Interferometric observations of nearby galaxies
This contribution presents a short overview about the investigation of the molecular gas content of nearby galaxies using the Plateau de Bure Interferometer. I try to give a rather complete list of recent references, and explicit descriptions are given for objects under study at RAI Bonn. They comprise very different types of galaxies such as Haro 2, Mrk 297, M82, NGC2146, M31 and NGC4258. All ...
متن کاملHi Observations of Five Groups of Galaxies
We present the results of HI observations of five groups of galaxies spanning a range of velocity dispersion and spiral fraction (brightest optical group member in parenthesis): NGC 7582 (NGC 7552), USGC U207 (NGC 2759), USGC U070 (NGC 664), USGC U412 (NGC 3822), USGC U451 (NGC 4065). Neutral intragroup gas is detected in three of the five groups. We present the discovery of a previously uncata...
متن کاملHI observations of dwarf galaxies in voids ?
We report HI-observations of a sample of 43 optically selected galaxies from the Heidelberg-void project. Only emission line galaxies have been selected. The HI-detection rate was 67%. The observed sample is a mix in late-type morphology objects with a spread in luminosity. They were compared to other samples with similar selection effects and mixtures. The detected galaxies have a high HI cont...
متن کاملChandra Observations of Nearby Spiral Galaxies
Chandra is revolutionising our understanding of the X-ray emission from spiral galaxies. Before Chandra, detailed extragalactic studies were limited to Local Group galaxies. We are now able to obtain detailed inventories of sources in galaxies outside the Local Group, allowing population studies for the first time. In this review I will first discuss some intriguing observations of globular clu...
متن کاملCompleting HI observations of galaxies in the Virgo Cluster
High sensitivity (rms noise ∼ 0.5 mJy) 21-cm H i line observations were made of 33 galaxies in the Virgo cluster, using the refurbished Arecibo telescope, which resulted in the detection of 12 objects. These data, combined with the measurements available from the literature, provide the first set of H i data that is complete for all 355 late-type (Sa-Im-BCD) galaxies in the Virgo cluster with m...
