BURSTT: Bustling Universe Radio Survey Telescope in Taiwan

Fast Radio Bursts (FRBs) are bright millisecond-duration radio transients that appear about 1,000 times per day, all-sky, for a fluence threshold 5 Jy ms at 600 MHz. The FRB radio-emission physics and the compact objects involved in these events subjects of intense active debate. To better constrain source models, Bustling Universe Survey Telescope Taiwan (BURSTT) is optimized to discover localize large sample rare, high-fluence, nearby FRBs. This population most amenable multi-messenger, multi-wavelength follow-up, allowing deeper understanding mechanisms. BURSTT will provide horizon-to-horizon sky coverage with half power field-of-view (FoV) $\sim$10$^{4}$ deg$^{2}$, 400 MHz effective bandwidth between 300-800 MHz, sub-arcsecond localization, made possible using outrigger stations hundreds thousands km from main array. Initially, employ 256 antennas. After tests various antenna designs optimization system performance we plan expand 2048 We estimate BURSTT-256 detect $\sim$100 ($\geq$100 ms) FRBs year. Another advantage BURSTT's FoV continuous operation be greatly enhanced monitoring repetition. current lack sensitive all-sky observations likely means many repeating currently cataloged as single-event
