JWST/NIRSpec Observations of Lyman α Emission in Star-forming Galaxies at 6.5 ≲ z ≲ 13

The Astrophysical Journal
We present an analysis of JWST Ly α spectroscopy of z ≳ 6.5 galaxies, using observations in the public archive covering galaxies in four independent fields: Great Observatories Origins Deep Survey (GOODS)-N, GOODS-S, A2744, and the Extended Groth Strip ...

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

What Are the Pillars of Reionization? Revising the AGN Luminosity Function at z ∼ 5

The Astrophysical Journal
In the past, high- z active galactic nuclei (AGNs) were given a minor role as possible drivers of reionization, despite initial evidence in favor of their large space densities at low luminosities by Chandra and the Hubble Space Telescope.

Anthropology and change over the ‘land rights era’: Towards treaties?

The Australian Journal of Anthropology, EarlyView.
Abstract Australia has made no treaties with its Indigenous peoples. Despite that, over the past five decades (the ‘land rights era’ of the title), Australia has granted proportionally more land area to Indigenous interests than have other, treaty‐making Anglo settler colonies (Canada, the United States, New Zealand). Despite complexities of comparison

Newest Measurements of Hubble Constant from DESI 2024 Baryon Acoustic Oscillation Observations

The Astrophysical Journal Letters
In this Letter, we use the latest results from the Dark Energy Spectroscopic Instrument (DESI) survey to measure the Hubble constant. Baryon acoustic oscillation (BAO) observations released by the DESI survey, allow us to determine H _0 from the first ...
