Bubbling saddles of the gravitational index

SciPost Physics
We consider the five-dimensional supergravity path integral that computes a supersymmetric index, and uncover a wealth of semiclassical saddles with bubbling topology.

Gravitational lens theory

Eos, Transactions American Geophysical Union, 1980
‘… imagine an observer, an isolated galaxy acting as a lens, and a quasar, nearly in a line. Two images would be formed on either side of the lens, and a third one would be formed near the center of the galaxy because the bending for central rays will be small.’ [Jerome Christian, in Physics Today, September 1980.

Cosmography with the Double-source-plane Strong Gravitational Lens AGEL150745+052256

The Astrophysical Journal
Strong gravitational lenses with two background sources at widely separated redshifts are a promising independent probe of cosmological parameters. We can use these systems, known as double-source-plane lenses (DSPLs), to measure the ratio ( β ) of ...

THE URBANOLOGISTS COME TO TOWN: Professional Life and Work in the Urban Solutions Industry

International Journal of Urban and Regional Research, EarlyView.
Abstract This article charts the upsurge of an eclectic global community of professionals new to the field of urban policy and governance, animated by playful and celebratory attitudes towards cities and urbanization: the urbanologists. It contributes to debates in critical urban theory and critical ethnographies of technology to problematize ...

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.

Relatability as a Racialised Construct in Corporate Graduate Recruitment: Revealing a Hidden Mechanism of Labour Market Exclusion for Black African Youth in South Africa

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,

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:

The Role of B Corp Certification in Uncertain Times: An Empirical Investigation

Business Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT This paper aims to examine whether B Corp certification enhances firms' ability to navigate uncertain times and how contingent factors affect its effectiveness. Building on Stakeholder Theory and the Resource‐Based View, we formulated a set of research hypotheses and tested them with a long‐term event study and an ordinary least squares ...

Probing massive gravitons in f(R) with lensed gravitational waves

Physics Letters B
We investigate the novel features of gravitational wave solutions in f(R) gravity under proper gauge considerations in the shifted Ricci scalar background curvature (R1+ϵ).

Ecologization Is Not a Metaphor: Museums in the Web of Life

Curator: The Museum Journal, EarlyView.
ABSTRACT This article documents and critiques emerging accounts of museum “ecologization”. Drawing on political ecology, materialist theory, and contemporary museum practice, we challenge dominant frameworks of ecological modernization and advocate for a more critical understanding of museums in the web of life.
