Overluminous HNC Line Emission in Arp220, NGC4418 and Mrk231 - Global IR Pumping or XDRs?
S. Aalto, M. Spaans, M. C. Wiedner +1
We find that the HNC J=3-2 emission is brighter than the HCN 3-2 emission by factors of 1.5 to 2.3 in the ultraluminous mergers Arp220 and Mrk231 and the luminous IR galaxy NGC4418…
First observations with CONDOR, a 1.5 THz heterodyne receiver
M. C. Wiedner, G. Wieching, F. Bielau +15
The THz atmospheric windows centered at roughly 1.3 and 1.5~THz, contain numerous spectral lines of astronomical importance, including three high-J CO lines, the N+ line at 205 mic…
Probable detection of H2D+ in the starless core Barnard 68
M. R. Hogerheijde, P. Caselli, M. Emprechtinger +8
The presence of H2D+ in dense cloud cores underlies ion-molecule reactions that strongly enhance the deuterium fractionation of many molecular species. We determine the H2D+ abunda…
The Distribution of Ortho-H_2D+(1_1,0 - 1_1,1) in L1544: Tracing the Deuteration Factory in Prestellar Cores
C. Vastel, P. Caselli, C. Ceccarelli +5
Prestellar cores are unique laboratories for studies of the chemical and physical conditions preceding star formation. We observed the prestellar core L1544 in the fundamental tran…
