A Green Bank Telescope Search for Water Masers in Nearby Active Galactic Nuclei
J. A. Braatz, C. Henkel, L. J. Greenhill +2
Using the Green Bank Telescope, we have conducted a survey for 1.3 cm water maser emission toward the nuclei of nearby active galaxies, the most sensitive large survey for H2O mase…
Sulfur chemistry and isotopic ratios in the starburst galaxy NGC 253
S. Martín, J. Martín-Pintado, R. Mauersberger +2
Based on observations of the most abundant sulfur-bearing molecules (H2S, CS, NS, SO, H2CS, OCS, and SO2) carried out with the IRAM 30m telescope and SEST, we present the first ana…
The interstellar C18O/C17O ratio in the solar neighbourhood: The rho Oph cloud
J. G. A. Wouterloot, J. Brand, C. Henkel
Observations of up to ten carbon monoxide (CO and isotopomers) transitions are presented to study the interstellar C18O/C17O ratio towards 21 positions in the nearby (d~140pc) low-…
