| Description | We propose deep late-time observations with XMM-Newton of two of the nearest known superluminous supernovae (SLSNe), 2017egm and 2016eay, to perform a focused test of the popular model for the power source of hydrogen-poor SLSNe that relies on the spindown energy of rapidly rotating newly born magnetars. Our previous late-time observation of the SLSN 2015bn with XMM-Newton resulted in a non-detection, indicating that less than 2% of the inferred spindown energy of the magnetar was being emitted at UVOIR or X-ray wavelengths at late times, identifying a missing energy problem. We seek to test whether this is a generic problem by performing late-time XMM-Newton observations of these two objects by measuring the luminosity of X-rays escaping the ejecta at ages of 2-3 years. |

| 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. |
