The distribution of outflow velocity v_out in DESI DR1 LRDs in this work, local low-mass galaxies with high sSFR (Y. Xu et al. 2022), z = 3 − 9 galaxies (S. Carniani et al. 2024; R. A. Cooper et al. 2025), and AGNs (M. Karouzos et al. 2016; C. M. Manzano-King et al. 2019; S. Salehirad et al. 2025). All of the literature v_out values are calculated with the definition in Equation (6), using the reported velocity offsets and FWHMs. The v_out values for AGNs in S. Salehirad et al. (2025) correspond to sources classified as AGNs in all three BPT diagrams ([N II], [S II], and [O I]).
