Dark matter, an invisible and unknown type of material, is postulated to hold clusters together. X-ray observations have the unique ability to determine the ratio of the mass of the hot gas and the mass of the dark matter in a cluster. The observed values of the gas fraction depend on the assumed distance to the cluster. pdboyer Sat, 06 Nov 2010 19:41:34 GMT http://www.nytimes.com/2009/11/15/books/review/Martin-t.html?_r=1 ma_martin Thu, 07 Jan 2010 14:37:20 GMT http://www.npr.org/templates/story/story.php?storyId=120141581 ma_martin Thu, 07 Jan 2010 14:35:59 GMT http://www.lavanguardia.es/cultura/noticias/20091126/53831349127/paul-auster-tal-vez-la-verdad-es-invisible.html ma_martin Thu, 07 Jan 2010 14:35:40 GMT http://www.independent.co.uk/arts-entertainment/books/reviews/invisible-by-paul-auster-1811036.html ma_martin Thu, 07 Jan 2010 14:32:49 GMT http://www.elplacerdelalectura.com/2009/12/invisible-paul-auster.html ma_martin Thu, 07 Jan 2010 14:32:28 GMT http://www.guardian.co.uk/books/2009/nov/14/invisible-paul-auster-book-review ma_martin Thu, 07 Jan 2010 14:31:27 GMT http://entertainment.timesonline.co.uk/tol/arts_and_entertainment/the_tls/article6906408.ece ma_martin Thu, 07 Jan 2010 14:30:57 GMT
