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…
No evolution in the number density of little red dots from cosmic dawn to cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +24
We present our search for little red dots (LRDs) in the "J1030 field", a region of the sky around the quasar SDSS J1030+0524, observed by the JWST EIGER program. Over 1…
Dual AGN and Multiple SMBH Systems in the Era of SKAO
Q. D'Amato, L. Cui, R. Deane +23
We present a radio-oriented review of current strategies for the detection and characterization of dual active galactic nuclei (DAGN) and supermassive black hole binaries (SMBHBs),…
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…
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…
Cosmic Duets I. High-spatial resolution spectroscopy of dual and lensed AGN with MUSE-NFM
M. Scialpi, F. Mannucci, Q. D'Amato +34
We present the first-year results of the MUSE Large Program "Cosmic Duets", whose goal is to obtain adaptive-optics assisted MUSE observations with an angular resolution of 0.1"-0.…
