Detection of C5N- and vibrationally excited C6H in IRC +10216
J. Cernicharo, M. Guélin, M. Agúndez +2
We report the detection in the envelope of the C-rich star IRC +10216 of four series of lines with harmonically related frequencies: B1389, B1390, B1394 and B1401. The four series…
Search for anions in molecular sources: C4H- detection in L1527
M. Agundez, J. Cernicharo, M. Guelin +3
We present the results of a search for the negative ion C4H- in various dark clouds, low mass star-forming regions and photon-dominated regions (PDRs). We have also searched for C6…
Detection of HNC and tentative detection of CN at z=3.9
M. Guelin, P. Salome, R. Neri +8
Molecular line emission from high-redshift galaxies holds great promise for the study of galaxy formation and evolution. The weak signals can only be detected with the largest mm-w…
A New Probe of Dense Gas at High Redshift: Detection of HCO+(5-4) Line Emission in APM 08279+5255
S. Garcia-Burillo, J. Gracia-Carpio, M. Guelin +6
We report the detection of HCO+(5-4) emission from the Broad Absorption Line (BAL) quasar APM08279+5255 at z=3.911 based on observations conducted at the IRAM Plateau de Bure inter…
Detection of the linear radical HC4N in IRC+10216
J. Cernicharo, M. Guelin, J. R. Pardo
We report the detection of the linear radical HC4N in the C-rich envelope of IRC+10216. After HCCN, HC4N is the second member of the allenic chain family HC_(2n)N observed in space…
