Outline of Final Research Achievements

In order to reveal the structure of the molecular tori, which have be proposed as a key element in the unified scheme of Active Galactic Nuclei (AGNs), we observed the 4.7 micron carbon-monoxide (CO) ro-vibrational absorption band spectra toward several AGNs with the Japanese infrared astronomical satellite AKARI. We detected warm (200-500 K) gas with large column densities and attributed this component to the molecular tori around AGNs. We suggested that the molecular clouds in the tori were heated by X-ray radiation from the central engine of AGNs.
For the future observations of the CO absorption toward high-z AGNs from space borne observatories, we developed a immersion grating for high-resolution spectroscopy in the mid-infrared. We selected CdZnTe as an optimum material for our study, and demonstrated the performance of the immersion grating made of CdZnTe at room temperature.
