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.

The evolution of galaxy dust scaling relations in the COLIBRE simulations

Aswin P. Vijayan, James W. Trayford, Joop Schaye +11

The paper uses the COLIBRE cosmological simulations to study how dust mass, composition, and grain sizes in galaxies evolve from the early Universe to the present, comparing predic…

The COLIBRE-SKIRT pipeline: Calibration-free dust radiative transfer postprocessing for cosmological simulations

Andrea Gebek, Maarten Baes, Nick Andreadis +16

The paper introduces the COLIBRE‑SKIRT pipeline, a calibration‑free method that uses the SKIRT radiative transfer code to generate multi‑wavelength mock observations from large‑vol…

Origins of Extreme Emission-Line Ratios in z > 3 Galaxies: Insights from the Lumen Model

Lucie Scharré, Michaela Hirschmann, Adèle Plat +10

Optical emission-line ratios in star-forming galaxies at -8, such as [OIII]/H and [OIII]/[OII], are strongly offset from those at -2, pointing to more extre…
