Testing quantum gravity with primordial gravitational waves

Journal of High Energy Physics
We propose a testable alternative to inflation directly built in a very general class of ultraviolet complete theories of quantum gravity enjoying Weyl invariance.

Observable (?) cosmological signatures of superstring models

, 2005
The different couplings of the dilaton to the U(1) gauge field of heterotic and Type I superstrings may leave an imprint on the relics of the very early cosmological evolution.

Un/Learning Adult Frames of Reference in Death Enquiries: Thinking~With a Picturebook, Philosophical Animism and Ontological Tact

Children &Society, EarlyView.
ABSTRACT Developmental psychology continues to shape how adults engage with children about death and dying. This influences whether children are included in rituals surrounding human and other‐than‐human bodies. Figurations of the innocent, immature and vulnerable child still dominate adult imaginaries of young children's understandings of mortality ...

Objects of Affection: Deathly Encounters With Taxidermy, Stuffed Toys and Atmospheres

Children &Society, EarlyView.
ABSTRACT This paper explores how children and young people relate to death through affective atmospheres and embodied, imaginative encounters with taxidermy and stuffed toy animals. Using arts‐based research (ABR), we explore how death, affective atmospheres, empathy and materiality entangle during multispecies relations.

Growth factor in teleparallel Gauss-Bonnet gravity

Physics Letters B
Teleparallel gravity offers a competing geometric framework on which to build cosmological models. The Gauss-Bonnet invariant captures key aspects of the underlying geometry that has been shown to be an interesting way to form cosmological models beyond ...

‘Mature’ and ‘Immature’ Death Concepts: Epistemic Injustice and Young Children's Sense‐Making of Death and Dying

Children &Society, EarlyView.
ABSTRACT Most research in Death Studies focuses on adult perspectives. Even when children are the intended focus, this research often remains adult‐centred due to the dominance of developmental psychology. A key concept underpinning this approach is the ‘mature death concept’ (MDC), a normative framework that assumes children's understanding of death ...

The obsolescence of protected area categories in a polycrisis world

Conservation Biology, EarlyView.
Abstract Current global conservation models face significant limitations in addressing the global polycrisis, and the constraints of the International Union for Conservation of Nature protected area (PA) classification system are part of the issue. The principles of the new conservation paradigm—governance, equity, and interculturality—are not viable ...

Testing the scalar weak gravity conjecture in no-scale supergravity

Journal of High Energy Physics
We explore possible extensions of the Weak Gravity Conjecture (WGC) to scalar field theories. To avoid charged black hole remnants, the WGC requires the existence of a particle with a mass m ≤ gqM P , with charge q and U(1) gauge coupling g, allowing the

Similar or Different? Configurations of Authenticity Across Museum Types

Curator: The Museum Journal, EarlyView.
ABSTRACT Authenticity is traditionally regarded as playing a crucial role in museums, science centers, and memorials. However, despite this fact, authenticity has very different meanings in different (institutional) settings. This complicates shared communications across museum practices.

On pre-inflationary non Gaussianities

Journal of High Energy Physics
We explore the three-point amplitude of curvature perturbations in scenarios suggested by high-scale supersymmetry breaking in String Theory, where the inflaton is forced to climb a steep exponential potential.
