First Light And Reionization Epoch Simulations (FLARES) XXI: The UV Indices of Galaxies in the Early Universe
Connor Sant Fournier, Stephen M. Wilkins, Joseph Caruana +5
UV absorption line indices trace chemical enrichment and star formation histories in high-redshift galaxies, yet their reliability as quantitative stellar metallicity, Z*, diagnost…
The edge of the Milky Way's star-forming disc: Evidence from a 'U-shaped' stellar age profile
Karl Fiteni, Stuart Robert Anderson, Victor. P. Debattista +7
We leveraged reliable age and distance estimates from LAMOST-DR3 and APOGEE-DR17+AstroNN combined with \gaia\ data to perform a detailed analysis of the stellar age distribution in…
EPOCHS VI: The Size and Shape Evolution of Galaxies since z ~ 8 with JWST Observations
K. Ormerod, C. J. Conselice, N. J. Adams +8
We present the results of a size and structural analysis of 1395 galaxies at with stellar masses 9.5 within the JWST…
First Light and Reionization Epoch Simulations (FLARES) -- XVIII: the ionising emissivities and hydrogen recombination line properties of early AGN
Stephen M. Wilkins, Aswin P. Vijayan, Scott Hagen +10
One of the most remarkable results from the \emph{James Webb Space Telescope} has been the discovery of a large population of compact sources exhibiting strong broad H emission…
Like a candle in the wind: The embers of once aflame, now smouldering galaxies at
James Trussler, Christopher Conselice, Nathan Adams +8
We develop a photometric search method for identifying smouldering galaxies at , which are defined to have weak emission lines and thus generally have low specific star f…
EPOCHS IV: SED Modelling Assumptions and their impact on the Stellar Mass Function at 6.5 < z < 13.5 using PEARLS and public JWST observations
Thomas Harvey, Christopher J. Conselice, Nathan J. Adams +31
We utilize deep JWST NIRCam observations for the first direct constraints on the Galaxy Stellar Mass Function (GSMF) at . Our EPOCHS v1 sample includes 1120 galaxy candidates…
