Holographic image features of Hayward-AdS black hole surrounded by quintessence dark energy

Abstract

By employing the AdS/CFT correspondence, we investigate the holographic images of Hayward-AdS black hole enveloped by quintessence dark energy. The AdS boundary is equipped with a Gaussian oscillation source, which give rise to the response generated on the opposing side of the boundary after it propagated in the bulk. With the aid of a special wave optics system, the holographic images of black hole in the bulk can be constructed. When the observation position is located at the north pole of boundary, the virtual screen displays a sequence of closed concentric ring structures. There is invariably one of these rings consistently marked by an exceptionally high level of observational intensity, namely the holographic Einstein ring, which corresponds to the position of photon ring in the geometric optics. For other observation positions, the ring transforms gradually into a luminous arc-like shape and ultimately into a light spot positioned on the screen. And, the effects of the relevant state parameters on the characteristics of black hole holographic image, including the observed intensity, width or size of the ring, and proportion range, are in-depth examined. It is believed that the critical information of the Hayward-AdS black hole surrounded by quintessence can be obtained from these holographic images, which will help us understand the geometric characteristics of regular spacetime more deeply.
