JWST lensed quasar dark matter survey V: Hints of self-interacting dark matter from 29 quadruply imaged quasars

D. Gilman, A. M. Nierenberg, J. Gurian +21

Theories of self-interacting dark matter (SIDM) predict the eventual core collapse of dark matter halos, a process that transforms these structures into extremely efficient gravita…

TDCOSMO XXVIII. The Hubble constant from the quadruply lensed quasar J15373010 with precise time delays

A. Galan, A. G. Schweinfurth, S. H. Suyu +21

We present the first measurement of the Hubble constant () from the quadruply-lensed quasar J15373010, which has optically-measured time delays at precision. We…

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…

VAR-PZnn: A machine-learning framework for AGN photometric redshifts using color and variability-based features

S. Satheesh-Sheeba, P. Sánchez-Sáez, R. J. Assef +39

Photometric redshift estimation for active galactic nuclei (AGNs) remains a fundamental challenge for current and upcoming large-scale photometric surveys. Traditional spectral ene…

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…

Strong Lensing Tomography: Double and pseudo multi-source plane strong gravitational lensing to constrain dark energy

Paras Sharma, Simon Birrer, Narayan Khadka +12

Tomographic measurements of gravitational lensing with different lens and source redshift distributions contain crucial information about the universe's relative expansion rate, an…
