Traces of Extra Dimensions in Cosmology [PDF]

, 2010
In this thesis, we discuss the observational consequences of extra dimensions on cosmological phenomena. We begin with an overview of extra dimensions, from the initial ideas of Kaluza and Klein to the more recent concept of braneworld models and in ...

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.

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]

, 2006
In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

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

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 ...

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.

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.

Cosmology with logarithmic corrected horizon entropy according to the generalized entropy and variable-G correspondence

Journal of High Energy Physics
According to the GEVAG (Generalized Entropy Varying-G) framework, any modification to the Bekenstein-Hawking area law would also lead to a varying-G gravity theory in which the effective gravitational constant G eff becomes area-dependent. Among a myriad

1172. Dendrobium chryseum Rolfe

Curtis's Botanical Magazine, EarlyView.
Summary Dendrobium chryseum is a widespread orchid from continental tropical Asia and Taiwan with a confused taxonomical history. In addition to its horticultural merits and its use in Traditional Chinese Medicine, this species has significant cultural importance among the Tsou people of Taiwan. Notes on pollination, cultivation, taxonomy, distribution,

Cosmology with One Galaxy: Autoencoding the Galaxy Properties Manifold

The Astrophysical Journal
Cosmological simulations like CAMELS and IllustrisTNG characterize hundreds of thousands of galaxies using various internal properties. Previous studies have demonstrated that machine learning can be used to infer the cosmological parameter Ω _m from the
