Explore a 31-minute conference talk from the Workshop on "Lensing and Wave Optics in Strong Gravity" that delves into the study of observable images from thin accretion disks surrounding rotating hairy black holes with time-periodic scalar fields. Learn how these alternative black holes differ from Kerr black holes through their complex geodesic structure and accretion disk formations. Discover the impact of varying scalar hair quantities on direct and indirect disk images, from chaotic patterns with multiple disconnected components at high charges near the boson star limit, to more organized structures with central dark regions at moderate charges, and finally to Kerr-like appearances at lower charges. Presented at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI) during their December 2024 workshop.
