HST imaging, pipeline modeling, and time-delay predictions of 2 triply-imaged and 15 quadruply-imaged lensed quasars
William Sheu, Tommaso Treu, Adriano Agnello +10
The Hubble tension remains a significant challenge in modern cosmology, exhibiting a discrepancy between early-Universe cosmic microwave background measurements and local distance…
Constraining the Physical Properties of Quadruply Lensed Quasars using Optical-to-X-Ray Data
Kriti Kamal Gupta, Dominique Sluse, Maarten Baes +5
Gravitational lensing of luminous active galactic nuclei (AGN; or quasars) can be used as a natural telescope to zoom in on their inner structures. With more and more lensed AGN be…
First measurement of narrow-line flux ratios for a lensed quasar with JWST/NIRSpec IFS
Hadrien Paugnat, Tommaso Treu, Anna M. Nierenberg +3
Strong gravitational lensing is a powerful probe of dark matter (DM) structure on subgalactic scales: in particular, statistics of flux-ratio anomalies (discrepancies between mass…
The free-streaming length of dark matter from JWST observations of 28 strong gravitational lenses
D. Gilman, A. M. Nierenberg, T. Treu +24
The formation of gravitationally bound overdensities of dark matter (DM), or \textit{halos}, is a generic prediction of theories with particle DM. We present a measurement of halo…
JAXtronomy: A JAX port of lenstronomy
Alan Huang, Simon Birrer, Daniel Gilman +4
Gravitational lensing is a phenomenon where light bends around massive objects, resulting in distorted images seen by an observer. Studying gravitationally lensed systems provides…
