Mass-to-light ratio of binary galaxies

We report on the mass-to-light ratio determination based on a newly selected binary galaxy sample, which includes a large number of pairs whose separations exceed a few hundred...本研究报道了基于新筛选得到的双星系样本（binary galaxy sample）开展的质光比（mass-to-light ratio）测定工作，该样本涵盖大量间距超过数百的双星系对……
