Evaporation of charged bosonic condensate in cosmology
Cosmological evolution of equilibrium plasma with a condensate of U(1)-charged bosonic field is considered. It is shown that the evaporation of the condensate is very much different from naive expectations, discussed in the literature, as well as from ...

KiDS-450: cosmological parameter constraints from tomographic weak gravitational lensing [PDF]
We present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ~450deg$^2$ of imaging data from the Kilo Degree Survey (KiDS).

Aspects of superstring cosmology are reviewed with an emphasis on the cosmological implications of duality symmetries in the theory. The string effective actions are summarized and toroidal compactification to four dimensions reviewed. Global symmetries that arise in the compactification are discussed and the duality relationships between the string ...

Abstract There is rising recognition of resource‐use rights of Indigenous Peoples and Local Communities (IPLCs) within wildlife conservation. Historically, sociocultural institutions ensured wildlife sustainability in many IPLC areas. However, the future viability of such institutions is uncertain as IPLCs change in response to external pressures and ...

We show that with the help of a suitable coupling between dark energy and cold dark matter it is possible to reproduce any scaling solution $ _{X}\propto _{M}a^ $, where $ _{X}$ and $ _{M}$ are the densities of dark energy and dark matter, respectively. We demonstrate how the case $ = 1$ alleviates the coincidence problem. Future observations of

Indigenous resurgence in the Blue Economy: Relational values to guide kelp mariculture
Abstract Decisions about how to use ocean spaces are increasingly attuned to issues of social equity, environmental sustainability and climate resilience, yet often bypass local governance, knowledge, values and thus objectives. To inform future decisions about kelp harvest and mariculture activities on the west coast of Canada, we co‐designed research

Dark Matter Substructure and Dwarf Galactic Satellites
A decade ago cosmological simulations of increasingly higher resolution were used to demonstrate that virialized regions of Cold Dark Matter (CDM) halos are filled with a multitude of dense,

We explore the cosmological solutions of a recently proposed extension of General Relativity with a Lorentz-invariant mass term. We show that the same constraint that removes the Boulware-Deser ghost in this theory also prohibits the existence of homogeneous and isotropic cosmological solutions.

We highlight the flexibility of the IPSO experiment-design framework by contrasting its application to CMB, weak lensing and redshift surveys. We illustrate the latter with a 10 parameter MCMC D-optimisation of a dark energy redshift survey. When averaged over a standard dark energy model space the resulting optimal survey typically has only one or two

Expanding the life framework of values
Abstract Conceptualising and organising the range of value orientations and worldviews underpinning human–nature relationships is useful for understanding different, and sometimes conflicting, perspectives on how nature should be managed and working towards just and equitable policies.
