Velocity relative to systemic of the outflowing component vs. SFR of the host galaxy for samples analyzed on the basis of 1D (i.e., integrated and long-slit, left) and 2D (IFS, right) data. The present sample is represented with black filled symbols in both panels. We identify pure starbursts and AGN hosts with squares and circles, respectively, while very strong AGN are indicated with an additional circle. In the left panel, other [U]LIRGs samples from Rupke et al. (2002, 2005b), and Martin (2005) are indicated with red diamonds, light blue crosses, and blue triangles, respectively. In the right panel, green diamonds indicate the IFS-based major-merger ULIRGs results by Rupke & Veilleux (2013) and the orange asterisk shows the result for the wind in M100 obtained by Jiménez-Vicente et al. (2007). The pink lines, in both panels, represent the trends of the type V ∝ SFRⁿ found for our samples (excluding the strongest AGNs). See text for details. The shaded gray bands indicate uncertainties.
