Defect-Mediated Conversion: Dark Matter from Cosmological Domain-Wall Scattering
João Paulo Pinheiro, Mohamed Younes Sassi
We propose a new mechanism for dark matter genesis, \emph{Defect-Mediated Conversion} (DMC). Cosmological domain walls can host a scalar condensate in their core acting as a mixing…
First Light and Assembly of GalaxieS (FLAGS) I: The JWST/NIRCam Number Counts and IGL as Constraints on Galaxy Formation Models
Jack C. Turner, Stephen M. Wilkins, Aswin P. Vijayan
JWST observations have been used in conjunction with SED fitting to infer the physical properties of galaxies throughout cosmic time, revealing tensions with the predictions of the…
Stellar photoionisation modelling in SYNTHESIZER
Aswin P. Vijayan, Stephen M. Wilkins, Sophie L. Newman +5
The paper introduces photoionised gas emission modeling into the SYNTHESIZER code, allowing realistic stellar and nebular spectra to be generated for galaxy formation studies.
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…
An innovative alternative to traditional funding streams for extragalactic astronomy
Stephen M. Wilkins, Jack Turner, Connor Sant Fournier +2
With traditional sources of funding for astronomical research under increasing pressure, it is timely to explore innovative alternative mechanisms. We therefore introduce GalaxyCoi…
The Nature of High-Redshift Massive Quiescent Galaxies -- Searching for RUBIES-UDS-QG-z7 in FLARES
Jack C. Turner, Will J. Roper, Aswin P. Vijayan +5
RUBIES-UDS-QG-z7 (RQG) is the earliest massive quiescent galaxy identified to date, inferred to have formed its abundant stellar mass in a single burst that ceases rapidly before $…
