Gaia Photometric Science Alerts Data Flow

The Gaia Photometric Science Alerts project started operations in 2014 and will continue until 2020, with the goal of discovering transient events in the Gaia data. Since the mission began, more than 6000 transients have been discovered or had their existence confirmed. The data is received from the spacecraft and processed by the Alerts pipeline and flows through different web applications for selecting and publishing the transient alerts. After the publication of the findings, the Gaia Marshall web application serves as a meeting point for astronomers to interact for prioritizing and optimizing the follow-up and classification of the alerts.

This paper is a brief overview of the Gaia Photometric Science Alerts data flow, from the alert candidate extraction to their follow-up and classification.
