Abstract NGC 3516 is a remarkable Seyfert-1 galaxy, which over the last decade hasundergone major spectral transformations, classifying it as a changing-look AGN.Understanding the nature and origin of spectral variability in suchchanging-look AGN would provide key insights into the accretion-outflowmechanism. Swift monitoring of NGC 3516 shows dramatic flux rises and declinesduring its changing-look state. We propose ToO observations with XMM, NuSTAR,and HST, triggered using Swift monitoring, to catch NGC 3516 at a high fluxlevel to be able to carry out the first high resolution X-ray and UVspectroscopy of its winds during the changing-look state. The proposedobservations would enable us to ascertain the role of winds in the transformation of NGC 3516.

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.
