Quasar spectra show signatures of energetic outflows originating from the accretion disk as absorption features. These outflows are like winds, carrying energy and matter from the center of the quasar outwards their host galaxies. Extremely high-velocity outflows (EHVOs) are those winds moving at speeds between 0.1c and 0.2c in the UV/optical spectra. Ultra-Fast-Outflows (UFOs) are defined as highly ionized outflows, which have average velocities ranging from 0.1c and 0.3c detected in the X-Ray spectrum.
