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…

TDCOSMO. XXVII. JWST-based Lens Models and H Measurement of WFI2033, HE0435, and PG1115

D. M. Williams, T. Treu, D. P. Johnson +13

Time-delay cosmography offers a one-step, distance-ladder-independent route to the Hubble-Lemaitre constant, H_0. We present new cosmography-grade lens models of three quadruply im…

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…

JWST lensed quasar dark matter survey IV: Stringent warm dark matter constraints from the joint reconstruction of extended lensed arcs and quasar flux ratios

D. Gilman, A. M. Nierenberg, T. Treu +23

We present a measurement of the free-streaming length of dark matter (DM) and subhalo abundance around 28 quadruple image strong lenses using observations from JWST MIRI presented…

TDCOSMO: XX. WFI2033--4723, the First Quadruply-Imaged Quasar Modeled with JWST Imaging

D. M. Williams, T. Treu, S. Birrer +5

Gravitational time delays offer unique, independent measurements of the Hubble constant, . Precise measurements of stand as one of the most pressing challenges in modern…

J1721+8842: The first Einstein zig-zag lens

F. Dux, M. Millon, C. Lemon +16

We report the discovery of the first example of an Einstein zig-zag lens, an extremely rare lensing configuration. In this system, J1721+8842, six images of the same background qua…

MMT/Binospec Spectroscopic Survey of Two 0.8 Galaxy Clusters in the Eye of Horus Field

Jiyun Di, Eiichi Egami, Kenneth C. Wong +4

The discovery of the Eye of Horus (EoH), a rare double source-plane lens system ( 0.795; 1.302 and 1.988), has also led to the identification of two h…
