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…

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…

Measurement of the minimum cold dark matter halo mass with strong gravitational lensing

A. M. Nierenberg, D. Gilman, T. Treu +19

We explore the lowest mass limit that can be placed on the halo mass function in CDM using 28 strong gravitational lenses. For this purpose, we study an extreme model in which the…

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…

Imagining the Alien: Human Projections and Cognitive Limitations

S. G. Djorgovski

Imagining what life on other planets, and intelligent life in particular, may be like is a long-running theme in human culture. It is a manifestation of the innate human curiosity…

JWST Lensed Quasar Dark Matter Survey III: Dark Matter Sensitive Flux Ratios and Warm Dark Matter Constraint from the Full Sample

R. E. Keeley, A. M. Nierenberg, D. Gilman +24

We present the full sample of measurements of the warm dust emission of 31 strongly-lensed, multiply imaged quasars, observed with JWST MIRI multiband imaging, which we use to cons…
