Berkeley, CA — Weak gravitational lensing is a uniquely promising way to learn how much dark matter there is in the Universe and how its distribution has evolved since the distant past. New work by a ...
Think you can figure out a way to unlock one of the biggest secrets of the universe? The recently launched third Gravitational Lensing Accuracy Testing challenge (GREAT3) is giving researchers the ...
A new study led by European scientists presents the most comprehensive analysis of data from the most ambitious survey ever undertaken by the NASA/ESA Hubble Space Telescope. These researchers have, ...
A cosmologist has extended the relationship between the x-ray luminosity and the mass of galaxy clusters as measured by gravitational lensing, improving the reliability of mass measurements of much ...
Does the universe behave the same way everywhere? Weak gravitational lensing could provide an answer
A study published in the Journal of Cosmology and Astroparticle Physics (JCAP) presents a methodology to test the assumption of cosmic homogeneity and isotropy, known as the Cosmological Principle, by ...
Gravitational lensing - the phenomenon in which diverging light rays from a source are refocused due to the warping of space by a massive object - has in recent years evolved from a beautiful test of ...
