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, . However, it has been proposed that the combination of microlensi…

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…

A Microlensing Accretion Disk Size Measurement in the Lensed Quasar WFI 2026-4536

Matthew A. Cornachione, Christopher W. Morgan, Martin Millon +4

We use thirteen seasons of R-band photometry from the 1.2m Leonard Euler Swiss Telescope at La Silla to examine microlensing variability in the quadruply-imaged lensed quasar WFI 2…
