Spectroscopy of astrophysical maser lines with the Torun 32m radio telescope

摘要

Studies of molecular emission amplified in the natural maser process are essential to explore various astrophysical phenomena. The natural maser emission is so strong that it can be observed in several astrophysical environments using medium-sized telescopes. Here we report an overview of equipments of the 32m radio telescope suitable for spectral observations. A summary of the main results of the Galaxy plane survey in the 6.7 GHz methanol maser line is given and the latest finding of the periodic and alternate flares of the methanol and water vapor masers in a high-mass protostar is highlighted.
