Observational cosmology and the cosmic distance-duality relation
, 2014 We study the validity of cosmic distance duality relation between angular diameter and luminosity distances. To test this duality relation we use the latest Union2 Supernovae Type Ia (SNe Ia) data for estimating the luminosity distance. The estimation of

The generations of cultural ecosystem services research
Conservation Biology, EarlyView.Abstract Understanding the cultural dimensions of human–nature relationships and integrating them into decision‐making is a central goal of conservation social science. One prominent avenue for this work is the characterization and analysis of cultural ecosystem services (CES) (i.e., nonmaterial aspects of the benefits derived from human–nature ...

Primordial Non-Gaussianity in the Cosmic Microwave Background [PDF]
, 2010 In the last few decades, advances in observational cosmology have given us a standard model of cosmology. We know the content of the universe to within a few percent.

Conservation Biology, EarlyView.Abstract As biocultural approaches to conservation gain traction (e.g., through international commitments to Indigenous Peoples and local communities) and external conservation actors increasingly seek to engage with on‐the‐ground holders of biocultural diversity, improved understanding is needed of what biocultural diversity means.

The Astrophysical JournalWe test and compare coasting cosmological models with curvature parameters $k=\left\{-1,0,+1\right\}$ in ${H}_{0}^{2}{c}^{-2}$ units and the flat ΛCDM model by fitting them to cosmic chronometers (CCs), the Pantheon+ sample of Type Ia supernovae (SNe ...

Observational constraints on late-time Lambda(t) cosmology
, 2008 The cosmological constant, i.e., the energy density stored in the true vacuum state of all existing fields in the Universe, is the simplest and the most natural possibility to describe the current cosmic acceleration.

Is Planckian Discreteness Observable in Cosmology?
UniverseA Planck scale inflationary era—in a quantum gravity theory predicting discreteness of quantum geometry at the fundamental scale—produces the scale-invariant spectrum of inhomogeneities with a very small tensor-to-scalar ratio of perturbations and a hot big bang leading to a natural dark matter genesis scenario. Here, we evoke the possibility that some

A Spiritual Dimension of Human–Animal Relations?
Dialog, EarlyView.ABSTRACT A close relationship with nature and animals is widely acknowledged to support human physical, social, and mental health, but is more seldom considered relevant for human spirituality. Using theological resources, this paper argues that some human–animal relations may possess spiritual qualities.

Living Reviews in Relativity, 2001 This is a review of the physics and cosmology of the cosmological constant. Focusing on recent developments, I present a pedagogical overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the ...

Effects of Type Ia Supernovae Absolute Magnitude Priors on the Hubble Constant Value
The Astrophysical Journal LettersWe systematically explore the influence of the prior of the peak absolute magnitude ( M ) of Type Ia supernovae (SNe Ia) on the measurement of the Hubble constant ( H _0 ) from SNe Ia observations.
