Shadow and weak gravitational lensing for Ellis-Bronnikov wormhole

Chinese Physics C, High Energy Physics & Nuclear Physics, 2023
In this study, we investigated the gravitational weak lensing and shadow of the Ellis-Bronnikov wormhole. First, we studied the photon motion in a plasma medium and a wormhole shadow.

Plasma effects on weak gravitational lensing and shadows of Sen black holes

Chinese Physics C, High Energy Physics & Nuclear Physics
We investigate the optical properties of the spacetime surrounding a Sen black hole, focusing on the black hole shadow, weak gravitational lensing, and time delay effects. Our analysis reveals that the effective charge of the Sen black hole significantly

Weak Gravitational Lensing

2015
In this chapter, we summarize the basics of gravitational lensing. We derive the basic equation in gravitational lensing and summarize the relation between observables and physical quantities. We then introduce some statistical methodologies to extract cosmological information from gravitational lensing analysis.

Astrophysical Systematics in Weak Gravitational Lensing

2019
Large-scale structure surveys allow us to constrain cosmology through the growth of structure and the expansion history. Together with Cosmic Microwave Background (CMB) measurements from the early Universe, the standard CDM with general relativity has become a concordance model that explains the origin and evolution of our Universe for over thirteen ...
