511.
All models are based on a 4 component infra-red galaxy evolution model consisting of
Pure luminosity evolution is assumed for the Starburst, AGN components while a combination of luminosity and density evolution is assumed for the ULIG component. The counts provide an excellent fit to the source counts and extragalactiv background radiation from radio to NIR wavelengths. See this URL for more information.
Using the Galaxy Counts pull down menu, galaxy source counts can be obtained over a wide range of wavelengths from sub-mm to near-IR.
Using the Numbers pull down menu, the predictions for a wide range of past, present and future missions are tabulated in HTML tables.
Using the Nz pull down menu, the corresponding Galaxy Number-Redshift distributions can be downloaded
Explanations can be specicically accessed from the HELP pull down menu or simply continue to scroll down to the next section here.
Please feel free to link to this site. For further comments, suggestions or requests please contact me.
Selecting the Galaxy Counts pull down menu opens a list of wavelengths. selecting a waveband opens the folder to the integral source count files.
The files contain the integral counts files contain counts for all model components given as lg(flux) in Jy and lg(number) per SQUARE DEGREE.
The filename format is :-
RES-count-band-component
therefore :-
** RES60CIRR.DAT ** are the integral counts per square degree at 60um for the normal galaxy model component.
** RES9.DAT ** are the TOTAL (since no component is stated) integral counts per sq.deg. at 9um.
Selecting the Numbers pull down menu opens a list of missions. Selecting a mission open a set of tables containing
For all individual galaxy components.
If further information is required, please contact me
Selecting the Nz pull down menu opens a list of missions. Selecting a mission opens the folder containing the Number-Redshift Distribution simulations for that particular mission / survey.
The Nz directories are labelled by wavelength, galaxy component and assumed sensitivity (in mJy)
The Nz directories contain the number of sources (dN over an interval dz=0.1) for the survey area as a function of redshift. The file format is redshift - lg(dN), assuming a redshift bin of 0.1.
The filename format is :-
NZ-band-component-sensitivity(mJy)
therefore :-
** NZ170AGN55.DAT ** are the Number Redshift Distributions at 170um for the AGN model component at a flux limit of 55mJy.
** NZwide20TOT100.DAT ** is the TOTAL Number Redshift Distribution for all components at 20um at a flux limit of 100mJy.
Note that these results are currently available for a Ho=72, omega=0.3, lambda=0.7 cosmology.
