| Abstract | We propose to conduct deep X-ray observations of 12 nearby tidal disruptionevents (TDEs). This sample, selected from the first three years of the ZwickyTransient Facility operation, has good temporal coverage of early-time X-raydata. The proposed observations will be the first experiment to systematicallystudy the X-ray emission of optically bright TDEs at the time when the accretionis expected to transition from super-Eddington to sub-Eddington. This programwill help us to (1) investigate the timescale of delayed X-ray brightening, (2)explore the existence of disk corona and the efficiency of Comptonization, (3)measure the mass accretion rate, which directly tracks the mass fall-back rateat late 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. |
