Description | ZTF has enabled the discovery of a new class of LINERs turning on into AGN with dramatic optical spectroscopic transformations. For the most rapid transition into a NLS1, real-time monitoring revealed the presence of a prominent soft excess and a luminous X-ray flare delayed with respect to the optical rise by 2 months. The proposed program will test physical mechanisms driving this new class of changing-look LINERs with joint XMM/NuSTAR observations by measuring the response of the reprocessed hard X-ray continuum in these nine objects. We wish to map out the structure of the accretion flow state change, view for the first time this new class of changing-look LINERs in the hard X-rays, and contrast their spectral properties with that of broad line and changing-look Seyferts. |

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. |
