TL;DR
ANTARES is a software system that processes large streams of astronomical alerts, annotates and filters events, helping astronomers manage the increasing volume of time-domain data from modern telescopes.
Contribution
It introduces a scalable, flexible event broker architecture with advanced filtering, annotation, and provenance tracking for astronomical time-domain surveys.
Findings
Efficient processing of tens of thousands of alerts per night.
Customizable filtering and annotation capabilities.
Robust system performance and user interface.
Abstract
We describe the Arizona-NOIRLab Temporal Analysis and Response to Events System (ANTARES), a software instrument designed to process large-scale streams of astronomical time-domain alerts. With the advent of large-format CCDs on wide-field imaging telescopes, time-domain surveys now routinely discover tens of thousands of new events each night, more than can be evaluated by astronomers alone. The ANTARES event broker will process alerts, annotating them with catalog associations and filtering them to distinguish customizable subsets of events. We describe the data model of the system, the overall architecture, annotation, implementation of filters, system outputs, provenance tracking, system performance, and the user interface.
