Data

Raw data consists in snapshots, samples and lightcones. After post-processing, three kinds of data have been produced: cubes or fields (particles sorted per region), halos (particles sorted on a per halo basis) and lightcones (particles on the lightcone sorted per redshift). For a discussion on the file format see Documentation Page on database DEUVO, here, we described the main characteristics.

Fields

What is it ? Particles sorted per region
What are the particles properties ? Position (distribution), velocity (kinematics), identity (follow particles from one snapshot to another)
What are the redshifts available ? More than 10 per simulations: a=astart,0.025,0.05,0.1,0.15…,0.95,1
What are the scales probed ? From 3. kpc to 10. Gpc
What could I do with it ? Any field oriented analysis: correlation, distribution, filament, weak lensing, BAO…

 

Halos

What is it ? Particles sorted on a per halo basis
What are the particles properties ? Position, velocity, identity ….
What are the redshifts available ? More than 10 per simulations: a=astart,0.025,0.05,0.1,0.15…,0.95,1
What are the halos probed ? From 2.5 .10^10 to 1. 10^16 Msun, from 100 to 3 millions particles.
What could I do with it ?Any halo oriented analysis: cluster counts, strong lensing, statistics on macroscopic properties and internal profiles…

Lightcones


What is it ? Particles on the lightcone (ie as we see them and not at a given instant). Particles are dumped at each coarse time step in RAMSES_DEUS, and then sorted per redshift during the post-processing.
What are the particles properties ? Position, velocity, redshift
What are the opening angle and depth available ? 6 narrow lightcones: 20×20 degres^2 up to z=6 and 3 full sky lightcones up to z=1.
What could I do with it ? Any observation oriented study: weak lensing, cluster counts…
