Unveiling the properties of galaxy cores excavated by supermassive black hole binaries with SHARP
E. Bortolas, E. Portaluri, E. Dalla Bonta' +3
Massive black hole (MBH) binaries form as a result of galaxy mergers and can coalesce into a single MBH by emitting gravitational waves detectable by LISA and pulsar timing array c…
A new era for Dual AGN science with SHARP
P. Severgnini, C. Vignali, A. De Rosa +21
The search for and the characterization of ultra-compact dual active galactic nuclei (AGN) are among the hottest topics of current extragalactic astrophysics. These systems involve…
Enhanced activity in close dual-AGN systems in the local Universe
Lorenzo Battistini, Alessandra De Rosa, Paola Severgnini +16
We present the study of an X-ray selected sample of active galactic nuclei (AGN) in pairs at projected spatial separations 1 </kpc < 100 at z < 0.1, using XMM-Newton and Chan…
Higher resolution optical spectra of galaxies reveal outflow signatures unresolved by the SDSS
B. Hagedorn, C. Cicone, C. Vignali +5
Galactic outflows are predicted to be ubiquitous in low-mass galaxies, but observational evidence is lacking. Both a low signal-to-noise and a low spectral resolution can severely…
A XRISM view of the iron line complex in NGC 1068: Rethinking the prototypical Compton-thick AGN
S. Bianchi, B. Vander Meulen, E. Bertola +32
We analyze a XRISM/Resolve observation of NGC1068, focusing on the Fe K and Fe K fluorescent lines and on the Fe XXV and Fe XXVI emission complexes. Line centroid energies, i…
Fast, dust-poor outflows in the local candidate dual AGN MCG-03-34-64 observed with VLT/ERIS
I. Lamperti, F. Mannucci, E. Bertola +28
We present VLT/ERIS IFU J-band observations of MCG-03-34-64, a nearby (z = 0.0167) Seyfert galaxy hosting a candidate dual AGN system with a separation of ~100 pc between the nucle…
