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

Description The Zwicky Transient Facility (ZTF) is on track to produce the first statistically significant sample of tidal disruption events (TDEs) from a single survey, with a projection of virgul100 TDEs discovered over the 3 year survey. This ZTF TDE sample will enable a robust measurement of the TDE rate, and a mapping of TDE light curves to physical parameters such as central black hole mass. However, the nature of the optical emission remains a mystery, and appears to be distinct from the soft X-ray component associated with the accretion of the stellar debris through a newly formed disk. We propose to continue our successful AO-17 XMM-Newton follow-up program for ZTF TDEs, in order to measure evolution of the optical to X-ray for a large sample of TDEs discovered promptly after disruption.

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.
