| Abstract | The Zwicky Transient Facility (ZTF) is poised to produce the first statisticallysignificant sample of tidal disruption events (TDEs) from a single survey.However, despite this exciting progress in assembling large samples of TDEs, thenature of their optical emission remains a mystery. One of the physical modelsthat is gaining ground is that the optical component originates from alarger-scale structure associated with stream-stream collisions of the boundstellar debris, distinct from the newly formed debris disk powering the softX-ray emission. With this XMM-Newton program, we aim to test this model bymeasuring the evolution of the optical to X-ray ratio for a large sample of TDEsdiscovered promptly after disruption 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. |
