摘要：
We report on a sample of 48 nearby, star-forming galaxies observed with the Cosmic Origin Spectrograph on the Hubble Space Telescope. We measure the kinematics of warm gas in galactic outflows using a combination of four Si II absorption lines. We use multi-wavelength ancillary data to estimate stellar masses (M-*), star formation rates (SFR), circular velocities (v(circ)), and morphologies. The galaxies cover four orders of magnitude in M-* and SFR, and sample a wide range of morphologies from starbursting mergers to normal star-forming galaxies. We derive 3.0-3.5 relations between outflow velocity and SFR, M-*, and v(circ). The outflow velocities scale as SFR0.08-0.22, M-*(0.12-0.20) and v(circ)(0.44-0.87), with the range depending on whether we use a maximum or a central velocity to quantify the outflow velocity. After accounting for their increased SFR, mergers drive 32% faster outflows than non-merging galaxies, with all of the highest velocity outflows arising from mergers. Low-mass galaxies (log (M-*/M-circle dot) < 10.5) lose some low-ionization gas through galactic outflows, while more massive galaxies retain all of their low-ionization gas, unless they undergo a merger.
