Description
X-ray quasi-periodic eruptions (QPEs) are a recently discovered phenomenon associated with supermassive black holes at the centers of galaxies. They are high-amplitude soft X-ray flares that recur on timescales of hours, but what causes these flares remains uncertain. In this talk, I will review the history in discovering the QPE phenomenon and its possible origins, especially the difference between QPEs claimed in literature. In addition, I will report the discovery of a long-lasting Compton echo in a TDE candidate, which allows for constraining the distribution and physical conditions of circumnuclear gas, such as those in torus.
