| Description | X-ray quasi-periodic eruptions (QPEs) are a new phenomenon associated to non-stationary accretion onto supermassive black holes (SMBH) in low-mass galaxies. RX J1301.9+2747 (RX J1302) is one of the four galaxies where QPEs have been detected so far, and the only one with QPEs lasting for decades In addition, the QPEs display multiple patterns of quasi-periodicity which is a puzzling behavior never seen before. We ask for a two-orbits-long XMM-Newton observation of the galaxy RX J1302, coordinated with 20 hours of VLA radio exposures, to confirm the alternate pattern of variability between cold/long and warm/short QPEs, and explore the possible connections with the radio jet. |

| 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. |
