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…

Emission-line galaxies at from near-IR HST Slitless Spectroscopy: metallicities, star formation rates and redshift confirmations from VLT/FORS2 spectroscopy

K. Boyett, A. J. Bunker, J Chevallard +14

We follow up emission line galaxies identified through the near-infrared slitless HST/WFC3 WISP survey with VLT/FORS2 optical spectroscopy. Over 4 WISP fields, we targetted 85 of 1…

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…

The role of density breaks in driving spiral structure in disc galaxies

Karl Fiteni, Sven De Rijcke, Victor P. Debattista +1

It is well established that stellar discs are destabilized by sharp features in their phase space, driving recurrent spiral modes. We explore the extent to which surface-density br…
