DETERMINE THE EFFECTIVE PARAMETERS IN GRAVITATIONAL LENSES AND STUDY THE ALTERNATIVE EFFECTS BETWEEN THEM [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2012 The importance of the gravitational lens in cosmology and astronomy, and a brief historical review for the evolution of the gravitational lenses have been introduced.

Gravitational Lensing of Continuous Gravitational Waves
Universe, 2021 Continuous gravitational waves are analogous to monochromatic light and could therefore be used to detect wave effects such as interference or diffraction. This would be possible with strongly lensed gravitational waves.

Can Einstein (rings) surf Gravitational Waves?
The Open Journal of Astrophysics, 2023 How does the appearance of a strongly lensed system change if a gravitational wave is produced by the lens? In this work we address this question by considering a supermassive black hole binary at the center of the lens emitting gravitational waves ...

Gravitational Lensing of Supernova Neutrino Bursts
Universe, 2021 Supernova neutrino bursts have been observed from extragalactic distances. This note addresses the question of how gravitational lensing could distort the information in the burst.

Fixed Points Features in N-Point Gravitational Lenses
East European Journal of Physics, 2019 A set of fixed points in N-point gravitational lenses is studied in the paper. We use complex form of lens mapping to study fixed points. There are some merits of using a complex form over coordinate. In coordinate form gravitational lens is described by

SOME COROLLARY FACTS OF THE N-POINT GRAVITATIONAL LENS EQUATION IN A COMPLEX FORM
Odessa Astronomical Publications, 2019 In the theory of the N-point gravita- tional lens equation, two groups of problems can be dis- tinguished. These are the so-called primal and inverse problems.

Odessa Astronomical Publications, 2017 In this paper, we study the correlation between the number of solutions of a system of lens equations and the number of source images that a gravitational lens has. We defined the concept of an image in a gravitational lens.

Motional Fock states for quantum-enhanced amplitude and phase measurements with trapped ions
Nature Communications, 2019 Quantum metrology allows surpassing the standard quantum limit, but methods relying on squeezing require to know the orientation of the squeezed quadrature with respect to the signal.

Fixed points of mapping of N-point gravitational lenses
Odessa Astronomical Publications, 2018 In this paper, we study fixed points of N-point gravitational lenses. We use complex form of lens mapping to study fixed points. Complex form has an advantage over coordinate one because we can describe N-point gravitational lens by system of two equation ...
