Vibrationally Excited Hcn in the Luminous Infrared Galaxy Ngc 4418

Infrared pumping and its effect on the excitation of HCN molecules can be important when using rotational lines of HCN to probe dense molecular gas in galaxy nuclei. We report the first extragalactic detection of (sub)millimeter rotational lines of vibrationally excited HCN, in the dust-enshrouded nucleus of the luminous infrared galaxy NGC 4418. We estimate the excitation temperature of Tvib ≈...

Fueling the gas debate.

All tools in the DAVID Bioinformatics Resources aim to provide functional interpretation of large lists of genes derived from genomic studies. The newly updated DAVID Bioinformatics Resources consists of the DAVID Knowledgebase and five integrated, web-based functional annotation tool suites: the DAVID Gene Functional Classification Tool, the DAVID Functional Annotation Tool, the DAVID Gene ID ...

Atomic hydrogen in the spiral galaxy NGC 3631

New high resolution, high sensitivity WSRT H i synthesis observations of the spiral galaxy NGC 3631 are presented. In the total atomic hydrogen map, the spiral arms are well distinguished from the interarm regions, while the sensitivity allows detection of H i in all but a few isolated regions of the areas between the spiral arms. Most of the atomic hydrogen is located within the optical disc, ...

Atomic and molecular gas in the starburst galaxy NGC 4945 ? , ? ?

Spatial and kinematical correlations between the H i and 12CO(2−1) emission of the southern spiral galaxy NGC4945 are studied with a common angular resolution of ∼ 23′′ (corresponding to 750 pc at D = 6.7 Mpc) and a velocity resolution of ∼7 kms−1. The 1.4 GHz continuum emission is also observed. The H i kinematics yield a galaxy mass of ∼ 1.4× 10 M within radius R=380′′, with molecular and neu...
