ВЛИЯНИЕ ГРАВИТАЦИОННОГО ЛИНЗИРОВАНИЯ НА ФУНКЦИЮ СВЕТИМОСТИ КВАЗАРОВ
Odessa Astronomical Publications, 2011 The function of quasar distribution on apparent brightness is discussed. This function is found on base of suggestion that quasars, at least partly, are strong gravitational lensing images of the active nuclei of distant galaxies.

Small, EarlyView.Aerosol Jet Printing (AJP), coupled with a novel in situ monitoring method, enabled the controlled fabrication of aligned and crumpled Ti3C2Tx MXenes for diverse applications. Demonstrated across multiple 2D materials, this scalable strategy stablishes flake morphology as a controllable design parameter for engineering application‐specific material ...

Weak Gravitational Lensing—The Need for Surveys [PDF]
Symposium - International Astronomical Union, 1997 Light rays from distant sources are deflected if they pass near an intervening matter inhomogeneity. This gravitational lens effect is responsible for the well-established lens systems like multiple-imaged QSOs, (radio) ‘Einstein’ rings, the giant luminous arcs in clusters of galaxies, and the flux variations of stars in the LMC and the Galactic bulge ...

Precision Measurement of Large Shear Signals
The Astrophysical Journal LettersSo far, estimators of galaxy shape distortions are only carefully studied perturbatively in the case of small shear signals, mainly for weak-lensing science.

TESOL Quarterly, EarlyView.Abstract English learners (ELs) in US K–12 schools face systemic barriers that constrain their college and career readiness. Although research has richly documented ELs' limited opportunities to learn in high school and barriers to postsecondary education, much less is known about how late‐arriving ELs move from high school to community college (CC ...

Weak Lensing and Gravity Theories
, 2005 We present the theory of weak gravitational lensing in cosmologies with generalized gravity, described in the Lagrangian by a generic function depending on the Ricci scalar and a non-minimally coupled scalar ...

Detecting gravitational lensing by matter currents
Astronomy & AstrophysicsWe explored the observational prospects for detecting gravitational lensing induced by cosmological matter currents, a relativistic correction to the standard density lensing effect arising from the motion of matter.

The Political Quarterly, EarlyView.Abstract This article offers a practitioner‐scholar reflection on the 2026 Tower Hamlets local elections, in which the Aspire party secured thirty‐three of forty‐five council seats, the Labour Party was reduced to five and the Green Party emerged as an equal opposition force.

The Bianchi identity and weak gravitational lensing
, 2005 We consider the Bianchi identity as a field equation for the distortion of the shapes of images produced by weak gravitational lensing. Using the spin coefficient formalism of Newman and Penrose (1962 J. Math. Phys.
