Description The Zwicky Transient Facility (ZTF) is poised to produce the first statistically significant sample of tidal disruption events (TDEs) from a single survey. However, despite this exciting progress in assembling large samples of TDEs, the nature of their optical emission remains a mystery. One of the physical models that is gaining ground is that the optical component originates from a larger-scale structure associated with stream-stream collisions of the bound stellar debris, distinct from the newly formed debris disk powering the soft X-ray emission. With this XMM-Newton program, we aim to test this model by measuring the evolution of the optical to X-ray ratio for a large sample of TDEs discovered promptly after disruption 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.
