The paper presents a fully automated method for reconstructing the surface mass density of galaxy clusters using photometry and gravitational lensing data. It introduces DarkClusters-15k, a benchmark dataset of 15,000 simulated clusters with paired mass and photometry maps across multiple redshifts and simulation frameworks. By training a diffusion prior on this dataset, the authors generate posterior samples constrained by weak- and strong-lensing observables, achieving accurate, physics‑guided reconstructions with well‑calibrated uncertainties in minutes.

arXiv:2606. 00803v1 Announce Type: cross Abstract: Reconstructing the three-dimensional distribution of dark matter from weak-lensing observations is a central but highly ill-posed inverse problem in cosmology.
The study presents a deep‑learning approach (YOLOv11) trained on SDSS images to distinguish genuine dual active galactic nuclei (DAGN) from chance superpositions and foreground stars in the GOTHIC survey. Applying the model to 46,061 previously rejected candidates yields 29,605 dual‑nucleus candidates, with 54.5–62 % likely genuine, and a conservative subset of ~13,672 compact systems. The resulting catalogue refines the DAGN candidate list, reducing contamination and expanding the plausible census, though spectroscopic confirmation remains needed.
