The shadow of the Ellis-Bronnikov wormhole and its throat silhouette

In this paper, we consider two possibilities for observing wormholes: obtaining an image of the shadow of a wormhole and obtaining an image of its throat. The shadow will be visible when the observer and the wormhole are surrounded by a glowing background. The throat of a wormhole is invisible, but its silhouette can be obtained if we assume that a lot of glowing probes fall on the wormhole, and the observer registers the signals that the probes emit on the throat. In this article, we obtain an expression for the silhouette radius of the Ellis-Bronnikov wormhole throat and compare it with the radius of the wormhole shadow.
