We present a high-resolution spectroscopic study of the envelope of the young Class 0 protostar IRAM 04191+1522 in Taurus. N 2 H + (1-0) observations with the Plateau de Bure Interferometer and the IRAM 30m telescope demonstrate that the molecular ion N 2 H + disappears from the gas phase in the inner envelope (r < 1600 AU, n H 2 > 4 − 7 × 10 5 cm −3). This may result from N 2 depletion on pola...

Using the IRAM 30m telescope we detected the lower fine structure line of neutral carbon (C

integration of memory on the same die as the processor (IRAM) has the potential to offer unprecedented bandwidth that can be exploited efficiently by vector processors. However, real-world scientific vector applications with their very large memory requirements and their poor locality, would easily overflow any single IRAM device. In this environment, traditional approaches such as caching or p...

The nuclei of active comets emit molecules anisotropically from discrete vents. As the nucleus rotates, we expect to observe periodic variability in the molecular emission line profiles, which can be studied through mm/submm spectroscopy. Using this technique Based on observations carried out with the IRAM 30-m, JCMT 15-m, and CSO 10.4-m telescopes. IRAM is supported by INSU/CNRS (France), MPG ...

Simulation of interferometry observations, including pointing errors, phase noise and thermal noise. The result is a UV table whose visibilities have been computed along the tracks for each pair of antennas. Depending on the input image size, the simulator automatically shifts between single field and mosaic modes. The interferometry simulation can be made at the same time for two antenna diame...
