English Dictionary

green pea galaxy

名詞

(astronomy) A type of galaxy, found in the local universe, that are active, undergoing high rates of star formation, which provides a green tinge, and are compact, visually appearing akin to peas. These active galaxies have strong oxygen emission lines and no active galactic nucleus (“AGN”), similar to small galaxies in the distant early universe, but unlike those in the nearby contemporary universe.

日本語の意味

近傍宇宙に存在する、アクティブで急速な星形成活動を示す銀河の一種。酸素の強い放射線線が観測され、活性銀河核（AGN）は存在しない。コンパクトで、豆（ピー）のような外観と緑がかった色調を特徴とする。

The astronomers celebrated when they confirmed that the compact object was indeed a green pea galaxy, because its intense star formation and strong oxygen emission lines mirror conditions in early-universe dwarfs.

天文学者たちは、そのコンパクトな天体が緑色がかったエンドウ豆状の小型星形成銀河であることを確認すると歓声を上げた。激しい星形成と強い酸素の輝線が初期宇宙の矮小銀河の状況を反映しているからだ。
