科學家相信，中型黑洞匿藏在許多我們鄰近的星系中，向四周發射超強射線，與超重黑洞不同的是，它們並非位於星系中心，而是散布在銀盤上。More recently, dr. rosanne di stefano also from the harvard - smithsonian centre for astrophysics and i used the chandra x - ray observatory to detect objects dubbed " quasisoft " x - ray sources in nearby galaxies because of their low temperatures, which are at most four million degrees celsius. that is well below the temperatures expected for " hard " x - ray sources such as neutron stars or stellar mass black holes - which run between 10 million and 100 million degrees celsius - and still hotter than " soft " x - ray sources like white dwarfs
最近羅珊迪史提芬路博士她亦來自哈佛大學史密森天體物理中心和筆者利用錢德拉射線天文臺在鄰近星系偵測到一種奇怪的-射線源，我們稱之為類軟射線源，因為它們的溫度最高只有攝氏400萬度，遠低於一般硬射線源，例如中子星和恆星型黑洞溫度介乎攝氏1千萬至1億度，卻又比軟射線源例如白矮星為高。The two formulas are nearly the same for nearby galaxies but diverge for distant galaxies

如果我們在沒有鄰近星系團的情形下計數遙遠的星系團，則可得出第一因子。There are two major errors. the first one is the error occurred in measuring v. although astronomers can locate v of individual galaxy accurately through the spectrum and the doppler s effect, owing to the gravitational pull exerted from neighbouring galaxies and clusters of galaxies, v is not wholly determined by the expansion of the universe
有兩個主要的誤差：第一個是測量退行速度的誤差，雖然天文學家利用光譜及多普勒效應，已經很準確地找到個別星系的退行速度，但由於與鄰近星系及星系團的引力作用，這個退行速度便不完全是因宇宙膨分享友人
