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…
The stratified disk wind of MCG-03-58-007
V. Braito, J. N. Reeves, P. Severgnini +6
Past Suzaku, XMM and NuSTAR observations of the nearby (z=0.0323) bright Seyfert 2 galaxy MCG-03-58-007 revealed the presence of two deep and blue-shifted Fe K-shell absorption lin…
Lunar Gravitational-Wave Antenna
Jan Harms, Filippo Ambrosino, Lorella Angelini +51
Monitoring of vibrational eigenmodes of an elastic body excited by gravitational waves was one of the first concepts proposed for the detection of gravitational waves. At laborator…
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…
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…
