TL;DR: This detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB) is reported, a key first step for cluster cosmology with future low-noise CMB surveys, like CMB-S4, for which CMB polarization will be the primary channel for cluster lensing measurements.

TL;DR: In this paper, the authors present a catalogue of 2740 visually inspected galaxy clusters as a part of the SDSS Data Release 16 (DR16) and discuss the improvements of this catalogue's identification of cluster using 33,340 redshifts, with the median number of members per cluster is approximately 10, with 818 having 15 or greater.

TL;DR: In this article, the authors present an untriggered search for optical bursts with the Robotic Optical Transient Search Experiment (ROTSE-I) telephoto array, which reveals no candidate events.

TL;DR: In this article, the authors extend the measurement and modeling of the galaxy-galaxy lensing signal in the recent Dark Energy Survey Year 3 cosmology analysis to the highly nonlinear scales.

TL;DR: In this paper, the authors present a method of combining cluster abundances and large-scale two-point correlations, namely galaxy clustering, galaxy-cluster cross-correlations, cluster auto-relations, and cluster lensing.
