Abstract

We analyse the large-scale clustering in Fourier space of emission line galaxies (ELG) from the Data Release 16 of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spectroscopic Survey. The ELG sample contains 173 736 galaxies covering 1170 deg2 in the redshift range 0.6 eff = 0.845 we measure DV(zeff)/rdrag = 18.33+0.57-0.62, with DV the volume-averaged distance and rdrag the comoving sound horizon at the drag epoch. In combination with the RSD measurement, at zeff = 0.85 we find fσ8(zeff) = 0.289+0.085-0.096, with f the growth rate of structure and σ8 the normalization of the linear power spectrum, DH(zeff)/rdrag = 20.0+2.4-2.2 and DM(zeff)/rdrag = 19.17 ± 0.99 with DH and DM the Hubble and comoving angular distances, respectively. These results are in agreement with those obtained in configuration space, thus allowing a consensus measurement of fσ8(zeff) = 0.315 ± 0.095, DH(zeff)/rdrag = 19.6+2.2-2.1 and DM(zeff)/rdrag = 19.5 ± 1.0. This measurement is consistent with a flat ΛCDM model with Planck parameters.
