Description
Fast Radio Bursts (FRBs) represent one of the most intriguing frontiers in modern astrophysics, yet their origins and physical mechanisms remain elusive. The Bustling Universe Radio Survey Telescope in Taiwan (BURSTT) project is a dedicated radio interferometer designed to address these fundamental challenges. By prioritizing an ultra-wide "fisheye" field of view, BURSTT compensates for its moderate sensitivity by focusing on a systematic census of bright, nearby FRBs (median redshift z ~ 0.04), which are prime targets for multi-wavelength and multi-messenger follow-up observations.
The project has successfully completed its first phase (2023–2026). The Fushan main station, featuring an upgraded wide-band (300–800 MHz) array of 256 Log-Periodic Dipole Antennas (LPDAs), operates in conjunction with outrigger stations in Nantou and Green Island to provide essential sub-arcsecond localization. Following successful system fine-tuning and the initiation of reliable FRB detections, we are now launching an ambitious expansion phase. This includes a fourfold increase in experimental capacity and the ongoing development of an international outrigger network, including stations in Jinmen, Ogasawara (Japan), and Pyeongchang (Korea). Furthermore, we are actively conducting site surveys and prototyping for additional international nodes in Hawaii, India, Vietnam, Thailand, and Mongolia. This presentation outlines the current operational status of the BURSTT infrastructure and our long-term roadmap to transform FRB science through high-cadence, wide-field monitoring.
