Abstract :
Limitations imposed by the atmosphere at terahertz (THz) frequencies have restricted researchers from retrieving crucial information regarding astronomical sources. With the availability of sensitive detectors and new generation of telescopes, the terahertz instrumentation has improved drastically over the past two decades. High spectral resolution information retrieved from star forming molecular system is very essential in understanding the model of evolution process of stars and galaxies. In this paper, we will present the development of a submillimeter wave (300-3000 GHz) receiver system to study interstellar molecular clouds dynamics and chemistry.
