A possible sub-kiloparsec dual AGN buried behind the galaxy curtain
P. Severgnini, V. Braito, C. Cicone +11
Although thousands of galaxy mergers are known, only a handful of sub-kiloparsec-scale supermassive black hole (SMBH) pairs have been confirmed so far, leaving a huge gap between t…
Unveiling sub-parsec supermassive black hole binary candidates in active galactic nuclei
Roberto Serafinelli, Paola Severgnini, Valentina Braito +11
Elusive supermassive black hole binaries (SMBHBs) are thought to be the penultimate stage of galaxy mergers, preceding a final coalescence phase. SMBHBs are sources of continuous g…
Probing the circumnuclear absorbing medium of the buried AGN in NGC 1068 through NuSTAR observations
A. Zaino, S. Bianchi, A. Marinucci +9
We present the results of the latest NuSTAR monitoring campaign of the Compton-thick Seyfert 2 galaxy NGC 1068, composed of four 50 ks observations performed between July 201…
A broadband X-ray view of the NLSy1 1E 0754.6+392.8
R. Middei, F. Tombesi, F. Vagnetti +8
The soft X-ray band of many active galactic nuclei (AGNs) is affected by obscuration due to partially ionised matter crossing our line of sight. In this context, two past XMM-Newto…
