In my PhD-project I am studying the X-Ray characteristics of H2O Megamaser in active galactic nuclei(AGN) based on a comparison of one pure maser-sample and a comparative group of objects which show no maser activity.
Watermaser galaxies are a subclass of AGN and belong to the brightest sources in the Universe. They allow us to study a wide range of physical aspects refering to non-thermal emission and represent a significant improvement for measuring geometrical distances with high precision. This yields to a determination of the Hubble constant H_0 with accuracy better then 3% which would provide powerful constrains on cosmological models (e.g. on the equation of state of dark energy). Therefore maser play a keyrole in modern cosmology.
