Transient outbursts and quasi-periodic eruption in the central galaxy

Abstract: 

In recent years, with the advancement of sky survey projects, an increasing number of transient sources have been discovered, including tidal disruption events (TDEs). These discoveries provide excellent opportunities to study black holes at the centers of galaxies. Recently, we have conducted extensive multi-wavelength observations of the early evolution of TDEs and discovered new phenomena. These observations provide valuable data for studying the dynamical processes and radiation mechanisms of such events. Additionally, as research has progressed, quasi-periodic eruption (QPE) signals have also been detected in the centers of galaxies, though their physical origin remains unclear. In this talk, I will present our recent findings from multi-wavelength, high-cadence observations in the TDE. Furthermore, I will also introduce our new discoveries in the research of QPEs.
