Gravitational lensing by hairy black holes in Einstein-scalar-Gauss-Bonnet theories

- Physics
- 2021

We investigate the weak and strong deflection gravitational lensing by the hairy black holes in the Einstein-scalar-Gauss-Bonnet (EsGB) gravity with five types of coupling functions (quadratic,… Expand

An examination of geometrical and potential time delays in gravitational lensing

- Physics
- 2020

In this paper we investigate the relation between the potential, and the geometrical time delays in the gravitational lensing. In the original paper of Shapiro (1964), it is stated that there is a… Expand

Can Weak Field Lensing Distinguish Between a Naked Singularity, an Ellis-Bronnikov Regular Wormhole and a Black Hole?

- Physics
- 2020

Abstract The purpose of this paper is to investigate if the weak field lensing (WFL) observables can distinguish between three physically distinct lenses, mathematically connected by a combination of… Expand

Gravitational Microlensing Event Statistics for the Zwicky Transient Facility

- Physics
- 2020

Microlensing surveys have discovered thousands of events with almost all events discovered within the Galactic bulge or toward the Magellanic clouds. The Zwicky Transient Facility (ZTF), while not… Expand

Gravitational lensing by charged black hole in regularized 4D Einstein–Gauss–Bonnet gravity

- Physics
- 2020

Among the higher curvature gravities, the most extensively studied theory is the so-called Einstein-Gauss-Bonnet (EGB) gravity, whose Lagrangian contains Einstein term with the GB combination of… Expand

Motion and collision of particles near Plebanski-Demianski black hole: Shadow and gravitational lensing

- Physics
- 2020

Abstract Here we consider accelerating and rotating charged Plebanski-Demianski (PD) class of black hole metric as a particle accelerator. We obtain the geodesic motions (timelike, null and… Expand

A large lunar telescope with a 50–100 m aperture based on ESO's Overwhelmingly Large Telescope concept will allow Intensity Interferometric measurements when coupled with large Earth-based telescopes, leading to picosecond angular resolution. Expand

Predictions of Gaia’s prize microlensing events are flawed

- Physics
- 2020

Precision astrometry from the second Gaia data release has allowed astronomers to predict 5,787 microlensing events, with 528 of these having maximums within the extended Gaia mission (J2014.5 -… Expand
