Enhanced Preheating after Multi-Field Inflation: On the Importance of being Special

Thorsten Battefeld, Alexander Eggemeier, John T. Giblin

We discuss preheating after multi-field inflation in the presence of several preheat matter fields that become light in the vicinity of (but not at) the inflatons' VEV, at distinct…

The metallicity profile of M31 from spectroscopy of hundreds of HII regions and PNe

Nathan Sanders, Nelson Caldwell, Jonathan McDowell +1

The oxygen abundance gradients among nebular emission line regions in spiral galaxies have been used as important constraints for models of chemical evolution. We present the large…

A Massive, Cooling-Flow-Induced Starburst in the Core of a Highly Luminous Galaxy Cluster

M. McDonald, M. Bayliss, B. A. Benson +83

In the cores of some galaxy clusters the hot intracluster plasma is dense enough that it should cool radiatively in the cluster's lifetime, leading to continuous "cooling flows" of…

Evolution of the Most Massive Galaxies to z ~ 0.6: II. The link between radio AGN activity and star formation

Yan-Mei Chen, Guinevere Kauffmann, Timothy M. Heckman +6

We analyze the optical spectra of massive (log M*/Msun > 11.4) radio-loud galaxies at z~0.2 and z~0.6. By comparing stellar population parameters of these radio-loud samples with r…
