lenstronomy is an Astropy-affiliated Python package for gravitational lensing simulations and analyses. lenstronomy was introduced by Birrer and Amara (2018) and is based on the linear basis set approach by Birrer et a. (2015). The user and developer base of lenstronomy has substantially grown since then, and the software has become an integral part of a wide range of recent analyses, such as measuring the Hubble constant with time-delay strong lensing or constraining the nature of dark matter from resolved and unresolved small scale lensing distortion statistics. The modular design has allowed the community to incorporate innovative new methods, as well as to develop enhanced software and wrappers with more specific aims on top of the lenstronomy API. Through community engagement and involvement, lenstronomy has become a foundation of an ecosystem of affiliated packages extending the original scope of the software and proving its robustness and applicability at the forefront of the strong gravitational lensing community in an open source and reproducible manner.

  1. Strong Lensing Tomography: Double and pseudo multi-source plane strong gravitational lensing to constrain dark energy

    astro-ph.CO 2026-07 conditional novelty 7.0

    Pseudo double-source plane lenses enable statistical strong lensing tomography that forecasts σ(w0) ~ 0.45 from the LSST 10-year photometric sample in flat w0waCDM cosmology.

  2. ATLAS. II. Extremely High Incidence of Balmer Line Absorption with Predominant Blueshifts in LRDs: Statistical Insights through Comparison with Type 1 AGNs

    astro-ph.GA 2026-07 conditional novelty 6.0

    Balmer-line absorption occurs in ~35% (14/40) of JWST little-red-dot AGNs, roughly 850x the rate in SDSS type-1 AGNs, with mostly slow blueshifted absorber velocities.

  3. Probing Dark Matter Substructure with Wave-Optics Distortions of Strongly Lensed LISA Gravitational Waves

    astro-ph.CO 2026-07 conditional novelty 6.0

    Simulated four-year-LISA lensed waveforms show fuzzy-dark-matter substructure leaves a frequency-dependent phase residual that distinguishes it from NFW or self-interacting halos with ~60–110 resolved images.

  4. The free-streaming length of dark matter from JWST observations of 28 strong gravitational lenses

    astro-ph.CO 2026-06 unverdicted novelty 6.0

    JWST lensing data on 28 systems constrain dark matter free-streaming length to below 6-7 kpc and thermal relic mass above 6.5-7.4 keV, consistent with cold dark matter predictions.

  5. Investigating the Dark Energy Constraint from Strongly Lensed AGN at LSST-Scale

    astro-ph.CO 2025-11 conditional novelty 6.0

    A simulated sample of 800 LSST lensed AGN, analyzed with a new hierarchical time-delay inference code, is forecast to yield ~2.5% H0 precision and a dark-energy figure of merit of 6.7 in w0waCDM.

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

    astro-ph.CO 2025-11 conditional novelty 6.0

    Adding extended lensed arcs to quasar flux ratios in 28 JWST lenses tightens the dark-matter free-streaming limit to m_hm < 10^7.4 M⊙ (galacticus prior) and gives the most precise lensing measurement of subhalo abundance.

  7. Probing Dark Matter Substructure with Image Number Anomaly in Strong Lensing Systems

    astro-ph.CO 2025-11 unverdicted novelty 5.0

    Null detection of extra lensed images in 3500 mock systems constrains PBH abundance to ≲0.04-0.125% and excludes FDM masses below 0.4-3.5×10^{-22} eV at 95% CL depending on angular resolution.
