Discovery of MgS and NaS in the Interstellar Medium and Tentative Detection of CaO

We report the first detection of the metal-bearing molecules sodium sulfide and magnesium sulfide and the tentative detection of calcium monoxide in the interstellar medium toward the Galactic center molecular cloud G+0.693-0.027. The derived column densities are (5.0 ± 1.1) × 10 ^10 cm ^−2 , (6.0 ±...
