TransientVerse: A comprehensive real-time alert and multiwavelength analysis system for transient astronomical events

Transient astrophysical events, characterized by short timescales and high-energy radiation, are a key focus of modern astronomy. However, current transient alert systems face challenges, including the distribution of alerts across multiple platforms and inconsistencies in formatting, which hinder the efficient coordination of follow-up observations in multiwavelength and multi-messenger astronomy. This paper presents TransientVerse, an innovative platform designed to integrate and disseminate transient event alerts. The platform integrates an automated ingestion pipeline that aggregates alerts from multiple platforms (e.g., Astronomer’s Telegram (ATel), the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Fast Radio Burst (FRB) Virtual Observatory Event (VOEvent), and the General Coordinates Network (GCN)). It uses large language models to extract structured information from unstructured alerts, storing both forms in separate databases to support efficient tracking and analysis. TransientVerse offers retrospective searches, data visualization, literature integration and linking, and interactive tools for efficient event tracking and follow-up. For repeating FRBs, the platform generates visualized sky maps and detection statistics from CHIME/FRB VOEvent messages, enabling time-range filtering, coordinate switching, and source ranking by burst frequency to support follow-up planning. TransientVerse improves the efficiency of real-time transient event acquisition, lowers the technical barriers for coordinated observations, and provides robust support for multiwavelength and multi-messenger time-domain astronomy, thereby facilitating astrophysics research.
