Constraining on the non-standard cosmological models combining the observations of high-redshift quasars and BAO

open access: yesEuropean Physical Journal C: Particles and Fields
In this work, we studied four types of cosmological models with different mechanisms driving the accelerated expansion of the universe, include Braneworld models, Chaplygin Gas models, Emergent Dark Energy models, and cosmological torsion models ...

Caring with forests: Human and more‐than‐human care in forest occupations in Germany

open access: yesPeople and Nature, EarlyView.
Abstract Drawing on ongoing ethnographic and participatory action research within forest occupations in Germany, this paper develops the concept of ‘caring with forests’ to theorise the mutual, multidimensional relationships of care that emerge between humans and more‐than‐human beings in environmental protest settings.

On models of Cosmology

open access: yes, 2021
In this work the most promising string cosmology models are re-viewed model by model in detail. These models are based on conceptsform string theory and heterotic M theory to construct possible scenar-ios for the beginning and the evolution of the universe.

An interdisciplinary perspective on the interpretation of legal‐scientific concepts in rights‐of‐nature initiatives

open access: yesPeople and Nature, EarlyView.
Abstract Despite an ever‐growing body of environmental laws, biodiversity loss and climate breakdown persist globally. This has prompted debate over whether existing legal regimes can be strengthened sufficiently to address these crises, or whether more transformative legal approaches are needed The concept of rights of nature, which is gaining ...

Care through cultivation: Indigenous Swidden agriculture as forest care

open access: yesPeople and Nature, EarlyView.
Abstract This paper argues that the agricultural practices of Bunong swidden cultivators in northeastern Cambodia constitute relational care for forests that is fundamentally misunderstood, misrecognized, and marginalized by dominant state policies, conservation, and development paradigms. Bringing together care theory, long‐term ethnographic research,

Bulk viscous cosmological models with a cosmological constant: Observational constraints

open access: yesAstronomy & Astrophysics
Aims. We investigate whether viscous cold dark matter (vCDM) in a Λ-dominated Friedmann-Lemaître-Robertson-Walker (FLRW) universe can alleviate the Hubble tension, while satisfying thermodynamic constraints.

Cosmological models with both radiation and matter

open access: yes, 1985
A class of flat, homogeneous and isotropic, relativistic cosmological models containing both radiation and pressure-free matter is investigated.
