Title XMM Follow-Up of Tidal DIsruption Events in ZTF: Building a Legacy Sample


DOI https://doi.org/esa-[xxxxxxx]
Author Dr Suvi Gezari
Description The Zwicky Transient Facility (ZTF) is on track to transform the field of tidal disruption events (TDEs). In the first 2.5 yr of ZTF survey operations (ZTF-I), we have detected 25 TDEs. However, despite this exciting progress in assembling a large sample of TDEs, the nature of the optical emission remains a mystery, and appears to be distinct from the soft X-ray component (kTvirgul50 eV) associated with the accretion of the stellar debris through a newly formed disk. In fact, with our X-ray follow-up observations we have revealed that the soft X-rays show dramatic variability that is totally decoupled from the smoothly evolving optical emission. Here propose for a program in AO-20 in order to create a legacy sample for X-ray population studies of TDEs for the first time.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
