A study of the infrared characteristics of host IRAS sources with OH megamasers.
ZHI-YAO Y.
Abstract (from CDS):
The infrared properties of the host IRAS sources with OH megamasers are also studied. The most striking features are the anticorrelation of S(12µm)/S(25µm) versus S(60µm)/S(100µm) and the correlation of S(12µm)/S(25µm) versus S(25µm)/S(60µm). They are consistent with Henkel, Wouterlooy & Bally's finding that S(12µm)/S(25µm) is anticorrelated with S(60µm)/S(100µm), but are the opposite of Henkel et al.'s result that S(12µm)/S(25µm) is correlated with S(25µm)/S(60µm). This is an interesting difference. Our colour-colour plots suggest that the peak of the infrared spectra of our sample of OH sources is at a longer wavelength than the peak in the sample of Henkel et al. This suggests that infrared radiation from our sample is dominated by emission from material at greater separations from the central source.
