    Main Research Fields

    I am an X-ray astronomer, focusing on transient events and the physics of extreme accretion.

    My work focuses on studying the possible link between two specific types of transient events: Tidal Disruption Events (TDEs – a bright burst of light when a star is destroyed around a black hole), and Quasi-Periodic Eruptions (QPEs – very rare repeated hour-long flares of soft X-rays, yet to be explained). Only a handful of QPEs are known, and some of them were seen in the late stages of TDEs, suggesting a possible link between these two phenomena.

    My approach to this problem is observation-based: by increasing the available sample of both phenomena, we will be better able to constrain the current models. To do this, I develop new more sensitive pipelines for X-ray data in order to detect new, otherwise missed transient events. These pipelines focus on long-term events (several years) and short term event (a few seconds), opening new windows to the high energy universe.
