| Abstract | The Zwicky Transient Facility (ZTF) is on track to transform the field of tidaldisruption 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 assemblinga large sample of TDEs, the nature of the optical emission remains a mystery,and appears to be distinct from the soft X-ray component (kT~50 eV) associatedwith 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 showdramatic variability that is totally decoupled from the smoothly evolvingoptical emission. Here propose for a program in AO-20 in order to create alegacy sample for X-ray population studies of TDEs for the first time. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
