Title Probing the Accretion Timescales in Tidal Disruption Events with ZTF and XMM

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.
