Using the IRAM interferometer, we have observed the nearby starburst galaxy M 82 with a 4. ′′2 resolution (' 70 pc) in the 1→0 line of 13CO and in the λ 2.6-mm continuum. The spatial distribution of the 13CO line shows the same gross features as the 12CO(1→0) map of Shen & Lo (1995), namely two lobes and a compact central source, though with different relative intensities. The lobes are more co...

Thermally sprayed coatings are intrinsically associated with residual stresses in the deposits. These stresses are varied in nature and magnitude, and have a pronounced effect on the mechanical behavior of the system. In the current study, WC-12Co coatings were deposited using HVOF thermal spraying. The sin2ψ method was used to evaluate the through thickness residual stress by means ...

We present a study of molecular outflows using six lines (including 12CO/13CO/C18O/HCO+(J = 1-0) and SiO/CS(J 2-1)) toward nine nearby high-mass star-forming regions with accurate known distances. This work is based on the high-sensitivity observations obtained 14-m millimeter telescope Purple Mountain Observatory Delingha (PMODLH) observatory. The detection rate 12CO, 13CO, HCO+, CS) 100\%.

We report 12CO(J =3–2) observations of 15 nearby elliptical galaxies carried out with the ASTE telescope. Thirteen were selected without regard to the presence of other tracers of cold interstellar matter. CO emission was detected from three of the galaxies, two of which are undetected by IRAS at 100 microns, suggesting that cold ISM may be present in more ellipticals than previously thought. T...

We have carried out 12CO J=2–1 line observations of the supernova remnant (SNR) HB 21 in order to search for evidence of interaction with molecular clouds. We mapped the eastern half (80 × 110) of the SNR almost completely. Molecular gas appears to be distributed mainly along the boundary of the SNR, but the overall distribution has little correlation either with the distortion of the SNR bound...
