Tdcosmo Xvii. New Time Delays in 22 Lensed Quasars From Optical Monitoring with the Eso-vst 2.6m and Mpg 2.2m Telescopes

Frédéric Courbin, Eric Gérard Guy Paic, Vivien François Bonvin, Aymeric Alexandre Galan, Cameron Alexander Campbell Lemon

We present new time delays, the main ingredient of time delay cosmography, for 22 lensed quasars resulting from high-cadence r-band monitoring on the 2.6 m ESO VLT Survey Telescope and Max-Planck-Gesellschaft 2.2 m telescope. Each lensed quasar was typical ...

VELOcities of CEpheids (VELOCE): I. High-precision radial velocities of Cepheids

Henryka Ewa Netzel, Saniya Khan, Vivien François Bonvin, Shreeya Sushil Shetye

We present the first data release of VELOcities of CEpheids (VELOCE), dedicated to measuring the high-precision radial velocities (RVs) of Galactic classical Cepheids (henceforth, Cepheids). The first data release (VELOCE DR1) comprises 18 225 RV measureme ...

Constraints on the Hubble constant from supernova Refsdal's reappearance

Vivien François Bonvin, Mathilde Jauzac, Martin Raoul Robert Millon, Anja Von der Linden

The gravitationally lensed supernova Refsdal appeared in multiple images produced through gravitational lensing by a massive foreground galaxy cluster. After the supernova appeared in 2014, lens models of the galaxy cluster predicted that an additional ima ...
