We present images of the Vega system obtained with the IRAM Plateau de Bure interferometer at a 1.3 mm wavelength with submillijansky sensitivity and ∼2 .5 resolution (about 20 AU). These observations clearly detect the stellar photosphere and two dust emission peaks offset from the star by 9 .5 and 8 .0 to the northeast and southwest, respectively. These offset emission peaks are consistent wi...

Combining mid-infrared data from the SPITZER Space Telescope with cold gas and dust emission observations from the Plateau de Bure Interferometer, we characterize the Infrared Dark Cloud IRDC 18223-3 at high spatial resolution. The millimeter continuum data reveal a massive ∼184M⊙ gas core with a projected size of ∼28000AU that has no associated protostellar mid-infrared counterpart. However, t...

We present CO(1–0) and CO(2–1) line emission maps of the barred spiral active galaxy HE 1029-1831 (z=0.0403) obtained with the IRAM Plateau de Bure Interferometer (PdBI) and in part by the Berkeley-Illinois-Maryland Association (BIMA) observatory. The CO emission is well associated with the optical bar and extended along it. The FWHM of the CO emission is estimated to be ∼(6±2) kpc. The CO emis...

We have designed and tested a digital spectrometer suitable for analyzing 8 GHz baseband signals. It is based on a 16Gsps, 5-bit ADC from e2v and a Stratix-IV FPGA employed for later filtering and signal processing. Digitized data is received and synchronized via twenty high-speed 4-Gbps transceivers integrated in the FPGA. A 64-channel polyphase filter bank separates the input signal into 250-...

We report high-resolution millimeter mapping with the IRAM Plateau de Bure interferometer of rest-frame 335μm continuum and CO(3–2) line emission from the z = 2.8 submillimeter galaxy SMMJ02399-0136. The continuum emission comes from a ∼ 3 diameter structure whose elongation is approximately east-west and whose centroid is coincident within the astrometric errors with the brightest X-ray and re...

We report the detection of the 3 P1→ 3 P0 fine-structure line of neutral carbon in the z = 4.12 quasar PSS 2322+1944, obtained at the IRAM Plateau de Bure interferometer. The [Ci] 3 P1 − 3 P0 line is detected with a signal-to-noise ratio of ∼ 6 with a peak intensity of ≈ 2.5 mJy and a velocity-integrated line flux of 0.81 ± 0.12 Jy km s −1. Assuming an excitation temperature of 43 K (equal to t...

We report IRAM Plateau de Bure, millimeter interferometry of three z ∼2.4 to 3.4, SCUBA deep field galaxies. Our CO line observations confirm the rest-frame UV/optical redshifts, thus more than doubling the number of confirmed, published redshifts of the faint submillimeter population and proving their high-z nature. In all three sources our measurements of the intrinsic gas and dynami-cal mass...

We present CO(1–0) and CO(2–1) line emission maps of the barred spiral active galaxy HE 1029-1831 (z = 0.0403) obtained with the IRAM Plateau de Bure Interferometer (PdBI) and in part by the Berkeley-Illinois-Maryland Association (BIMA) observatory. The CO emission is well associated with the optical bar and extended along it. The FWHM of the CO emission is estimated to be ∼(6 ± 2) kpc. The CO ...

We present the first observations of molecular line emission inNGC 3718 with the IRAM 30m and the Plateau de Bure Interferometer. This galaxy is an impressive example for a strongly warped gas disk harboring an active galactic nucleus (AGN). An impressive dust lane is crossing the nucleus and a warp is developing into a polar ring. The molecular gas content is found to be typical of an elliptic...
