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