Abstract We propose an in-depth X-ray study of fast blue optical transients (FBOTs), anew class of transients with luminosities and time scales that challengetraditional SN models. Alternative scenarios include a failed SN of a strippedstar, He-shell detonation on a white dwarf, and a SN shock breaking through adense medium. FBOTs have mostly been studied in the optical/UV regime, which isof thermal origin and it is not sensitive to the nature of the underlying energysource. Here we propose to capitalize on our recent discovery of X-rays from theFBOT AT2018cow with unprecedented properties, and start the first broad-bandX-ray monitoring campaign of FBOTs. The primary goal is to test for the presenceof engines driving the explosions and constrain their nature.

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.
