Abstract The observations of the par improved spectroscopy and the molecular clouds at the galactic center are reported. The results show: the spatial distributions of C(II) microns and molecular line radiation and of the thermal radio continuum emission in the arched filaments of the radio arc are similar; about 2 x 10 4 of the solar mass, or 10 percent of the total gas mass in the radio.

As a result of redshifting, they are most directly selected through their emission in the submillimeter (submm) or mm wavebands, typically in the atmospheric windows around or µm, and.
Research of the Infrared and Submillimeter Group is focused on the fields of evolution of galaxies and galactic nuclei, including the center of our own Galaxy and starburst phenomena, as well as studies of the dense interstellar medium in star- and planet forming regions.
The bulk of the luminosity of these obscured galaxies is emitted in the rest-frame far-infrared waveband. As a result of redshifting, they are most directly selected through their emission in the submillimeter (submm) or mm wavebands, typically in the atmospheric windows around or μm, and so are termed submm galaxies (SMGs).
