Spectrum(GPS)電波源について、VSOPとVLBAによる多周波でのサーベイ観測を行った結果を報告する。電波銀河型のGPSではスペクトルのピーク周波数が2つの電波ローブでほぼ同じであるのに対してクェーサー型のGPSでは有意に異なることを発見し、低周波カットオフの原因が低温・高密度プラズマによる自由-自由吸収で、かつ電波銀河とクェーサーとではジェットの視線角が異なるということが明らかになった。さらに、クェーサー型GPSにおける高周波側でのスペクトル指数は、電波銀河型のそれよりも大きい、ということがわかった。クェーサー型GPSで見られる平坦なスペクトルを示す成分は、中心核近傍のジェットがドップラー増幅を受けた成分、あるいは中心核そのものと考えられる。一方、電波銀河型GPSではこのような平坦なスペクトルの成分は見られないか弱い。これは、電波銀河型GPSの中心核成分は強い自由-自由吸収を受けているということを示している。","subitem_description_type":"Abstract"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
