Chapter 39: Transient Event Notification with VOEvent

Abstract

Events and transients are becoming more and more important in modern astronomy, for example gamma-ray bursts, supernovae, microlensing, and so on. We present the VOEvent infrastructure, for communicating observations of immediate astronomical events with the intention of stimulating rapid and automated follow up from robotic telescopes. The information packet itself will be described, as well as the emerging network that allows authoring, publication, subscription, and global identifiers. VOEvent is a general, standard, flexible, peer-to-peer, robust, secure, scalable solution for this infrastructure: a vision of multiple federated event streams shared by peers and evaluated by decision support.
