Outline of Final Research Achievements

In order to reveal the creation, acceleration, and collimation mechanism of jets ejected from the vicinity of super massive black hole at the center of active galactic nuclei, it is important to execute direct imaging of magnetic field structure around the base of the jets at millimeter wavelengths, where the jets are optically thinner. To achieve this, it is necessary to monitor the jet base using very long baseline radio interferometer (VLBI) with the highest spatial resolution.
In this program, the receivers of the two radio telescopes of the NAOJ VERA were developed to enable simultaneous dual polarization reception at 43 GHz (7 mm). Furthermore, by combining the two VERA telescopes and three telescopes in Korea, we have organized a VLBI network capable of polarization observation based on international collaboration. This is a definite step forward in VLBI monitoring of jets from super massive black hole.

Academic Significance and Societal Importance of the Research Achievements

巨大ブラックホール最近傍からのガスの噴出流であるジェットは銀河全体の明るさに比して桁違いの光度で輝き、宇宙における最もダイナミックなエネルギー現象である。その噴出メカニズムを捉えるのは、現代天文学の解決すべき問題の一つである。ジェットが生成されるブラックホールの周囲を取り巻く環境の研究は、ブラックホール自体の存在やその基本的な性質をより明確化すると考えられる。ブラックホールが、現在の宇宙の構造と共に、138億年の歴史の中でどのように作られてきたかを知ることは、人類共通の根源的な問題に直接アプローチすることにつながるといえよう。
