| Description | We propose to conduct deep X-ray observations of 12 nearby tidal disruption events (TDEs). This sample, selected from the first three years of the Zwicky Transient Facility operation, has good temporal coverage of early-time X-ray data. The proposed observations will be the first experiment to systematically study the X-ray emission of optically bright TDEs at the time when the accretion is expected to transition from super-Eddington to sub-Eddington. This program will 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 rate at late 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. |
