DESCRIPTION:Measurements of the clustering of large scale structure can pl
 ace strong constraints on our understanding of cosmology. However\, many o
 f our predictions of non-linear structure formation are based on gravity o
 nly (i.e. dark matter only) N-body simulations because the simultaneous mo
 delling of lengths scales from a few parsecs for star formation to 100s of
  megaparsecs for the cosmic web is a prohibitively expensive process. In o
 rder to address any potential systematics arising from the neglect of bary
 ons\, we have performed a suite of cosmological\, fully hydrodynamic simul
 ations called the FLAMINGO simulations. Using these simulations\, we have 
 created realistic mock catalogues for the SDSS DR12 CMASS galaxy sample\, 
 a sample that is often used to derive cosmological constraints. From these
  catalogues we measure the projected correlation function\, monopole and q
 uadrupole correlation functions and compare these to observations to provi
 de a bound on the impact of baryons on large scale structure cosmology. We
  further investigate the effect of assuming different models for AGN\nfeed
 back and star formation.
