We propose to observe the local (z=0.00842) Seyfert 2 galaxy NGC 4388simultaneously with NuSTAR and XMM-Newton for 50 ks and 60 ks, respectively, inorder to obtain conclusive evidence on the physical nature of the circumnuclearmatter in this source. NGC 4388 has been already observed by many X-rayobservatories highlighting several peculiar properties. In particular, in 2005Suzaku observed a prominent Fe KI? line (EWa??200 eV) and a significantcontribution of the reflection component (R = 1.40+0.29-0.36), while in 2013NuSTAR revealed a very weak Compton hump (R<0.09) and a very large iron KI? lineEW (368+56 eV with respect to the intrinsic continuum) for a source with weak orno reflection.

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.
