    Odds that the stellar–LX correlation is positive as a function of the minimum imposed stellar mass scatter. The blue dashed and green dotted lines shows the odds for stellar mass proxies of LK and Î», respectively. The red solid line shows the odds of having a positive correlation coefficient for both stellar mass proxies and LX. The light gray, gray, and dark gray shaded regions show respectively the regions with <5%, <1%, and <0.5% odds of having a positive or zero correlation

    A method of weighing the quantities of matter in galaxy clusters – the largest objects in our universe – has shown a balance between the amounts of hot gas, stars and other materials...
