The Mini-SiTian Array: Prospects of Searching for Tidal Disruption Events
Abstract We assess the detectability of tidal disruption events (TDEs) using mock observations from the Mini-SiTian Array. We select 100 host galaxy samples from a simulated galaxy catalog based on specific criteria such as redshift, black hole mass, and event rate. Taking into account the site conditions and survey strategy, we simulate observations over a 440 deg 2 field. The results indicate that 0.53 ± 0.73 TDEs can be detected per year when observing in both g and r bands with 300 s exposures every 3 days. Applying this method to the SiTian project, we expect to discover approximately 204 TDEs annually, heralding a new era in TDE science.
