Abstract
The 1.5 Seyfert galaxy, NGC 3516, presents a complex time variability in X-rays. We analysed the 2006 XMM-Newton and Chandra spectra in the band 0.3-10 keV. We found an acceptable fitting model which consists of a variable continuum emission absorbed by three ionized phases -warm absorbers- in outflow, with different ionization degrees. One of the absorption phases is responding to the continuum emission variability. We present our most oustanding results.
