TDE Schematic Diagram (IMAGE) University of California - Santa Cruz Caption A model of ultraviolet and optical emission from the tidal disruption event AT 2018hyz is shown in this schematic diagram. As an accretion disk forms quickly after the TDE, it generates x-ray emission (black arrows) at small radii, which is only visible through the vertical funnel. In other directions, x-rays are reprocessed by the photosphere or wind, powering the ultraviolet and optical emissions. Hydrogen emission is produced at two distinct sites outside of the photosphere: a large elliptical disk (color-coded by velocity to show rotation) joined by the fallback material, and a broad emission line region (BLR) that is likely created by a radiation-driven wind (purple shaded area).
