Image of Kerr–de Sitter black holes illuminated by equatorial thin accretion disks

European Physical Journal C: Particles and Fields
To explore the influence of the cosmological constant on black hole images, we have developed a comprehensive analytical method for simulating images of Kerr–de Sitter black holes illuminated by equatorial thin accretion disks. Through the application of

Anhydrous minerals in asteroid Bennu: Evidence for well‐preserved primordial components

Meteoritics &Planetary Science, EarlyView.
Abstract Aqueously altered carbonaceous astromaterials are dominated by secondary minerals, but a minor fraction of primary, anhydrous silicates and oxides escape alteration, offering insight into the original composition of asteroid parent bodies. We report the mineralogy, petrology, mineral chemistry, and oxygen isotopes of anhydrous minerals—50 ...

Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Extracting vitalities: Cuts in Indigenous women's bodies‐territories (Brazil)

Medical Anthropology Quarterly, EarlyView.
Abstract In this article, I explore the connections between the medicalization of childbirth and environmental devastation through Guarani‐Mbyá understandings of life and the living. I argue that the cuts made to Guarani‐Mbyá women's vaginas (episiotomies) in Brazilian hospitals are experienced and situated on the same cosmopolitical level as the cuts ...

THE FATHERS, COMPUTERS AND US

Modern Theology, EarlyView.
Abstract This essay, designed as a complement to opinions expressed by Rowan Williams and some speakers at the conference in his honour, explores features of early Christianity which suggest a positive evaluation of artificial intelligence. Noting that the fear of reducing humans to machines has been joined in the modern age by the fear that machines ...

Cosmic clues: DESI, dark energy, and the cosmological constant problem

Journal of High Energy Physics
Several attempts to solve the cosmological constant problem, which concerns the value of the cosmological constant being extremely smaller than the Standard Model mass scales, have introduced a scalar field with a very flat potential that can be ...

Cosmological Constant or Cosmological Potential

, 2000
In the framework of a model of minimal of dilatonic gravity (MDG) with cosmological potential we consider: the relations of MDG with nonlinear gravity and string theory; natural cosmological units, defined by cosmological constant; the properties of cosmological factor, derived from solar system and Earth-surface gravitational experiments; universal ...

Theologies of Mind: Eriugena and Pratyabhijñā Śaivism

Modern Theology, EarlyView.
Abstract Though Eriugena's affinities with several Hindu traditions are clear, this article offers to my knowledge the first detailed discussion of Eriugena's theology in relation to any Indic theological school, here, the nondualist Śaiva tradition known as the Pratyabhijñā (“Recognition”) lineage.

The Analogia Entis for Reformed Theology: Retrieving Calvin's Implicit Metaphysics

Modern Theology, EarlyView.
Abstract The famous controversy between Emil Brunner and Karl Barth which led to Barth's ‘No!’ was driven by disagreements over how to read John Calvin: Barth and Brunner never agreed on whether Calvin had a doctrine of the analogy of being. This article rekindles the debate.

Navigating troubled waters: Posthumanist vulnerability and entanglement in Richard Powers's Playground (2024)

Orbis Litterarum, EarlyView.
Abstract Richard Powers's most recent novels to date—The Overstory (2018), Bewilderment (2021), and Playground (2024)—engage with some of the environmental and technological threats that loom over our planet, such as deforestation, species loss, the degradation of the ocean bottom, and the risks associated with the development of generative AI ...
