A deconstruction of methods to derive one-point lensing statistics
The Open Journal of AstrophysicsGravitational lensing is a crucial tool for exploring cosmic phenomena, providing insights into galaxy clustering, dark matter, and dark energy. Given the substantial computational demands of $N$-body simulations, approximate methods like $\texttt ...

Gravitational lensing around Kehagias–Sfetsos compact objects surrounded by plasma
European Physical Journal C: Particles and Fields, 2019 We study the optical properties of the Kehagias–Sfetsos (KS) compact objects, characterized by the “Hořava” parameter $$\omega _{_{KS}}$$ ωKS , in the presence of plasma, considering its homogeneous or power-law density distribution.

Strong deflection gravitational lensing
, 2012 In this work are reviewed several aspects of gravitational lensing produced by astrophysical bodies that strongly curve the spacetime in their vicinity. When an object with a photon sphere (e.g. a black hole) is interposed between a source and an observer, in addition to primary and secondary images due to small deflections of the light rays, there are

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.

The Ties That Rhyme: Duality in Symbolic and Structural Networks of Grime Music
The British Journal of Sociology, EarlyView.ABSTRACT Do birds of a feather really sing together? Musicians face two competing pressures in the pursuit of success: conforming to genre norms to meet audience expectations and distinguishing themselves to attract the attention of listeners. These opposing logics may shape how artists choose their collaborators.

Mitigating Disinformation with Civic Constitutionalism: The Case Study of Taiwan
Global Policy, EarlyView.ABSTRACT Amid growing concerns over information integrity, disinformation has evolved into a broader and more complex phenomenon now recognized as Foreign Information Manipulation and Interference (FIMI), posing significant threats to democratic governance.

Gravitational lensing in the strong field limit [PDF]
Physical Review D, 2002 We provide an analytic method to discriminate among different types of black holes on the ground of their strong field gravitational lensing properties. We expand the deflection angle of the photon in the neighbourhood of complete capture, defining a strong field limit, in opposition to the standard weak field limit.

Change in migrants’ political attitudes: Acculturation and cosmopolitanization
American Journal of Political Science, EarlyView.Abstract This paper investigates change in international migrants’ political attitudes. It theorizes a novel attitudinal typology distinguishing polity‐specific attitudes influenced by national contexts and transnational attitudes forged by migratory experience. It applies the typology to four dimensions of political competition in contemporary Europe:

Beyond Bia Hơi? Distinction and Aspiration in Hanoi's Craft Beer Scene
Asia Pacific Viewpoint, EarlyView.ABSTRACT In this article we examine the emergence of Hanoi's craft beer scene as a window into shifting class identities, aspirational consumption, and local–global negotiations in contemporary Vietnam. We bring together Bourdieu's theorisation of taste as symbolic capital with Appadurai's concept of aspiration to analyse how consumption practices ...
