STAR FORMATION IN THE DESERT: PROBING THE LOW-DENSITY EXTREMES

Over the past decade multi-wavelength observations have revealed the extraordinary ubiquity and diversity of star formation in galaxies, ranging over billionfold ranges in star formation rates (SFRs), whether expressed in absolute terms, or in terms of areally or mass-normalised SFRs. Considerable attention has been focussed on the high-density extremes in starbursts and galactic nuclei, but much can be learned as well from star formation in low-density regimes-- in the outermost discs of spiral galaxies, and in early-type galaxies, low surface brightness galaxies, and extreme ...

ON THE FORMATION OF MASSIVE GALAXIES

Looking backwards we have been able to reconstruct from the detailed structure of our own Galaxy and from the fossil evidence derived from the study of nearby galaxies a plausible history of how galaxies formed over the last several billion years. In addition, now that we have a quite definite cosmological model, providing us with a quantitative picture of how perturbations grew from very low amplitude Gaussian fluctuations, we can perform the forward modeling of representative pieces of the universe using standard physical processes ...

Competition and Cooperation

Numerous applications of economics are based on models that assume individual economic actors take prices as given. Indeed, this assumption underlies many empirical studies. The question of whether such an assumption can be justified as arising in the context of individual and group optimizing behavior has been the subject of extensive investigation.One answer to the question originates with the work of Edgeworth (1881), which argues that groups individuals cannot improve upon their part of a price-taking economic equilibrium by cooperation, that is, the set of outcomes that are stable against collective activities of groups – the core-- is equivalent to ...
