Strong field limit analysis of gravitational retro-lensing
, 2003 We present a complete treatment in the strong field limit of gravitational retro-lensing by a static spherically symmetric compact object having a photon sphere.

INHERITANCE AND INCEST: TOWARD A LÉVI‐STRAUSSIAN READING OF MONTESQUIEU'S DE L'ESPRIT DES LOIS1
History and Theory, Volume 64, Issue 1, Page 46-74, March 2025.ABSTRACT The premise of this article is that Montesquieu, while seen as an Enlightenment thinker who contributed centrally to the development of the social sciences before the period of discipline formation in the nineteenth century, is generally appreciated in only the vaguest of terms.

Recent Developments in Degenerate Higher Order Scalar Tensor Theories
Annalen der Physik, Volume 537, Issue 2, February 2025.Degenerate Higher Order Scalar Tensor theories are reviewed, together with their applications in cosmology and astrophysics. These theories have been applied to build models of the early universe, in the description of the late‐time cosmic acceleration, as well as in astrophysics, including black hole physics. They have the potential to provide answers

An accurate and practical method for inference of weak gravitational lensing from galaxy images [PDF]
, 2015 We demonstrate highly accurate recovery of weak gravitational lensing shear using an implementation of the Bayesian Fourier Domain (BFD) method proposed by Bernstein & Armstrong (2014, BA14), extended to correct for selection biases. The BFD formalism is

Lensing by Kerr Black Holes. I: General Lens Equation and Magnification Formula
, 2011 We develop a unified, analytic framework for gravitational lensing by Kerr black holes. In this first paper we present a new, general lens equation and magnification formula governing lensing by a compact object. Our lens equation assumes that the source

Gravitational Effects on the Neutrino Oscillation [PDF]
, 1996 The propagation of neutrinos in a gravitational field is studied. A method of calculating a covariant quantum-mechanical phase in a curved space-time is presented.

Metaphilosophy, Volume 56, Issue 1, Page 35-51, January 2025.Abstract Some philosophical pluralists argue that a top‐down and a bottom‐up approach serve as equally justified methods for engaging in ontological inquiry. In the top‐down approach, we start with an analysis of theory and extrapolate from there to the world.

Measuring Omega_0 with higher-order Quasar-Galaxy Correlations induced by Weak Lensing [PDF]
, 2002 Via the magnification bias, gravitational lensing by large-scale structures causes angular cross-correlations between distant quasars and foreground galaxies on angular scales of arc minutes and above.

Seeking Languagelessness: Maker Literacies Mindsets to Disrupt Normative Practices
Reading Research Quarterly, Volume 59, Issue 3, Page 298-312, July/August/September 2024.This article challenges an over‐reliance on language as the primary means to communicate knowledge by adopting a languagelessness approach to maker pedagogies and maker literacies. Having conducted makerspace and design‐based research for some time, we separately and together noticed a productive relationship between wordless relational makerspace and ...

Primordial black holes from axion domain wall collapse
Journal of High Energy PhysicsThe QCD axion can solve the Strong CP Problem and be the dark matter of our universe. If the PQ symmetry breaking scale associated with the axion is below the inflationary reheating temperature, axion strings and domain walls populate the universe.
