Weak gravitational lensing of background galaxies provides a direct probe of the projected matter distribution in and around galaxy clusters. Here we present a self-contained pedagogical review of cluster--galaxy weak lensing, covering a range of topics relevant to its cosmological and astrophysical applications. We begin by reviewing the theoretical foundations of gravitational lensing from first principles, with special attention to the basics and advanced techniques of weak gravitational lensing. We summarize and discuss key findings from recent cluster--galaxy weak-lensing studies on both observational and theoretical grounds, with a focus on cluster mass profiles, the concentration--mass relation, the splashback radius, and implications from extensive mass calibration efforts for cluster cosmology.

  1. Weak deflection angle of charged signal in magnetic fields

    gr-qc 2025-01 conditional novelty 6.0 of 10

    Weak deflection of charged signals in magnetized black hole spacetimes can be split into gravitational and electromagnetic parts, with magnetic dipole effects entering one order higher than electrostatic effects.

  2. Nonminimally coupled Dark Matter in Clusters of Galaxies: a fully comprehensive analysis

    astro-ph.CO 2024-12 conditional novelty 6.0 of 10

    A disformal dark matter-gravity coupling length is constrained to be very small by CLASH cluster lensing, consistent with general relativity.
