OU-LE3 simulation needs

  • Returns from
  • Clusters of galaxies - implementation
  • A. Biviano, S. Maurogordato, C. Benoist, S. Borgani, G.

De Lucia.

  • Time domain

SLIDE 4

Generic needs

  • Simulated photo-z catalogue
slide-5
SLIDE 5

Specific needs – clusters of galaxies

  • DM haloes M>1.e+13Msun, r(D), D=2500,

500,200; velocity dispersion along axes from DM particles

  • For each galaxy host halo ID, central or sat?
  • Simulated images for cluster detection and

mass determination through weak/strong lensing

  • Do need require full instrumental response at

this stage

slide-6
SLIDE 6

Specific needs: weak lensing

  • Galaxies and DM to generate kappa map
  • Galaxy shapes with noise (no IA)
  • Galaxy shapes with IA
  • Shear at each galaxy position
  • Image properties:

mask, bright stars, chip boundaries, CCD defects, ghosts, variations in depth & background

slide-7
SLIDE 7

Specific needs: Time Domain

  • Science areas: SNe, exo-planets, solar system
  • Time series of VIS and NISP Y, J, H images
  • Add fake transients with realistic properties

(lightcurves, colours, positions) – properties to be supplied by Time Domain scientists

  • Images should be pre-processed (bias corrected,

flat fielded and sky subtracted). Individual dithered frames should be available so that an

  • versampled reference image can be constructed.
slide-8
SLIDE 8

Specific needs: time domain

Images should tile the following areas

  • a few arcmin in a crowded stellar field

(exoplanets case)

  • ~1 sq deg in a high galactic latitude field (for

the SN case).

  • ~100 sq deg covering the range of stellar

densities and galaxy cluster backgrounds that are expected (for the solar system case)

slide-9
SLIDE 9

Specific needs: time domain

  • Simulated NISP spectroscopy of a subset of

the areas above

  • both time-resolved and stacked images.

Spectroscopic properties of the target objects will be provided by the OULE3 Time domain WP scientists.
