The 2dF Gravitational Lens Survey [PDF]
Publications of the Astronomical Society of Australia, 2001 AbstractThe 2 degree Field (2dF) galaxy redshift survey will involve obtaining spectra of approximately 2.5 105 objects which have previously been identified as galaxy candidates on morphological grounds. Included in these spectra should be about ten gravitationally-lensed quasars, all with low-redshift galaxies as deflectors (as the more common lenses

The strong gravitational lens finding challenge [PDF]
Astronomy & Astrophysics, 2019 Large-scale imaging surveys will increase the number of galaxy-scale strong lensing candidates by maybe three orders of magnitudes beyond the number known today. Finding these rare objects will require picking them out of at least tens of millions of images, and deriving scientific results from them will require quantifying the efficiency and bias of ...

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

British Educational Research Journal, Volume 48, Issue 6, Page 1145-1160, December 2022., 2022 Abstract Racism, as a covert but pervasive presence in teacher education in England, remains a major structural issue and its effects on student teachers who are Black and Asian are real and troubling. Their personal stories reveal multiple challenges and present empirical evidence that can usefully be analysed to examine their experience of daily ...

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.

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 ...

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.
