Observational properties of the ionized outflow in BOSS-EUVLG1 (yellow star) together with samples of star-forming galaxies (SFGs) at intermediate redshifts including 0.6 < z < 2.7 SFGs (red dots) from the KMOS^3D survey (Förster Schreiber et al. 2019, values of V_out are a priv. comm.), SFGs at z ∼ 1 (magenta dots) from KMOS observations (Swinbank et al. 2019), SFGs at z ∼ 2 (green dots) from the MOSDEF survey Freeman et al. (2019), and SFGs at z∼2 (blue dots) from the SINS and zC-SINF surveys (Newman et al. 2012). Low-z (ultra-)luminous galaxies (cyan and orange dots) are also represented (Arribas et al. 2014). Upper panels: flux ratio of the broad to narrow Hα line components (F_B/F_N) as a function of the SFR (left) and M_stellar (right). Bottom panels: outflow velocity as a function of the SFR (left) and M_stellar (right). The continuum line in the V_out to SFR relation defines the best fit (V_out = 148 × SFR^0.23) to the BOSS-EUVLG1, low- and intermediate-z data points. The dashed line represents the V_out to Hα-derived SFR relation derived for the low-z sample of U/LIRGs without AGNs (Arribas et al. 2014).
