Quantifying Star Formation and Feedback: The M81 Group Dwarf Galaxies Studies of the impact of star formation via stellar winds and supernovae ('feedback') on the properties of a galaxy are of fundamental importance to understanding galaxy evolution. One crucial aspect in these studies is a precise census of the recent star formation in a galaxy. The aim of this proposal is to obtain spatially resolved star formation histories with a time resolution of roughly 30 Myr over the last 500 Myr in a carefully designed sample using the absolutely unique capabilities of the ACS. Our sample comprises 10 galaxies in the M81 group which is host to a wide diversity of dwarf star forming galaxies. They span ranges of 6 magnitudes in luminosity, 1000 in current star formation rate, and 0.5 dex in metallicity. The ACS observations will allow us to directly observe the strength and spatial relationships of all of the star formation in these galaxies in the last 500 Myr. We can then quantify the star formation and measure (1) the fraction of star formation that is triggered by feedback, (2) the fraction of star formation that occurs in clusters and associations, and (3) to what degree future star formation is governed by the feedback from previous star formation. The ACS observations will be complemented with high-quality ancillary data collected by our team for all galaxies (e.g., Spitzer, UV/optical/NIR, VLA HI). We will calculate the energy created by star formation events and compare it to the estimated energy deposited into the local ISM. This will enable us to construct prescriptions of how star formation and feedback depend on metallicity, size, gas content, and current star formation rates in galaxies. Our resolved star formation maps will be compared with star formation rates inferred from H-alpha, UV, and IR observations - allowing an independent calibration of these techniques. Recent ACS imaging by us of one galaxy in the same group clearly demonstrates the feasibility of the proposed program. Most of the sample galaxies are located in the CVZ, making this an extremely efficient program.
The goal of this proposal is to construct and interpret global and spatially resolved star formation histories (SFHs) for the M81 group dwarf galaxies. This is done by creating color-magnitude diagrams (CMDs) and then using stellar evolution models to convert these CMDs into SFHs. Because all of the M81 dwarfs are at high Galactic latitude and most of them are located in the CVZ, deep imaging can be achieved efficiently. V and I band imaging will be obtained using the ACS (4000s in both F555W and F814W). This can be achieved with 2 CVZ orbits (and 4 orbits for the 2 non-CVZ galaxies). This will allow us to reach to 27.5 mag. (M_V ~ -0.5) in V and 26.8 mag. in I at a S/N of 5 (`optimal' S/N = 10). The majority (7) of the sample can be covered in one pointing per galaxy. For the three larger galaxies we are proposing multiple pointings so that we can cover a large fraction of the optically visible galaxy; these systems are critical to the experiment in order to provide a statistically significant sample of star forming ``cells'' and to study the interactions of different regions of star formation. In the case of IC 2574, we will add two pointings to the one field that we have already imaged. Because we are focused on the recent star forming events for the purpose of quantifying feedback, we will cover all of the active star forming regions in these galaxies, but not extend the coverage to the limit of the HI or D_25. Previous observations of Local Group dwarf galaxies indicate that complete radial coverage in this manner would roughly triple the observing time and yield very little additional recent star formation. This program poses no real-time or special scheduling requirements. This program poses no special calibration sequences.
