The Adriatic severe bora can partly be explained by the two-dimensional hydraulic theory, as one of the possible mechanisms of a strong surface downslope wind. A comparison of the application of the hydraulic theory shows a similar severe bora mechanism on the northern and mid-Adriatic, with the exception of the Senj area where special bora effects have been observed. As the theory could not co...
We report high angular resolution IRAM Plateau de Bure interferometric observations of the SiO v = 0 J = 2→1 and J = 5 → 4 transitions in the southern lobe of the young L 1157 molecular outflow. The resolution of these observations (∼ 2.5′′) makes them directly comparable to available highresolution CO maps of the flow. The known precession of the L 1157 flow is fully confirmed. We find a remar...
Context. Observations of the CO J(1–0) 115 GHz and J(2–1) 230 GHz lines in comet C/1995 O1 (Hale-Bopp) were performed with the IRAM Plateau de Bure interferometer on 11 March, 1997. The observations were conducted in both single-dish (ON–OFF) and interferometric modes with 0.13 km s spectral resolution. Images of CO emission with 1.7 to 3′′ angular resolution were obtained. Aims. The ON–OFF and...
Using the Plateau de Bure interferometer, we observed the λ3mm absorption lines of CN, HCN and HNC from some of the diffuse clouds which lie toward our well-studied sample of compact extragalactic mm-wave continuum sources. The column densities of these species all vary by a factor of about fifty and are prominent in only a limited subset of the clouds seen in the most ubiquitous species such a...
We present deep IRAM Plateau de Bure Interferometer (PdBI) observations, searching for CO-emission toward two massive, non-lensed Lyman break galaxies (LBGs) at z = 3.216 and 4.058. With one low significance CO detection (3.5σ) and one sensitive upper limit, we find that the CO lines are &3–4 times weaker than expected based on the relation between IR and CO luminosities followed by similarly, ...
Using the Plateau de Bure interferometer, we searched for thermal SiO J=1-2 absorption at 86 GHz from the diffuse and translucent clouds which lie toward our sample of extragalactic continuum sources. SiO is present at a level N(SiO)/N(HCO+) ≈ 0.01 − 0.1, or N(SiO)/N(H2) ≈ 2 × 10−11 − 2 × 10−10. N(SiO) declines with increasing N(HCO+) and with increasing thermal pressure measured in the J=1-0 l...
