X-ray quasi-periodic eruptions (QPEs) are a new phenomenon associated tonon-stationary accretion onto supermassive black holes (SMBH) in low-massgalaxies. RX J1301.9+2747 (RX J1302) is one of the four galaxies where QPEs havebeen detected so far, and the only one with QPEs lasting for decades Inaddition, the QPEs display multiple patterns of quasi-periodicity which is apuzzling behavior never seen before. We ask for a two-orbits-long XMM-Newtonobservation of the galaxy RX J1302, coordinated with 20 hours of VLA radioexposures, to confirm the alternate pattern of variability between cold/long andwarm/short QPEs, and explore the possible connections with the radio jet.

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.
