Abstract

The advent of two new instruments SAM-FP on the SOAR telescope and T80-South gives us a unique chance now to explore a number of studies of nearby galaxy structure, chemical enrichment, formation and evolution. The overall goal that both instruments allow is the study of evolution processes of star formation in disks of nearby galaxies, including our own Galaxy, in environments of different densities. We are interested in studying gaseous and stellar kinematics, dynamics and chemistry of galaxies at high spatial and spectral resolutions and the relation with their environments. The instrument SAM-FP is yielding superb high spatial resolution maps of the internal kinematics of galaxies, such as the Large Magellanic Cloud (LMC), and galaxies in nearby groups, thanks to ground-layer adaptive optics with laser correction, the only instrument of its kind in the world. On the other hand, the T80-South robotic telescope + imager with a 1.4 x 1.4 deg field-of-view is producing images of vast areas of the southern sky in 12 optical bands. The main objective of this proposal is to maximize the science return of these two instruments. We will study the LMC and a few nearby groups of galaxies, in particular galaxies in the Hydra cluster. The combination of these two data sets will allow us to look from small scales (centers of the sources) to large scales (whole galaxy, group and cluster as a whole as well as neighborhood), probing star formation properties. An additional goal is to allow the SOAR community to use SAM-FP and to plan an upgrade of this instrument. (AU)
