Aims. We provide an in-depth analysis of the COSMOS-Web ring, an Einstein ring at z ≈ 2 that we serendipitously discovered during the data reduction of the COSMOS-Web survey and that could be the most distant lens discovered to date. Methods. We e... Read More about The COSMOS-Web ring: In-depth characterization of an Einstein ring lensing system at z ∼ 2.
