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.

International Journal of Urban and Regional Research, EarlyView.Abstract Why do some informal neighborhoods receive public investment while others are neglected or evicted? This article addresses the inconsistent governmental responses to informal settlements in Jakarta, Indonesia, during the democratic period. State actions range from violent evictions to tolerance and community‐led improvements.

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 British Journal of Sociology, EarlyView.ABSTRACT In corporate graduate recruitment worldwide, candidates are often assessed not only on competence but on whether they are deemed relatable. This study theorises relatability as a racialised cultural–affective filter that covertly sustains inequality. Drawing on qualitative interviews, we identify five interlinked processes of self‐presentation,

Galaxy-Galaxy weak gravitational lensing in cluster environment
, 2012 An investigation was carried out into the phenomenon of galaxy-galaxy weak lensing in a sample of 10 X-ray selected galaxy clusters. Using high resolution Hubble Space Telescope imaging data and mathematical techniques described within, the feasibility ...

When Great Powers Struggle: How Geopolitical Alignments of Small States Are Influenced by Their MNEs
Journal of Management Studies, EarlyView.Abstract Comparing two distinct deglobalization periods, this study shows how Finnish multinational enterprises (MNEs) used corporate diplomatic activities (CDA) to influence Finland's alignment with a struggling great power. Drawing from hegemonic stability theory and new institutional economics, we argue that the power's collapsing global networks ...

Weak gravitational lensing with CO galaxies [PDF]
, 2018 Optical weak lensing surveys have become a powerful tool for precision cosmology, but remain subject to systematic effects that can severely bias cosmological parameter estimates if not carefully removed. We discuss the possibility of performing complementary weak lensing surveys at radio/microwave frequencies, using detections of CO-emitting galaxies ...

The Open Journal of AstrophysicsWe investigate stellar mass and central dark matter density profiles of photometric luminous red galaxies with stellar masses of $\sim10^{10}-10^{12}M_\odot$ using weak gravitational lensing measurements from the Hyper Suprime-Cam Subaru Strategic ...
