Zhang,其速度高达约8, and could reach the circumgalactic medium or even the intergalactic medium. The average kinetic energy outflow rate of our sample is more than 2dex higher than that of the lower-redshift comparison samples. The substantially higher frequency of outflows with energetics well above the threshold for negative feedback in our sample strongly suggests that quasar feedback plays an important part in efficiently quenching and regulating early massive galaxies.
