Gaia GraL X.: The GraL catalogue of gravitationally lensed quasars Matched with \textit{Gaia} data, redshifts, and time delays

C. Ducourant, R. Teixeira, P. H. Vale-Cunha +25

Determining the Hubble constant tension requires alternative strategies, and multiply imaged quasars, with their intermediate redshifts, can potentially be used in this regard. We…

Gaia GraL: Gaia gravitational lens systems IX. Using XGBoost to explore the Gaia Focused Product Release GravLens catalogue

Quentin Petit, Christine Ducourant, Eric Slezak +21

Aims. Quasar strong gravitational lenses are important tools for putting constraints on the dark matter distribution, dark energy contribution, and the Hubble-Lemaitre parameter. W…

Gaia GraL: Gaia DR2 Gravitational Lens Systems. VIII. A radio census of lensed systems

Dougal Dobie, Dominique Sluse, Adam Deller +26

We present radio observations of 24 confirmed and candidate strongly lensed quasars identified by the Gaia Gravitational Lenses (GraL) working group. We detect radio emission from…

Shape, alignment, and mass distribution of baryonic and dark-matter halos in one EAGLE simulation

Q. Petit, C. Ducourant, E. Slezak +2

Accurate knowledge of the morphology of halos and its evolution are key constraints on the galaxy formation model as well as a determinant parameter of the strong-lensing phenomeno…

Gaia GraL: Gaia DR2 Gravitational Lens Systems. VII. XMM-Newton Observations of Lensed Quasars

Thomas Connor, Daniel Stern, Alberto Krone-Martins +23

We present XMM-Newton X-ray observations of nine confirmed lensed quasars at identified by the Gaia Gravitational Lens program. Eight systems are strongly…
