Searching for signatures of fuzzy dark matter in cosmic filament profiles
Callum J. O'Kane, Alfonso Aragón-Salamanca, Ulrike Kuchner +1
Current observations reveal persistent tensions with the standard cold dark matter paradigm, raising the question of whether these can be explained by baryonic physics alone or req…
Identifying group galaxies merging with massive clusters using machine learning
Rhys Jordan, Meghan E. Gray, Alfonso Aragón-Salamanca +3
The environment plays a critical role in galaxy evolution, with galaxy clusters and their infall regions offering diverse conditions that shape galaxies before they enter the dense…
Where have all the low-metallicity galaxies gone? Tracing evolution in the mass--metallicity plane since a redshift of 0.7
Shuang Zhou, Alfonso Aragón-Salamanca, Michael Merrifield +1
Even over relatively recent epochs, galaxies have evolved significantly in their location in the mass-metallicity plane, which must be telling us something about the latter stages…
The localization of galaxy groups in close proximity to galaxy clusters using cosmic web nodes
Daniel J. Cornwell, Ulrike Kuchner, Meghan E. Gray +4
We investigate the efficacy of using the cosmic web nodes identified by the DisPerSE topological filament finder to systematically identify galaxy groups in the infall regions arou…
