COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses: First results and status report |
The Hubble constant, related to the age of the Universe, can be measured in a very direct and independant way through the measurement of the time delays in gravitationally lensed quasars. COSMOGRAIL is a whole-sky photometric monitoring of such gravitationally lensed quasars aimed at measuring up to 20 new time delays within the next 3 years, with an accuracy of a few percents. The first results of this international collaboration are presented, including new light curves and time delays, as well as deep HST and VLT follow-up observations. |
