JWST lensed quasar dark matter survey I: Description and First Results
A. M. Nierenberg, R. E. Keeley, D. Sluse +18
The flux ratios of gravitationally lensed quasars provide a powerful probe of the nature of dark matter. Importantly, these ratios are sensitive to small-scale structure, irrespect…
Strong gravitational lensing as a probe of dark matter
S. Vegetti, S. Birrer, G. Despali +8
Dark matter structures within strong gravitational lens galaxies and along their line of sight leave a gravitational imprint on the multiple images of lensed sources. Strong gravit…
TDCOSMO XIV: Practical Techniques for Estimating External Convergence of Strong Gravitational Lens Systems and Applications to the SDSS J0924+0219 System
Patrick Wells, Christopher D. Fassnacht, C. E. Rusu
Time-delay cosmography uses strong gravitational lensing of a time-variable source to infer the Hubble Constant. The measurement is independent from both traditional distance ladde…
Probing sub-galactic mass structure with the power spectrum of surface-brightness anomalies in high-resolution observations of galaxy-galaxy strong gravitational lenses. I. Power-spectrum measurement and feasibility study
D. Bayer, L. V. E. Koopmans, J. P. McKean +4
While the direct detection of the dark-matter particle remains very challenging, the nature of dark matter could be possibly constrained by comparing the observed abundance and pro…
TDCOSMO. XII. Improved Hubble constant measurement from lensing time delays using spatially resolved stellar kinematics of the lens galaxy
Anowar J. Shajib, Pritom Mozumdar, Geoff C. -F. Chen +12
Strong-lensing time delays enable measurement of the Hubble constant () independently of other traditional methods. The main limitation to the precision of time-delay cosmog…
