Gas and Stars in Galaxies - A Multi-Wavelength 3D Perspective
Matt Lehnert, Carlos De Breuck, Harald Kuntschner +1
An overview of the ESO/Radionet workshop devoted to 3D optical/near-infrared and sub-mm/radio observations of gas and stars in galaxies is presented. There will be no published pro…
Stellar population analysis on local infrared-selected galaxies
X. Y. Chen, Y. C. Liang, F. Hammer +2
To study the stellar population of local infrared galaxies, which contain star-forming galaxies, composite galaxies, LINERs, and Seyfert 2s. We also want to find whether infrared l…
Evolution of the Color-Magnitude Relation in Galaxy Clusters at z ~1 from the ACS Intermediate Redshift Cluster Survey
Simona Mei, Brad P. Holden, John P. Blakeslee +10
We apply detailed observations of the Color-Magnitude Relation (CMR) with the ACS/HST to study galaxy evolution in eight clusters at z~1. The early-type red sequence is well define…
Overview of the lithium problem in metal-poor stars and new results on 6Li
Roger Cayrel, Matthias Steffen, Piercarlo Bonifacio +2
Two problems are discussed here. The first one is the 0.4 dex discrepancy between the 7Li abundance derived from the spectra of metal-poor halo stars on the one hand, and from Big…
Pulsar Timing for the Fermi Gamma-ray Space Telescope
D. A. Smith, L. Guillemot, F. Camilo +25
We describe a comprehensive pulsar monitoring campaign for the Large Area Telescope (LAT) on the {\em Fermi Gamma-ray Space Telescope} (formerly GLAST). The detection and study of…
The WFI Halpha spectroscopic survey
Christophe Martayan, Dietrich Baade, Juan Fabregat
This document presents the results from our spectroscopic survey of Halpha emitters in galactic and SMC open clusters with the ESO Wide Field Imager in its slitless spectroscopic m…
