Notes. (a) SFR derived from the IR luminosity assigned to each nucleus (see Sect. 3.4.1) using the calibration of Kennicutt & Evans (2012). This is the adopted SFR for these nuclei. (b)SFR derived from the non-thermal radio continuum using the Murphy et al. (2011) SFR calibration (see Sect. 3.4.2). (c) Logarithm of the mass loading factor η = Ṁout∕SFR(IR). (d) Ratio between theoutflow momentum rate and the momentum injected by supernova explosions. We assume that the PSN per SN is 1.3 × 105 M⊙ km s−1 × (n0∕100 cm−3)−0.17 (Kim & Ostriker 2015) using n0 = 100 cm−3 and that the SN rate, νSN (yr−1), is 0.012 × SFR(IR) (M⊙ yr−1) for the adopted IMF (Leitherer et al. 1999). (e)Ratio between thetotal kinetic luminosity of the molecular outflow and that injected by supernova explosions (LSNe (erg s−1) = 9 × 1041 SFR(IR) (M⊙ yr−1); Leitherer et al. 1999, adapted for a Kroupa 2001 IMF).
