For this week’s Journal Club, I am going to talk about the series of papers by Bovy et al. examining the structure of the Milky Way disk by analyzing chemical subsamples in the SEGUE G dwarf data set. Notably, they find that the disk is composed of a single component, rather than a distinct thin and thick disk. We discussed some of these briefly at Morning Coffee, but I think it is very useful to look at the three together as a whole.

Obscured Starburst Activity in High Redshift Clusters and Groups

We have used Spitzer-MIPS 24um imaging and extensive Keck  spectroscopy to identify and study the obscured star forming population in and around three clusters and three groups in the  Cl1604 supercluster at z~0.9.  We find that the average density of  24um-detected galaxies within the Cl1604 clusters is nearly twice  that of the surrounding field and that this overdensity scales with  the cluster’s dynamical state.  The 24um-bright members often appear  optically unremarkable and exhibit only moderate [OII] line emission  due to severe obscuration. Their spatial distribution suggests they are an infalling population, but an examination of their spectral properties, morphologies and optical colors indicate they are not simply analogs of the field population that have yet to be quenched.  Using stacked composite spectra, we find the 24um-detected cluster and group galaxies exhibit elevated levels of Balmer absorption compared to what is expected from normal, continuous star formation activity. A similar excess is not observed in field galaxies with equivalent infrared luminosities.  This implies a greater fraction of the detected cluster and group members are experiencing starburst activity compared to their counterparts in the field.  Using HST-ACS imaging we find that disturbed morphologies are common among the 24um-detected cluster and group members and become more prevalent in regions of higher galaxy density.  We conclude that mergers are the dominant triggering mechanism responsible for the enhanced star formation found in the Cl1604 groups, while a mix of harassment and mergers are likely driving the activity of the cluster galaxies.
