COSMOLOGICAL MARKINGS AND ERASURES: The Political Theology of State‐Led Gentrification and Heritagization

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract This article investigates the symbolic politics of state‐led gentrification and heritagization, focusing on how these processes serve to ‘glorify’ state power. Drawing on Agamben's political theology, Bourdieu's notion of symbolic power and space, and political heritage studies, we argue that the symbolic politics of state glorification can ...

New Tests of the Cosmic Distance Duality Relation with DESI 2024 Baryon Acoustic Oscillation Observations

open access: yesThe Astrophysical Journal
In this paper, we test the cosmic distance duality relation (CDDR), as required by the Etherington reciprocity theorem, which connects the angular diameter distance and the luminosity distance via the relation D _L ( z ) =  D _A ( z )(1 +  z ) ^2 .

Late Antique Allāh: Ancestral Arabian Religion and the Monotheistic Zeitgeist

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT This essay addresses the ongoing scholarly tension between the monotheistic interpretations of late pre‐Islamic Arabian religion, pioneered by G. Hawting and P. Crone, and the traditional accounts of rampant Arabian polytheism found in later Islamic literary sources.

Probing the Environment around GW170817 with DESI: Insights on Galaxy Group Peculiar Velocities for Standard Siren Measurements

open access: yesThe Astrophysical Journal
We present a new measurement of the Hubble constant, H _0 , following the gravitational-wave event GW170817 and Dark Energy Spectroscopic Instrument (DESI) observations.

Topology‐based Visual Analysis of Hydrothermal Plumes

open access: yesComputer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Smoking-gun Signatures of Bounce Cosmology from Echoes of Relic Gravitational Waves

open access: yesThe Astrophysical Journal Letters
We report a novel feature of relic gravitational waves (GWs) in nonsingular bounce cosmologies that is testable in light of GW astronomy. In nonsingular bounce cosmologies, the effective potential ${M}_{p}^{2}{a}^{{\prime\prime} }/a$ that governs the ...

Methodology of Observational Cosmology

open access: yes, 2002
These lectures focus on the methods of observational cosmology and their physical basis. After a brief reminder of the essential elements of the Big Bang model, we look at some of the basic methods for surveying the homogeneous universe.

Scalable Computation of Topological Abstractions for Scalar Data

open access: yesComputer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

The LBT Yp Project. III. LUCI Spectra of Metal-poor Nebulae

open access: yesThe Astrophysical Journal
Accurately determining the elemental abundances of a low-metallicity nebula strongly depends on measuring the density ( n _e ) and temperature ( T _e ) of the gas.
