We present the first interferometric observations of CO(1–0) and CO(2–1) line emission from the warped LINER NGC 3718, obtained with the IRAM Plateau de Bure Interferometer (PdBI). This L1.9 galaxy has a prominent dust lane and on kiloparsec scales, a strongly warped atomic and molecular gas disk. The molecular gas is closely associated with the dust lane across the nucleus and its kinematic ce...

We investigate the CO excitation of normal (near-IR selected BzK) star-forming (SF) disk galaxies at z = 1.5 using IRAM Plateau de Bure observations of the CO[2–1], CO[3–2], and CO[5–4] transitions for four galaxies, including VLA observations of CO[1–0] for three of them, with the aim of constraining the average state of H2 gas. By exploiting previous knowledge of the velocity range, spatial e...

Context. We present observations of rotational lines of H 2 S, SO and CS performed in comet C/1995 O1 (Hale-Bopp) in March 1997 with the Plateau de Bure interferometer of Institut de Radioastronomie Millimétrique (IRAM). Aims. The observations provide informations on the spatial and velocity distributions of these molecules. They can be used to constrain their photodissociation rate and their o...

the date of receipt and acceptance should be inserted later Abstract. We report high angular resolution (HPBW∼ 0.6 ′′ × 0.5 ′′ at 1.3mm) observations of the Class 0 intermediate-mass (IM) protostar NGC 7129–FIRS 2 using the Plateau de Bure Interferometer. Our observations show the existence of an intense unresolved source in the continuum at 1.3mm and 3mm at the position of the Class 0 object. ...

CO radio line observations with the IRAM Plateau de Bure interferometer show that the carbon star TT Cyg is surrounded by a large (radius ∼35′′ or 2.7×1017 cm), geometrically thin (average width ∼2. ′′5 or 1.9×1016 cm) shell of gas, which has a remarkable overall spherical symmetry (e.g., its radius varies by less than ±3%). It expands with a velocity of ∼12.6 km s−1. The emitting gas is very e...

We used the Plateau de Bure Interferometer (PdBI) to map a sample of 15 submillimetre galaxies (SMGs) in the COSMOS field at the wavelength of 1.3 mm. The target SMGs were originally discovered in the James Clerk Maxwell Telescope (JCMT)/AzTEC 1.1 mm continuum survey at S/N1.1 mm = 4 − 4.5. This paper presents, for the first time, interferometric millimetre-wavelength observations of these sour...

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...

Aims. Our goal is to study molecular gas properties in nuclei and large scale outflows/winds from active galactic nuclei (AGNs) and starburst galaxies. Methods. We obtained high resolution (0. ′′25 to 0. ′′90) observations of HCN and HCO J = 3 → 2 of the ultraluminous QSO galaxy Mrk 231 with the IRAM Plateau de Bure Interferometer (PdBI). Results. We find luminous HCN and HCO J = 3 → 2 emission...

We have observed four carbon stars (W Ori, RW LMi [CIT6], Y CVn, and LP And [IRC+40540]) in the HCN(J = 1 → 0) line and three of them (RW LMi, Y CVn, and LP And) also in the CN(N = 1 → 0) line using the IRAM interferometer on Plateau de Bure. The HCN brightness distributions are centred on the stellar positions suggesting a photospheric origin of this molecule. We see the expected structure of ...

We have used the IRAM Plateau de Bure millimeter interferometer and the UKIRT 1– 5μm Imager Spectrometer (UIST) to test the connection between the major phases of spheroid growth and nuclear accretion by mapping CO emission in nine submillimetredetected QSOs at z = 1.7–2.6 with black hole (BH) masses derived from near-infrared spectroscopy. When combined with one QSO obtained from the literatur...
