Context. The bipolar HH 212 outflow has been mapped in SiO using the extended configuration of the Plateau de Bure Interferometer (PdBI), revealing a highly collimated SiO jet closely associated with the H2 jet component. Aims. We study at unprecedented resolution (0. ′′34 across the jet axis) the properties of the innermost SiO “microjet” within 1000 AU of this young Class 0 source, to compare...
We present an analysis of far–infrared (FIR) [CII] and [OI] fine structure line and continuum observations obtained with Herschel/PACS, and 12CO(1–0) observations obtained with the IRAM Plateau de Bure Interferometer, of Lyman-break analogs (LBAs) at z ∼ 0.2. The principal aim of this work is to determine the typical interstellar medium (ISM) properties of z ∼ 1−2 main sequence (MS) galaxies, w...
We have detected emission by the CO(5–4) and (6–5) rotational transitions at from the z p 5.7722 0.0006 host galaxy of the SDSS quasar J0927 2001 using the Plateau de Bure Interferometer. The peak line flux density for the CO(5–4) line is mJy, with a line FWHM p 610 110 km s . The implied molecular gas 1 0.72 0.09 mass is M . We also detect the 90 GHz continuum at mJy, consistent with a 10 (1.6...
We present the first results of a high-resolution study of the distribution and kinematics of molecular gas in two nearby radio galaxies, 4C 31.04 and 3C 293, representative of two different stages of evolution in radio-loud active galactic nuclei (AGN). These observations, conducted with the IRAM Plateau de Bure Interferometer (PdBI), map with unprecedented spatial resolution (∼0.5 ′′ –1 ′′) a...
We have accumulated CO(1-0) and (2-1) data of several GMCs in M31 using the Plateau de Bure Interferometer. The sample covers a range of 5 to 18 kpc galactocentric distance and various physical conditions. The spatial resolution attains values down to 3 pc. All GMCs investigated have been resolved into several components, also seemingly quiescent clouds and not only the cases where already the ...
Sub-arcsecond IRAM Plateau de Bure mm-interferometric observations of the CO (2-1) line emission in the Seyfert 1 NGC 3227 and the Seyfert 2 NGC 1068 have revealed complex kinematic systems in the inner 100 pc to 300 pc that are not consistent with pure circular motion in the host galaxies. Modeling of these kinematic systems with elliptical orbits in the plane of the host galaxy (representing ...
Cold molecular gas is found in several clusters of galaxies (Edge, 2001, Salomé & Combes, 2003): single dish telescope observations in CO(1-0) and CO(2-1) emission lines have revealed the existence of large amounts of cold gas (up to ∼10 11 M ⊙) in the central region of cooling flow clusters. We present here interferometric observations performed with the IRAM Plateau de Bure interferometer in ...
Using the Plateau de Bure Interferometer and IRAM 30m Telescope, we observed λ2-3mm absorption lines of CS, SO, SO2, H2S and HCS + from some of the diffuse clouds which occult our well-studied sample of compact extragalactic mm-wave continuum sources. Our observations of SO, H2S and HCS + represent the first detections of these species in diffuse clouds; SO2 was not detected at all. We find a t...
We recently found extended CO(2–1) emission from cold molecular gas embedded in the network of Hα filaments surrounding the galaxy NGC 1275 (Salome et al. 2006). We now present CO(2–1) interferometer maps of the eastern filaments, at high spatial and spectral resolutions. The cold molecular gas is detected by the Plateau de Bure Interferometer along the eastern filaments over an extent of 15′′,...
Observational constraints provided by high resolution and high sensitivity observations of external galaxies made in the millimetre and sub-millimetre range have started to put on a firm footing the study of the extragalactic chemistry of molecular gas. In particular, the availability of multi-species and multi-line surveys of nearby galaxies is central to the interpretation of existent and for...
