Description
Eintein Probe (EP) is a space X-ray observatory to monitor the soft X-ray sky with X-ray follow-up capability, and was lauched on January 9, 2024. It carried out a series of performance verification and calibration observation after launch and had begun scientific observations since late July. By now, EP has detected more than 30 fast X-ray transients, and long-term transients of different origin. Of which, some are very puzzling transients and their nature are still under investigation. In this talk, we will introduce the strategy we adopt to search for the transeints. For short term transients, like GRBs and stellar flares, that show high amplitude varibility during one single exposure, the Bayesian block algotithm is adopted to search for the variability signal. While for long-term, and relatively fainter transients, like TDEs, data stacking is used to increase the detection sensitivity. All these sources have been carefully identified following a series of cross-matches with astronomical data bases and multiwavelength catalogues, and also follow-up observations. In this talk, we will give a brief intriduction to the transient search and source identifications for EP, and also priliminary results of some peculiar EP transients.
