Microlensing study including proper motion of stellar lens objects

Autor: YONEHARA, Atsunori

Publikováno v: 京都産業大学総合学術研究所所報. 15:113-124

クェーサーマイクロレンズ現象は、背景クェーサーと前方銀河内の恒星の相対運動によって引き起こされる。その際、恒星の固有運動を考慮することで期待される、マイクロレンズ現象�

MACRO lens toward the Galactic Center: Secular component of apparent proper motion of QSOs induced by gravitational lens of the galaxy

Autor: Onishi, Koji, Hosokawa, Mizuhiko, Fukushima, Toshio

Publikováno v: VLBI技術による宇宙研究シンポジウム = Symposium on Space Research with VLBI Technology. :4-10

The observed position of QSOs may vary due to the gravitational deflection by foreground objects. This effect is eminent in the direction of the Galactic Center. To measure the distance to the Galactic Center with the relative error of a few percent,
