We study winds in 12 X-ray AGN host galaxies at z ~ 1. We find, using thelow-ionization Fe II 2586 absorption in the stacked spectra, that theprobability distribution function (PDF) of the centroid velocity shift in AGNhas a median, 16th and 84th percentiles of (-87, -251, +86) km/s respectively.The PDF of the velocity dispersion in AGN has a median, 84th and 16thpercentile of (139, 253, 52) km/s respectively. The centroid velocity and thevelocity dispersions are obtained from a two component (ISM+wind) absorptionline model. The equivalent width PDF of the outflow in AGN has median, 84th and16th percentiles of (0.4, 0.8, 0.1) Angstrom. There is a strong ISM componentin Fe II 2586 absorption with (1.2, 1.5, 0.8) Angstrom, implying presence ofsubstantial amount cold gas in the host galaxies. For comparison, star-formingand X-ray undetected galaxies at a similar redshift, matched roughly in stellarmass and galaxy inclination, have a centroid velocity PDF with percentiles of(-74, -258, +90) km/s, and a velocity dispersion PDF percentiles of (150, 259,57) km/s. Thus, winds in the AGN are similar to star-formation-driven winds,and are too weak to escape and expel substantial cool gas from galaxies. Oursample doubles the previous sample of AGN studied at z ~ 0.5 and extends theanalysis to z ~ 1. A joint reanalysis of the z ~ 0.5 AGN sample and our sampleyields consistent results to the measurements above.
