... ExtremelyRedObjects (EROs) As discussed in previous sections, ExtremelyRedObjects (EROs, i.e. galaxies with R K > 5) are very important because they allow us to select old passively evolving galaxies at z > 1. ...

... The most crucial probes of massive galaxy evolution are galaxies with the very red colors expected in case of passive evolution at z > 1 (e.g. R K s > 5, usually called ExtremelyRedObjects, EROs). ...
... Introduction Extremelyredobjects (R K > 5, EROs hereafter) are providing increasingly stringent constraints on our under- standing of the formation of galaxies in general, via their spectral evolution and clustering properties. ...
... Moreover, it appears that the spatial clustering of z p 3 LBGs is too low for them to be direct progenitors of z 1 extremelyredobjects and local massive galaxies (Daddi et al. ...

... We did this because a straight (i - z) color cut can select extremelyredobjects (EROs) as well as LBGs, but the spectral signatures of the two are distinct. ...
