CI and CO in nearby galaxy centers

Co and [ci] in Galaxy Centers

Measurements of [CI], J=2–1 13 CO and J=4–3 12 CO emission from quiescent, starburst and active galaxy centers reveal a distinct pattern characterized by relatively strong [CI] emission. The [CI] to 13 CO emission ratio increases with central [CI] luminosity. It is lowest in quiescent and mild starburst centers and highest for strong starburst centers and active nuclei. C • abundances are close...

CI and CO in the nearby spiral galaxies IC 342 and Maffei 2

We present J=2–1, J=3–2, J=4–3 CO and 492 GHz [CI] maps as well as J=2–1 and J=3–2 CO measurements of the central regions in the nearby Sc galaxies IC 342 and Maffei 2. In both galaxies. the distribution of CO and [CI] is strongly concentrated towards the center. These centers harbour modest starbursts. Both galaxies have nearly identical CO transitional ratios but the relative intensities of t...

Effect in Nearby Galaxy Clusters

We present H 0 results from Cosmic Background Imager (CBI) observations of the Sunyaev-Zel'dovich Effect (SZE) in 7 galaxy clusters, A85, A399, A401, A478, A754, A1651, and A2597. These observations are part of a program to study a complete, volume-limited sample of low-redshift (z < 0.1), X-ray selected clusters. Our focus on nearby objects allows us to study a well-defined, orientation unbias...

The Nearby Field Galaxy

Globular Clusters in nearby Galaxy Clusters

The discovery of a large population of intra-cluster star clusters in the central region of the Hydra I and Centaurus galaxy clusters is presented. Based on deep VLT photometry (V, I), many star clusters have been identified not only around the early-type galaxies, but also in the intra-cluster field, as far as 250 kpc from the galaxy centres. These intra-cluster globulars are predominantly blu...
