TDCOSMO XVII. New time delays in 22 lensed quasars from optical monitoring with the ESO-VST 2.6m and MPG 2.2m telescopes

Frédéric Dux, Martin Millon, Aymeric Galan +29

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…

Nine lensed quasars and quasar pairs discovered through spatially-extended variability in Pan-STARRS

Frédéric Dux, Cameron Lemon, Frédéric Courbin +7

We present the proof-of-concept of a method to find strongly lensed quasars using their spatially-extended photometric variability through difference imaging in cadenced imaging su…

RVSPY -- Radial Velocity Survey for Planets around Young Stars. Target characterization and high-cadence survey

O. Zakhozhay, R. Launhardt, A. Mueller +15

We introduce our Radial Velocity Survey for Planets around Young stars (RVSPY), characterise our target stars, and search for substellar companions at orbital separations smaller t…

Bias-free model fitting of correlated data in interferometry

Régis Lachaume

In optical and infrared long-baseline interferometry, data often display significant correlated errors because of uncertain multiplicative factors such as the instrumental transfer…
