It is a blazar or BL Lac object, which is an active galactic nucleus with a jet that is shooting towards the Earth. In the ultra high energy gamma ray region of the spectrum, at energies above 0.1 Teraelectronvolts (TeV), it is the brightest object in the sky (1011 eV). The object has a redshift of z = 0.034.〔 The galaxy hosting the blazar was studied and catalogued by Benjamin Markarian in 1974. It was first determined to be a very high energy gamma ray emitter in 1996 by J. Quinn at the Whipple Observatory.〔 ==Galaxy== The elliptical galaxy is located in the constellation of Hercules at right ascension 16h 53.9m and declination +39° 45'. Its visible size appears to be 1.2 by 1 minute of arc.〔http://www.elisanet.fi/jere.kahanpaa/astro/scan/ugc/ugc10599.htm〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Markarian 501」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
