Programme)とVLBA(VLBI Array)を用いて1.6-15.4GHzの5周波で18天体のGHz-Peaked Spectrum(GPS)電波源のサーベイ観測を行なった結果を報告する。GPS電波源はGHz帯にピークを持つ連続スペクトルを示すAGN(Active Galactic Nuclei)に付随する電波源で、低周波側のスペクトルカットオフは自由-自由吸収あるいはシンクロトロン自己吸収によるものと考えられている。多周波VLBI観測によって、吸収の空間分布を詳細に調べることができた。その結果、Type-1GPS電波源(クェーサー)とType-2GPS電波源(Sy2および電波銀河)とで吸収の分布に違いが見られた。Type-2では遠ざかる側のジェットで吸収が深く、トーラス状に分布したプラズマによる吸収を示している。一方Type-1では中心核とジェットの先端で吸収が深く、シンクロトロン自己吸収を示唆している。","subitem_description_type":"Abstract"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
