Probing the Universe with Weak Lensing [PDF]
Ann.Rev.Astron.Astrophys. 37 (1999) 127-189, 1998 Gravitational lenses can provide crucial information on the geometry of the Universe, on the cosmological scenario of formation of its structures as well as on the history of its components with look-back time. In this review, I focus on the most recent results obtained during the last five years from the analysis of the weak lensing regime.

Conflict Resolution Quarterly, EarlyView.ABSTRACT Building on Walter Isard's location and gravity theories in economics, we extend his trade model to better understand its core principles, including commercial attraction, center of gravity in markets, and favorable location for exporting firms.

European Physical Journal C: Particles and FieldsIn this manuscript, we provide a comprehensive study of gravitational lensing by dark compact objects predicted by modified gravity (MOG) based on the scalar–vector–tensor action, with the aim of providing new insights into the nature of gravitational ...

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 ...

The Depositional Record, EarlyView.The Upper Permian Castile Formation of the Delaware Basin, a 515.3 m (1690.6 ft) thick deep‐water evaporitic sequence dominated by anhydrite and halite, is the focus of this study. This study's sedimentological and geochemical analysis of cores from the basin's centre and margin reveals that dynamic reflux of deep hypersaline brines significantly ...

Lacustrine and fan‐delta sediments in syn‐rift lake basins
The Depositional Record, EarlyView.A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

Dynamics of Fermat potentials in non-perturbative gravitational lensing
, 2002 We present a framework, based on the null-surface formulation of general relativity, for discussing the dynamics of Fermat potentials for gravitational lensing in a generic situation without approximations of any kind.

Reputational risk and target selection: An evidence from China
International Journal of Finance &Economics, EarlyView.Abstract Do bidders with pre‐deal lower (higher) reputational risk select targets with lower (higher) reputational risk in the existing and new markets? Past research on the role of reputation suggests that reputable firms make conservative investment decisions to maintain their reputation.

Particle dynamics and gravitational weak lensing around black hole in the Kalb-Ramond gravity
European Physical Journal C: Particles and Fields, 2022 In this paper, we have studied the particle dynamics, gravitational lensing and energy processes around the black hole (BH) in Kalb–Ramond (KR) gravity.
