Dense gas in nearby galaxies XIII. CO submillimeter line emission from the starburst galaxy M82
R. Q. Mao, C. Henkel, A. Schulz +5
12CO 1-0,2-1,4-3,7-6, and 13CO 1-0, 2-1, and 3-2 line was mapped with angular resolutions of 13" - 22" toward the nuclear region of starburst galaxy M82. The difference of lobe spa…
Molecular gas in the Galactic center region III. Probing shocks in molecular cores
S. Huettemeister, G. Dahmen, R. Mauersberger +3
Multiline observations of C18O and SiO isotopomers toward 33 molecular peaks in the Galactic center region, taken at the SEST, JCMT and HHT telescopes, are presented. The C18O pres…
Dense gas in nearby galaxies XI. H_2CO and CH_3OH: Molecular abundances and physical conditions
S. Huettemeister, R. Mauersberger, C. Henkel
Multilevel observations of formaldehyde (H_2CO) and methanol (CH_3OH) toward the nearby spiral galaxies NGC 253, Maffei 2, IC 342, M 82 and NGC 6946 are presented. H_2CO was detect…
Interstellar S: a probe of s-process nucleosynthesis
R. Mauersberger, C. Henkel, N. Langer +1
The first detection of a S-bearing molecule in interstellar space is reported. The = and transitions of CS have been observed toward eight Galactic mole…
Molecular abundances in the Magellanic Clouds II. Deuterated species in the LMC
Y. -N. Chin, C. Henkel, T. J. Millar +2
The first definite discoveries of extragalactic deuterium are reported. DCO has been detected in three and DCN has been measured in one star-forming region of the Large Magella…
