Using gravitational lensing to measure the Hubble Constant
The EPFL Laboratory of Astrophysics (LASTRO) is involved in an international research project to measure the Hubble constant, also known as the expansion rate of the Universe. The methods rely on gravitational lenses and the measurement of time delays between multiple images of quasars that are billions of light years away. One such recent image (…)
