Unveiling the correlation between the UV 2175 Å dust attenuation bump, PAH emission, and gas-phase metallicity at cosmic noon

L. Arriscado, I. Shivaei, L. A. Boogaard +17

The UV 2175 Å attenuation bump is one of the most prominent yet poorly understood features of galaxy attenuation curves. Its main candidate carrier is polycyclic aromatic hydrocarb…
