Hot Gas, Cold Gas, and Stars: Mapping the Halo Baryon Budget in the Local Universe

Feedback processes, particularly from active galactic nuclei (AGN), play a crucial role in redistributing baryons within dark matter halos. These mechanisms can displace gas to halo outskirts or eject it entirely, resulting in baryon fractions significantly below the cosmic mean—especially in low-mass systems where...

Forward-modelling galaxy surveys for next-generation cosmological and galaxy population measurements

We are entering a transformative era for cosmology and galaxy evolution, driven by wide-field photometric and spectroscopic galaxy surveys that will map a significant fraction of the observable Universe at an unprecedented volume and depth. These surveys will measure positions, magnitude, and...
