Particle dynamics, black hole shadow and weak gravitational lensing in the f (Q) theory of gravity
Communications in Theoretical Physics, 2023We study the particle dynamics around a black hole (BH) in f(Q) gravity. First, we investigate the influence of the parameters of f(Q) gravity on the horizon structure of the BH, photon orbits and the radius of the innermost stable circular orbit (ISCO ...

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
2019Large-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 ...

A Weak Gravitational Lensing Cluster Survey
1999We are assembling deep, homogeneous optical observations of a statistically complete subset of clusters identified in the ROSAT Deep Cluster Survey. The mass of the clusters is determined via weak gravitational lensing, and correlated with the X-ray and optical properties.
