Gravitational Lensing with Data from the Euclid Space Mission — The biggest mysteries in physics are the accelerated expansion of the Universe caused by dark energy, and dark matter, which forms the structure in the Universe, including our own Milky Way galaxy. Despite accounting for most of the matter-energy content of the Universe, their properties are only poorly known. The Euclid space mission will measure their properties by using the distortion of shapes of distant galaxies by gravitating matter, known as gravitational lensing. This proposal is to study the expected gravitational lensing effect around galaxies using simulations and measure it in the first release of Euclid data.
