abstract

We present the lens mass model of the quadruply-imaged gravitationally lensed quasar WFI2033-4723, and perform a blind cosmographical analysis based on this system. Our analysis combines (1) time-delay measurements from 14 years of data obtained by the COSmological MOnitoring of GRAvItational Lenses (COSMOGRAIL) collaboration, (2) high-resolution $\textit{Hubble Space Telescope}$ imaging, (3) a measurement of the velocity dispersion of the lens galaxy based on ESO-MUSE data, and (4) multi-band, wide-field imaging and spectroscopy characterizing the lens environment. We account for all known sources of systematics, including the influence of nearby perturbers and complex line-of-sight structure, as well as the parametrization of the light and mass profiles of the lensing galaxy. After unblinding, we determine the effective time-delay distance to be $4784_{-248}^{+399}~\mathrm{Mpc}$, an average precision of $6.6\%$. This translates to a Hubble constant $H_{0} = 71.6_{-4.9}^{+3.8}~\mathrm{km~s^{-1}~Mpc^{-1}}$, assuming a flat $\Lambda$CDM cosmology with a uniform prior on $\Omega_\mathrm{m}$ in the range [0.05, 0.5]. This work is part of the $H_0$ Lenses in COSMOGRAIL's Wellspring (H0LiCOW) collaboration, and the full time-delay cosmography results from a total of six strongly lensed systems are presented in a companion paper (H0LiCOW XIII).

  1. Warm dark matter chills out: constraints on the halo mass function and the free-streaming length of dark matter with 8 quadruple-image strong gravitational lenses

    astro-ph.CO 2019-08 conditional novelty 7.0 of 10

    Eight quadruple-image lenses bound the dark matter half-mode mass to below 10^7.8 solar masses, corresponding to a thermal relic mass above 5.2 keV, with substructure abundance consistent with cold dark matter.

  2. A model-independent determination of the Hubble constant from lensed quasars and supernovae using Gaussian process regression

    astro-ph.CO 2019-08 conditional novelty 6.0 of 10

    A Gaussian process reconstruction of supernova distances, anchored by four H0LiCOW lens time delays, gives H0 = 72.2 ± 2.1 km/s/Mpc in a flat universe without assuming a dark energy model.

  3. Disentangling the dark and stellar mass through precise lens modelling of the JWST observation of lensed quasar WFI2033--4723

    astro-ph.GA 2026-07 conditional novelty 5.0 of 10

    Composite time-delay lens modelling of JWST WFI2033–4723 yields intermediate stellar IMF normalisation and a steep gNFW inner slope γ_in≃1.3 that is robust to the choice of external cosmology.

  4. Model-independent late-universe measurements of $H_0$ and $\Omega_K$ with the parametrization based on cosmic age-improved inverse distance ladder

    astro-ph.CO 2025-10 conditional novelty 5.0 of 10

    A cosmic-age-based inverse distance ladder with DESI DR2, DESY5, SGL, CC and GRB data gives H0=71.59±0.94 km/s/Mpc and ΩK=0.001±0.038.

  5. Dissipative Unimodular Gravity: Linking Energy Diffusion to Bulk Viscosity as an Alternative to $\Lambda$CDM under DESI DR2 Data

    gr-qc 2026-01 conditional novelty 4.0 of 10

    A viscous version of unimodular gravity fits late-time cosmological data as well as ΛCDM, but the fitted viscosity is consistent with zero and the claimed energy nonconservation is not statistically significant.
