Transient obscuration event captured in NGC 3227. I. Continuum model for the broadband spectral energy distribution
M. Mehdipour, G. A. Kriss, J. S. Kaastra +21
From Swift monitoring of a sample of active galactic nuclei (AGN) we found a transient X-ray obscuration event in Seyfert-1 galaxy NGC 3227, and thus triggered our joint XMM-Newton…
