Spectra of Cluster Galaxies at Z ∼ 0.4

The “MORPHS” group has obtained an extensive spectroscopic dataset of galaxies in the fields of 10 rich clusters at 0.37 < z < 0.56; the stellar population properties of about 700 objects have been determined from a detailed analysis of spectral line strenghts and colours, up to a galactic absolute magnitude MV = −20.3 mag. Morphological informations for a consistent fraction of our sample have...

A survey of the cold molecular gas in gravitationally lensed star - forming galaxies at z > 2

Using the Australia Telescope Compact Array (ATCA), we conducted a survey of CO J = 1− 0 and J = 2− 1 line emission towards strongly lensed high-redshift dusty star forming galaxies (DSFGs) previously discovered with the South Pole Telescope (SPT). Our sample comprises 17 sources that had CO-based spectroscopic redshifts obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) and ...

Molecular Gas in Submillimetre-Faint, Star-Forming Ultraluminous Galaxies at z>1

We present interferometric CO observations of twelve z∼2 submillimetre-faint, starforming radio galaxies (SFRGs) which are thought to be ultraluminous infrared galaxies (ULIRGs) possibly dominated by warmer dust (Tdust > ∼ 40 K) than submillimetre galaxies (SMGs) of similar luminosities. Four other CO-observed SFRGs are included from the literature, and all observations are taken at the Plateau...

A Massive Cluster of Galaxies at Z = 0.996

We report the identiication of a cluster of galaxies around the high-redshift radio galaxy 3CR184 at z = 0.996. The identiication is supported by an excess of galaxies observed in projection in I band images (both in ground-based and HST data), a peak in the redshift distribution comprising 11 galaxies (out of 56 with measured redshifts) in a 2000 km s ?1 velocity interval, and the observation ...

Molecular Gas in Galaxies

Knowledge of the molecular component of the ISM is fundamental to understand star formation. The H2 component appears to dominate the gas mass in the inner parts of galaxies, while the HI component dominates in the outer parts. Observation of the CO and other lines in normal and starburst galaxies have questioned the CO-to-H2 conversion factor, and detection of CO in dwarfs have shown how sensi...
