低核密度球狀星團NGC6144以及E3的X光與可見光波段之研究
碩士 === 國立清華大學 === 天文研究所 === 97 === We report on the Chandra X-ray Observatory and Hubble Space Telescope observation of two low core density globular clusters, NGC6144 and E3. Within the half-mass radius and at a detection limit of L_X = 1.7 × 10^30 ergs/s , we found 6 X-ray sources in NGC6144, of w...
