1989ApJ...344..200S CO EMISSION FROM NGC 5195 LESLIE I. SAGE Astrophysics Research Center, Department of Physics, New Mexico Institute of Mining and Technology Received 1988 August 9; accepted 1989 February 10 ABSTRACT Observations of CO J = 1 -> 0 emission from six points in NGC 5195 are reported. CO was detected at five of the six points and is clearly extended to the south (toward NGC 5194). Previous observations of NGC 5195 have failed to detect CO, probably because the line widths are much greater than expected. Some spectra show evidence for two distinct emitting regions, giving rise to a narrow and wide component to the CO line. The narrow component arises from an overlying spiral arm of NGC 5194 and the wide component arises from molecular gas inside NGC 5195. Molecular gas exists at least 2.5 kpc from the center of NGC 5195, unlike other S0 galaxies observed by Sage and Wrobel. The CO emission from the overlying spiral arm of NGC 5194 arises from a region 14 kpc (0.97R_25_) from the galaxian center. Most spiral galaxies have observable CO emission only from the inner half of the optical radius (0.5R_25_). Subject headings: galaxies: individual (NGC 5195) - galaxies: interstellar matter - galaxies: molecules
