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…
Elucidating the global distribution of reprocessing gas in NGC 1194
T. J. Turner, J. N. Reeves, V. Braito +3
A joint XMM-Newton and NuSTAR observation was conducted for the bright, local Seyfert 1.9 galaxy, NGC 1194. The hard spectral form of this AGN was modeled using the toroidal reproc…
The first blazar observed at z>6
S. Belladitta, A. Moretti, A. Caccianiga +9
We present the discovery of PSO J030947.49+271757.31, the radio brightest (23.7 mJy at 1.4 GHz) active galactic nucleus (AGN) at z>6.0. It was selected by cross-matching the NRAO V…
