MUSE adaptive-optics spectroscopy confirms dual active galactic nuclei and strongly lensed systems at sub-arcsec separation
The novel Gaia multi peak (GMP) technique has proven to be able to successfully select
dual and lensed active galactic nuclei (AGN) candidates at sub-arcsecond separations. Both …

Dual Active Galactic Nuclei: Precursors of Binary Supermassive Black Hole Formation and Mergers
The presence of dual active galactic nuclei (AGNs) on scales of a few tens of kiloparsecs
can be used to study merger-induced accretion on supermassive black holes (SMBHs) and …

A surprisingly high number of dual active galactic nuclei in the early Universe
Merger events can trigger gas accretion onto supermassive black holes (SMBHs) sitting at
the centre of galaxies, and form close pairs of active galactic nuclei (AGN). The fraction of …
