Dark Matter Lensing
Cameras 2019 - Dark Matter Lensing, What is gravitational lensing? | cfhtlens, Gravitational lensing is useful to cosmologists because it is directly sensitive to the amount and distribution of dark matter. this is because the amount of light bending is sensitive only to the strength of the gravitational field it passes through*, which is mostly generated by the mass of the dark matter in the universe.. Dark matter - wikipedia, Dark matter is a hypothetical form of matter that is thought to account for approximately 85% of the matter in the universe, and about a quarter of its total energy density.the majority of dark matter is thought to be non-baryonic in nature, possibly being composed of some as-yet undiscovered subatomic particles.its presence is implied in a variety of astrophysical observations, including .. What is dark matter? searching with gravity, lensing, The pink represents the hot gas (by far most of the mass of the luminous matter), and the blue is a visualization of the dark matter based on gravitational lensing measurements..

astrophysicist alexie leauthaud investigates dark matter with gravitational lensing. see her talk with reiko nakajima at lawrence berkeley lab here: evidence for dark matter - gravitational lensing for free videos and study notes, as well as online revision courses, go to studynova.
[1001.1739] the dark matter of gravitational lensing, Abstract: we review progress in understanding dark matter by astrophysics, and particularly via the effect of gravitational lensing. evidence from many different directions now all imply that five sixths of the material content of the universe is in this mysterious form, separate from and beyond the ordinary "baryonic" particles in the standard model of particle physics..
