Gravitational lens of 2 galaxies in front of a quasar

Using gravitational lensing to measure the Hubble Constant

Dark Energy, Dark Matter, Galaxy evolution, Gravitational lensing

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 is of a lensed quasar known simply as 2M1310-1714. Martin Millon, a PhD student at LASTRO is here to explain more.

Researchers at EPFL’s Laboratory of Astrophysics are part of an international consortium of scientists that have designed a new method of conducting an exhaustive view of the oldest and most metal-poor stars in the Milky-Way The science of observational cosmology involves the study of the structure and origin of the Universe. It can be conducted (…)
