Data and physics in nearby galaxies

<p>Galaxies are the places where stars are born, live, and die, recycling their newly-produced elements into the </p> <p>next generation of stars and planets. Many different physical processes are involved in this cycle: understanding theirinterplay in the interactions of the constituents of galaxies requires a combination of careful observations and detailed simulation. Combining observations at many different wavelengths of light constrains models of galaxy formation and evolution, allowing us to take apart and reconstruct the histories of these "island universes". The observational datasets we deal with are becoming vast and complex, requiring new approaches to data management and data analysis. </p> This talk will describe the challenges and some approaches, and highlight new results in the observational study of nearby galaxies with a particular focus on the Andromeda galaxy, the nearest large spiral.
