Abstract: We present a set of predictions for weak lensing correlation functions in the context of modified gravity models, including a prescription for the impact of the non-linear power spectrum ...

T he Perseus cluster is enormous. It has a mass equivalent to 600 trillion Suns, and it looks like it has not stopped growing. New evidence suggests that it is undergoing a merging process with ...

Abstract: Accurate photometric redshifts are among the key requirements for precision weak lensing measurements. Both the large size of the Sloan Digital Sky Survey (SDSS) and the existence of large ...

This book provides a comprehensive and self-contained exposition of gravitational lensing phenomena. It presents the up-to-date status of gravitational lensing and microlensing, covering the ...

Euclid's first data release offers a breathtaking glimpse into our universe, revealing over 26 million galaxies and ...

Hadzhiyska said. “We make a quantification of how much more extended that is, and that can then be plugged into this analysis of weak lensing in order to essentially disentangle effects related ...

NSF–DOE Vera C. Rubin Observatory is gearing up to illuminate the universe’s darkest secrets with groundbreaking new ...

Today, we are going to get a little more in the weeds as we discuss two different types of grips: strong ones and weak ones. Once you start getting a little more in the weeds as it pertains to ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as "antigravity," undoing the work of gravity, which clumps together matter to build vast ...
