3rd-order_statistics

comparing 3rd-order IA statistics from simulations and analytic models

goals

• 1. measure IA contribution to 3rd-order lensing staitsics in simulations
• 2. compare to theory predictions

simulations

• MICE:
  • light-cone, 1 octant, 0<z<1.2
  • including galaxies & lensing maps
  • intrinsic ellipticities from semi-analytic IA model
  • availalbe on cosmohub.pic.es

measurements

• 3pt shear correlations from tree-corr (Laila Linke, Sven Heydenreich, Lucas Secco)
• Bispectrum (Susan Pyne)

predictions

• "NLA" Bispectrum (Susan Pyne, Anik Halder, Laurence Gong)
• FT: Bispectrum -> 3PCF (Laila Linke, Sven Heydenreich)

milstones:

• 1. measure GGI terms in MICE
  • use LRGs in 5 spetroscopic redshift bins (0.0<z<1.0)
