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…
An analytic surface density profile for CDM halos and gravitational lensing studies
Alexandres Lazar, James S. Bullock, Anna Nierenberg +2
We introduce an analytic surface density profile for dark matter halos that accurately reproduces the structure of simulated halos of mass , makin…
LensWatch: I. Resolved HST Observations and Constraints on the Strongly-Lensed Type Ia Supernova 2022qmx ("SN Zwicky")
J. D. R. Pierel, N. Arendse, S. Ertl +39
Supernovae (SNe) that have been multiply-imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools…
Out of sight, out of mind? The impact of correlated clustering in substructure lensing
Alexandres Lazar, James S. Bullock, Michael Boylan-Kolchin +3
A promising route for revealing the existence of dark matter structures on mass scales smaller than the faintest galaxies is through their effect on strong gravitational lenses. We…
The effect of dark matter-dark radiation interactions on halo abundance -- a Press-Schechter approach
Omid Sameie, Andrew J. Benson, Laura V. Sales +3
We study halo mass functions with the Press-Schechter formalism for interacting dark matter models, where matter power spectra are damped due to dark acoustic oscillations in the e…
Beyond subhalos: Probing the collective effect of the Universe's small-scale structure with gravitational lensing
Francis-Yan Cyr-Racine, Charles R. Keeton, Leonidas A. Moustakas
Gravitational lensing has emerged as a powerful probe of the matter distribution on subgalactic scales, which itself may contain important clues about the fundamental origins and p…
