Description
We report the first ground-based detection of the water line p-H2O (211-202) at 752.033 GHz in three ULIRGs (IRAS 06035-7102, IRAS 17207-0014, and IRAS 09022-3615) with redshifts below 0.08. Utilizing the APEX SEPIA band-9 receiver, we achieve signal-to-noise ratios of 8-10 in all three galaxies, marking the first detection of this line in IRAS 06035-7102. The water line spectra are compared to mid-đœ CO and dust continuum data from previous ALMA observations. In the complex system IRAS 09022-3615, the water emission line profile exhibits a velocity offset compared to the ALMA CO(đœ = 4 â 3) emission. Conversely, for IRAS 17207-0014 and IRAS 06035-7102, the profiles of the water line and the CO lines show spectroscopic alignment. This pilot study illustrates the potential for direct ground-based high-frequency observations of this water line.
