Strong Gravitational Lensing by Kiselev Black Hole [PDF]
Physical Review D, 2015 We investigate the gravitational lensing scenario due to Schwarzschild-like black hole surrounded by quintessence (Kiselev black hole). We work for the special case of Kiselev black hole where we take the state parameter $w_{q}=-\frac{2}{3}$.

Strong Gravitational Lensing and Dark Energy Complementarity [PDF]
Physical Review D, 2004 In the search for the nature of dark energy most cosmological probes measure simple functions of the expansion rate. While powerful, these all involve roughly the same dependence on the dark energy equation of state parameters, with anticorrelation ...

Strong gravitational lenses from the Vera C. Rubin Observatory. [PDF]
Philos Trans A Math Phys Eng SciLike many areas of astrophysics and cosmology, the Vera C. Rubin Observatory will be transformational for almost all the applications of strong lensing, thanks to the dramatic increase in the number of known strong lenses by two orders of magnitude or more and the readily available time-domain data for the lenses with transient sources. In this article,

Strong Gravitational Lensing and Its Cosmic Constraints [PDF]
Modern Physics Letters A, 2013 In this paper, we propose a new method to use the strong lensing data sets to constrain a cosmological model. By taking the ratio $\mathcal{D}^{obs}_{ij}=\theta_{\mathrm{E_{\mathrm{i}}}}\sigma_{\mathrm{0_{\mathrm{j}}}}^2/\theta_{\mathrm{E_{\mathrm{j ...

A dearth of dark matter in strong gravitational lenses [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 I show that the lensing masses of the SLACS sample of strong gravitational lenses are consistent with the stellar masses determined from population synthesis models using the Salpeter IMF. This is true in the context of both General Relativity and modified Newtonian dynamics, and is in agreement with the expectation of MOND that there should be little ...

Image Simulations for Strong and Weak Gravitational Lensing [PDF]
Symmetry, 2020 Gravitational lensing has been identified as a powerful tool to address fundamental problems in astrophysics at different scales, ranging from exoplanet identification to dark energy and dark matter characterization in cosmology. Image simulations have played a fundamental role in the realization of the full potential of gravitational lensing by ...

Strong Gravitational Lensing with Gauss-Bonnet correction [PDF]
Journal of Cosmology and Astroparticle Physics, 2014 In this paper we investigate the strong gravitational lensing with Gauss-Bonnet gravity. By considering the logarithmic term for deflection angle, we obtain the deflection angle $\hat\alpha$ and corresponding parameters $\bar{a}$ and $\bar{b}$.
