| ABSTRACT | |
| SDSS-V, currently ramping up to full operation, will obtain repeated optical spectroscopy for thousands of AGN. This will allow for the optical identification of currently transitioning changing-look AGN. We request 6 ToOs using XMM-Newton and Swift to follow the X-ray and UV evolution of the ongoing optical transition. XMM-Newton will deliver X-ray spectra in its visibility windows, while Swift provides X-ray flux constraints in the time between. The obtained X-ray, UV, and optical datasets will explore how the X-ray corona, accretion disc, and broad-emission line region interact with each other. It will deliver valuable insights into how accretion flows evolve during AGN ignitions and depletions. We will compare our results with the outcomes of a program on X-ray-selected changing-look AGN. | |
