The Gaia-ESO Survey : Stellar content and elemental abundances in the massive cluster NGC 6705
(2014-09)Context. Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple populations. Aims. Studying the chemical ... -
The Gaia-ESO Survey : The analysis of high-resolution UVES spectra of FGK-type stars
(2014-11)Context. The ongoing Gaia-ESO Public Spectroscopic Survey is using FLAMES at the VLT to obtain high-quality medium-resolution Giraffe spectra for about 105 stars and high-resolution UVES spectra for about 5000 stars. With ... -
The Gaia-ESO Survey : the N/O abundance ratio in the Milky Way
(2018-10-01)Context. The abundance ratio N/O is a useful tool to study the interplay of galactic processes, for example star formation e ciency, timescale of infall, and outflow loading factor. Aims. We aim to trace log(N/O) versus ... -
The Gaia-ESO Survey: pre-main-sequence stars in the young open cluster NGC 3293
(2016-08-11)The young open cluster NGC3293 is included in the observing program of the Gaia-ESO survey (GES). The radial velocity values provided have been used to assign cluster membership probabilities by means of a single-variable ... -
The Gaia-ESO survey: the non-universality of the age-chemical-clocks-metallicity relations in the Galactic disc
(2020-07-21)In the era of large spectroscopic surveys, massive databases of high-quality spectra provide tools to outline a new picture of our Galaxy. In this framework, an important piece of information is provided by our ability to ... -
The Gaia/IPHAS and Gaia/KIS value-added catalogues
(2018-12-11)We present a sub-arcsecond crossmatch of Gaia DR2 against the INT Photometric Ha Survey of the Northern Galactic Plane Data Release 2 (IPHAS DR2) and the Kepler-INT Survey (KIS). The resulting value-added catalogues (VACs) ... -
Gaia21bty: An EXor light curve exhibiting a FUor spectrum
(2023-10-30)Gaia21bty, a pre-main sequence star that previously had shown aperiodic dips in its light curve, underwent a considerable Delta G~2.9 mag brightening that occurred over a few months between 2020 October - 2021 February. ... -
Gaia23bab: a new EXor
(2024-05-16)On March 6 2023, the Gaia telescope has alerted a 2-magnitude burst from Gaia23bab, a Young Stellar Object in the Galactic plane. We observed Gaia23bab with the Large Binocular Telescope obtaining optical and near-infrared ... -
Gain saturation in Nd:doped laser materials
(1982-07)Saturation of gain in Nd:doped silicate, phosphate, and fluorophosphate glasses, and in doped crystals of YAG and YLF was observed during amplification of 1064 and 1053 nm pulses with durations of 1. 0, 9. 0, and 50 ns. ... -
The gain-of-function G389R variant of the β1-adrenoceptor does not influence blood pressure or heart rate response to β-blockade in hypertensive subjects
(2000)Mutation scanning of the b1-adrenoceptor gene has identified a polymorphism, G389R, that markedly affects G-protein coupling of the receptor and resulting cAMP production. We have investigated the effect of this functionally ... -
Gaining access to agency and structure in industrial marketing theory : a critical pluralist approach
(2014-12-01)This paper is concerned with gaining greater insight into the interplay between agency and structure in industrial marketing scholarship. The paper’s intent is to embed Midgley’s notion of critical pluralism within this ... -
Gaining an Empathetic Insight into Parenting: Evaluating Infant Simulator Dolls for Professional Learning
(2024-02-01)The development of an empathetic approach when working with parents and families is fundamental to both social work and children’s nursing; however, opportunities to develop this are limited. RealCare infant simulation ... -
Gaining insight into food, diet practices and nutrition during the early year’s lifespan: Preconception and pregnancy

Gaining professional recognition: exploring professionality and professional identity of early years practitioners in higher education
(2020-02-11)Professionalisation of the early years workforce internationally foregrounds what it means to gain professional recognition as an early years practitioner and has important implications for developing vocational programmes ... -
Gait Trajectory Prediction using Gaussian Process Ensembles
(Institute of Electrical and Electronics Engineers (IEEE), 2014)The development of robotic devices for the rehabilitation of gait is a growing area of interest in the engineering rehabilitation community. The problem with modelling gait dynamics is that everybody walks differently. The ... -
Galactic 26Al traces metal loss through hot chimneys
(2021-02-01)Radioactive 26Al is an excellent tracer for metal ejection in the Milky Way, and can provide a direct constraint on the modelling of supernova feedback in galaxy evolution. Gamma-ray observations of the 26Al decay line ... -
GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey I : A low-frequency extragalactic catalogue
(2017-01-01)Using the Murchison Widefield Array (MWA), the low-frequency Square Kilometre Array (SKA1 LOW) precursor located in Western Australia, we have completed the GaLactic and Extragalactic All-sky MWA (GLEAM) survey, and present ... -
Galactic chemical evolution : Carbon through zinc
(2006-12-20)We calculate the evolution of heavy-element abundances from C to Zn in the solar neighborhood, adopting our new nucleosynthesis yields. Our yields are calculated for wide ranges of metallicity (Z = 0-Z circle dot) and the ... -
The galactic population of white dwarfs
(2009)The contribution of white dwarfs of the different Galactic populations to the stellar content of our Galaxy is only poorly known. Some authors claim a vast population of halo white dwarfs, which would be in accordance with ...
