Sound-horizon-agnostic Inference of the Hubble Constant and Neutrino Masses from Baryon Acoustic Oscillations, Cosmic Microwave Background Lensing, and Galaxy Weak Lensing and Clustering

The Astrophysical Journal Letters
We present a sound-horizon-agnostic determination of the Hubble constant, H _0 , by combining DESI Data Release 2 baryon acoustic oscillations (BAO) data with the latest cosmic microwave background (CMB) lensing measurements from Planck, the Atacama ...

Cosmological applications in Kaluza-Klein theory

, 2012
The field equations of Kaluza-Klein (KK) theory have been applied in the domain of cosmology. These equations are solved for a flat universe by taking the gravitational and the cosmological constants as a function of time t.

The Analogia Entis for Reformed Theology: Retrieving Calvin's Implicit Metaphysics

Modern Theology, EarlyView.
Abstract The famous controversy between Emil Brunner and Karl Barth which led to Barth's ‘No!’ was driven by disagreements over how to read John Calvin: Barth and Brunner never agreed on whether Calvin had a doctrine of the analogy of being. This article rekindles the debate.

Participatory Science and Machine Learning Applied to Millions of Sources in the Hobby–Eberly Telescope Dark Energy Experiment

The Astrophysical Journal
We are merging a large participatory science effort with machine learning to enhance the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX). Our overall goal is to remove false positives, allowing us to use lower signal-to-noise data and sources with

The Impacts of Weather Variability and Shocks on Farmers and Indigenous Peoples' Consumption: Evidence From Panama

Review of Development Economics, EarlyView.
ABSTRACT Weather variability and shocks pose significant challenges for tropical developing countries, making it crucial to understand their effects on consumption to address the existing deficiencies among the most vulnerable groups. This study examines the impact of weather variability and shocks on household consumption in Panama, utilizing repeated

Cosmological Parameters 2000

, 2000
The cosmological parameters that I emphasize are the age of the universe $t_0$, the Hubble parameter $H_0 \equiv 100 h$ km s$^{-1}$ Mpc$^{-1}$, the average matter density $ _m$, the baryonic matter density $ _b$, the neutrino density $ _ $, and the cosmological constant $ _ $. The evidence currently favors $t_0 \approx 13$ Gyr, $h \approx 0.65$, $

Refitting Cosmological Data with Neutrino Mass and Degeneracy

The Astrophysical Journal Letters
A simple and natural extension of the standard Lambda cold dark matter (ΛCDM) model is to allow relic neutrinos to have finite chemical potentials. We confront this ΛCDM ξ model, a ΛCDM with neutrino mass M _ν and degeneracy ξ _3 as additional parameters,

Parameter Estimation from Improved Measurements of the Cosmic Microwave Background from QUaD [PDF]

, 2010
We evaluate the contribution of cosmic microwave background (CMB) polarization spectra to cosmological parameter constraints. We produce cosmological parameters using high-quality CMB polarization data from the ground-based QUaD experiment and ...

Generalized Holographic Cosmology

, 2012
We consider general black hole solutions in five-dimensional spacetime in the presence of a negative cosmological constant. We obtain a cosmological evolution via the gravity/gauge theory duality (holography) by defining appropriate boundary conditions ...

The Right to Exist as the Foundation of Equal Citizenship: An Ontological Inquiry of State‐Citizen Relations in Türkiye

Studies in Ethnicity and Nationalism, EarlyView.
ABSTRACT Despite enduring decades of advocacy, Alevi communities in Türkiye find themselves in a constant state of anticipation for acknowledgment from the Turkish state. Previous studies have long documented the marginalized status of Alevis within Turkish society and their ongoing struggle for recognition; however, they have overwhelmingly framed the
