The Average Stellar Population Age and Metallicity of Intermediate-redshift Quiescent Galaxies

open access: yesThe Astrophysical Journal
The HectoMAP spectroscopic survey provides a unique mass-limited sample of more than 35,000 quiescent galaxies ( D _n 4000 > 1.5) covering the redshift range 0.2  10 ^11 M _⊙ ) assemble the bulk of their stars at earlier epochs.

Arbuscular mycorrhizal fungal community abundance, functions, and symbiotic interactions revealed by root metatranscriptomes

open access: yesiMetaOmics, EarlyView.
Paradigm shift: PCR‐free methods reveal 6–15‐fold higher arbuscular mycorrhizal (AM) fungal abundance than metabarcoding, exposing systematic underestimation across decades of research. Predictive power: AM fungal abundance serves as a community‐level trait that predicts crop yield under drought conditions.

Preparing the Besançon Galaxy model for the comparison with Gaia data

open access: yesEPJ Web of Conferences, 2012
From the Gaia mission, kinematic and star count data, together with the physical parameters of the stars - ages and metallicities-, will allow to characterise our Galaxy populations and, from that, the overall Galactic gravitational potential. One of the

The Arecibo Galaxy Environments survey IV: the NGC7448 region and the HI mass function [PDF]

open access: yes, 2010
In this paper we describe results from the Arecibo Galaxy Environments Survey (AGES). The survey reaches column densities of ~3x10^18 cm^-2 and masses of ~10^7 M_O, over individual regions of order 10 sq deg in size, out to a maximum velocity of 18,000 ...

Progress of metabolomics‐centric multi‐omics research in medicine

open access: yesiMetaOmics, EarlyView.
The graphical abstract illustrates a holistic roadmap for metabolomics‐centric multi‐omics integration in medical research. The upper panel depicts the technological transition from traditional bulk analysis to high‐resolution single‐cell and spatial methodologies, specifically addressing inherent challenges such as molecular complexity and dynamic ...

Ancient Relic Moderately Metal-rich Bulge Cluster Tonantzintla 2

open access: yesThe Astrophysical Journal Letters
The assembly history of the Galactic bulge is intimately tied to the formation of the proto–Milky Way, yet reconstructing this early phase is difficult because mergers and secular evolution have erased most of its original structure.

Dark ages reionization & galaxy formation simulation XII: Bubbles at dawn

open access: yes, 2017
Direct detection of regions of ionized hydrogen (HII) has been suggested as a promising probe of cosmic reionization. Observing the redshifted 21-cm signal of hydrogen from the epoch of reionization (EoR) is a key scientific driver behind new-generation,

Attitudes and behaviours of consumers towards plant‐based yoghurt alternatives: a cross‐cultural study

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Increased awareness of sustainable food production and vegan, vegetarian and flexitarian diets are driving the growth in dairy substitutes, particularly plant‐based yoghurts. To understand consumer perception or mind‐set and facilitate adoption of plant‐based yoghurt products, a multi‐phase study using both qualitative and ...
