The Large Program "Astrochemical Surveys At IRAM" (ASAI) investigates the emergence of molecular complexity along different stages solar-type star formation process, by carrying out unbiased line surveys a sample ten template sources in range 80-272 GHz with IRAM 30m telescope. We present here an overview main results ASAI.

We have searched for molecular absorption lines at millimeter wavelengths in eleven gravitational lens systems discovered in the JVAS/CLASS surveys of flat spectrum radio sources. Spectra of only one source 1030+074 were obtained in the 3-, 2and 1.3-millimeter band at the frequencies corresponding to common molecular transitions of CO and HCO as continuum emission was not found in any of the ot...

Influence of prior Na1 pump activity on pump and Na1/Ca21 exchange currents in mouse ventricular myocytes. Am. J. Physiol. 275 (Heart Circ. Physiol. 44): H1808–H1817, 1998.—We examined the dependence of peak Na1 pump and Na1/Ca21 exchanger currents on prior Na1 pump inhibition induced by exposure to z...

This work presents an overview of the main results from EMIR Multi-Line Probe ISM Regulating Galaxy Evolution (EMPIRE) survey, IRAM-30m Large Program (∼ 500 h) which observed tracers high density molecular gas across disks nine nearby, star-forming galaxies. EMPIRE is first comprehensive and systematic study mapping high-density including HCN, HCO + HNC, as well optically thin J = 1−0 transitio...

Aims. Our aim is to unveil the physical conditions and structure of the intermediate mass (IM) protostar IRAS 21391+5802 (IC 1396 N) at scales of ∼1000 AU. Methods. We have carried out high-angular resolution (1. ′′ 4) observations in the continuum at 3.1mm and in the N 2 H + 1→0, CH 3 CN 5 k →4 k and 13 CS 2→1 lines using the Plateau de Bure Interferometer (PdBI). In addition, we have merged t...

We detect HCN J=5-4 emission from the ultraluminous quasar APM08279+5255 at z=3.911 using the IRAM Plateau de Bure interfer-ometer. This object is strongly gravitationally lensed, yet still thought to be one of the most intrinsically luminous objects in the Universe. The new data imply a line luminosity L ′ HCN (J=5−4) = 4.0 ± 0.5 × 10 10 K km s −1 pc 2. The ∼ 440 km s −1 full width half maximu...

Based on observations of the most abundant sulfur-bearing molecules (H 2 S, CS, NS, SO, H 2 CS, OCS, and SO 2) carried out with the IRAM 30m telescope 1 and SEST 2 , we present the first analysis of the sulfur chemistry of an extragalac-tic source, the nuclear region of the starburst galaxy NGC 253. This is the first time that H 2 S and, tentatively, H 2 CS are detected towards the nucleus of a...

We present subarcsecond resolution dust continuum observations of the protostellar collapse candidate B335 made with the IRAM Plateau de Bure Interferometer at wavelengths of 1.2 and 3.0 mm. These observations probe to < 100 AU size scales and reveal a compact source component that we identify with a circumstellar disk. We analyze these data in concert with previous lower resolution interferome...

We report on the first attempts at searching for CO in red low surface brightness galaxies, and the first detection of molecular gas in a low surface brightness (µ B (0) obs > 23 mag arcsec −2) galaxy. Using the IRAM 30m telescope, CO(1-0) and CO(2-1) lines were searched for in four galaxies – P06-1, P05-5, C05-3, & C04-2. In three of the galaxies no CO was detected, to T M B ∼1.8mK (at the 3σ ...
