Scientific paper

We propose to observe the starbursting dwarf galaxy NGC 3125 as part of a larger multi-wavelength project aiming to determine the energy efficiency of supernova feedback as a function of star formation intensity (SFI) and host galaxy mass (M). NGC 3125 occupies a particularly important region of the SFI/M parameter space, having a similar mass but much higher SFI than the dwarf starbursts previously observed with Chandra. ACIS-S observations will determine the radiative energy losses, mass cooling rate, temperature, abundance ratios and extent of hot X-ray emitting plasma in what we expect to be a vigorous superwind. These observations will complement proposed Cycle 15 HST ACS+WFPC2 observations of warm ionized gas, yielding a complete view of feedback radiative energy losses.
