A RUDN University physicist has developed a formula for evaluation of the effect of dark matter on the size of the shadow of a black hole. It turned out that the effect would be noticeable only if the concentration of this hypothetical form of matter around black holes in the centers of galaxies is abnormally high. If it is not the case, then it is unlikely that dark matter could be detected using the shadow of a black hole. The work was published in the journal Physics Letters B: Nuclear, Elementary Particle and High Energy Physics.
