| 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. |
