摘要: Galactic nuclei are well known sources of OH and H2O maser emission. It appears that intense star formation in ultra-luminous infrared galaxies drives most sources. In contrast, nuclear activity to drive When emission originates accretion disk structures, constrained geometry dynamics enable robust interpretation spectroscopic imaging data. The principal science includes study AGN at parsec sub-parsec radii measurement geometric distances the Hubble Flow. New high accuracy estimates constant, "Ho," obtained from may new substantively improved constraints on fundamental cosmological parameters (e.g., dark energy).
