Measuring accretion disk sizes of lensed quasars with microlensing time delay in multi-band light curves

J. H. H. Chan, K. Rojas, M. Millon +3

Time-delay cosmography in strongly lensed quasars offer an independent way of measuring the Hubble constant, H0​. However, it has been proposed that the combination of microlensi…

TDCOSMO II: 6 new time delays in lensed quasars from high-cadence monitoring at the MPIA 2.2m telescope

M. Millon, F. Courbin, V. Bonvin +25

We present six new time-delay measurements obtained from Rc​-band monitoring data acquired at the Max Planck Institute for Astrophysics (MPIA) 2.2 m telescope at La Silla observa…

COSMOGRAIL XIX: Time delays in 18 strongly lensed quasars from 15 years of optical monitoring

M. Millon, F. Courbin, V. Bonvin +16

We present the results of 15 years of monitoring lensed quasars, which was conducted by the COSMOGRAIL programme at the Leonhard Euler 1.2m Swiss Telescope. The decade-long light c…
