Higher-resolution optical spectra of

Galactic outflows are predicted to be ubiquitous in low-mass galaxies, but observational evidence is lacking. Both a low signal-to-noise ratio and a low spectral resolution can severely hamper the detection of galactic outflows, especially in small galaxies that have intrinsically narrow spectral lines. In an effort to overcome these issues, we obtained new, medium-high resolution (FWHMinst ∼ 50 − 110 km/s) optical spectra of 52 local star-forming galaxies (0.01 10−0.74 M⊙/yr). We estimate ionized gas mass outflow rates ranging from ∼0.1 − 50 × 10−3 M⊙/yr (mean ∼20 × 10−3 M⊙/yr) and corresponding mass loading factors between 0.03 and 0.14 (mean ∼0.07) for the sample.
