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…
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 -band monitoring data acquired at the Max Planck Institute for Astrophysics (MPIA) 2.2 m telescope at La Silla observa…
Time Delay Lens Modelling Challenge
X. Ding, T. Treu, S. Birrer +26
In recent years, breakthroughs in methods and data have enabled gravitational time delays to emerge as a very powerful tool to measure the Hubble constant . However, published…
H0LiCOW XI. A weak lensing measurement of the external convergence in the field of the lensed quasar B1608+656 using HST and Subaru deep imaging
O. Tihhonova, F. Courbin, D. Harvey +11
We investigate the environment and line of sight of the H0LiCOW lens B1608+656 using Subaru Suprime-Cam and the Hubble Space Telescope (HST) to perform a weak lensing analysis. We…
HOLISMOKES -- I. Highly Optimised Lensing Investigations of Supernovae, Microlensing Objects, and Kinematics of Ellipticals and Spirals
S. H. Suyu, S. Huber, R. Cañameras +10
We present the HOLISMOKES programme on strong gravitational lensing of supernovae as a probe of supernova (SN) physics and cosmology. We investigate the effects of microlensing on…
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…
