Large number of dark matter peaks found using gravitational lensing

A number of studies have shown that dark matter is the principle mass component of the universe making up about 80% of the mass budget. The most direct technique to reveal the dark matter distribution is by using the gravitational lensing technique. Indeed, following Einstein's theory of gravitation, we know that a mass concentration will deform locally the space-time and the observed shapes of distant galaxies seen through the such concentration will be deflected and distorted. By measuring the...
