Lisa Randall

Lisa Randall (born June 18, 1962) is an American theoretical physicist and an expert on particle physics and cosmology. She is the Frank B. Baird, Jr. Professor of Science on the physics faculty of Harvard University.[1] Her research includes elementary particles and fundamental forces and she has developed and studied a wide variety of models, the most recent involving extra dimensions of space. She has advanced the understanding and testing of the Standard Model, supersymmetry, possible solutions to the hierarchy problem concerning the relative weakness of gravity, cosmology of extra dimensions, baryogenesis, cosmological inflation, and dark matter.[2] Her best-known contribution is the Randall–Sundrum model, first published in 1999 with Raman Sundrum.[3]

Abell 2142 - most massive object in the Universe?

Image
Abell 2142, or A2142 , is a huge, X-ray luminous galaxy cluster in the constellation Corona Borealis . It is the result of a still ongoing merger between two galaxy clusters. The combined cluster is six million light years across, contains hundreds of galaxies and enough gas to make a thousand more. It is "one of the most massive objects in the universe."

Schiaparelli (SkiAppUhRelEE)

Image
Schiaparelli EDM lander [skjapaˈɾɛlːi] was the Entry, Descent and Landing Demonstrator Module (EDM) of the ExoMars programme—a joint mission of the European Space Agency (ESA) and the Russian space agency Roscosmos . [4] It was built in Italy and was intended to test technology for future soft landings on the surface of Mars . [5] It also had a limited but focused science payload that would have measured atmospheric electricity on Mars and local meteorological conditions.

Great Attractor

Image
The Great Attractor is a gravitational anomaly in intergalactic space within the vicinity of the Hydra-Centaurus Supercluster at the centre of the Laniakea Supercluster that reveals the existence of a localised concentration of mass tens of thousands of times more massive than the Milky Way . This mass is observable by its effect on the motion of galaxies and their associated clusters over a region hundreds of millions of light-years across. The Great Attractor is moving towards the Shapley Supercluster . [1] https://en.wikipedia.org/wiki/Great_Attractor   Portal
