DOI: 10.1051/0004-6361/202039576
Abstract: 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 the observed and predicted numbers of such objects.… read more here.

DOI: 10.1093/mnras/staf1928
Abstract: We present a structural analysis of bulges in dual active galactic nuclei (AGN) host galaxies. Dual AGN arise in galaxy mergers where both supermassive black holes (SMBHs) are actively accreting. The AGN are typically embedded… read more here.

DOI: 10.1093/mnras/stx1067
Abstract: We investigate the simultaneous triggering of active galactic nuclei (AGN) in merging galaxies, using a large suite of high-resolution hydrodynamical simulations. We compute dual-AGN observability time-scales using bolometric, X-ray and Eddington-ratio thresholds, confirming that dual… read more here.

DOI: 10.1093/mnras/sty3251
Abstract: We look into the abundance of Dual AGN (active galactic nucleus) in the largest hydrodynamical simulation from the Evolution and Assembly of GaLaxies and their Environment (EAGLE) project. We define a Dual AGN as two… read more here.

Searching for dual AGN in galaxies with double-peaked emission line spectra using radio observations

DOI: 10.1093/mnras/stz334
Abstract: Supermassive black hole (SMBH) binaries form due to galaxy mergers and minor accretion events. When the SMBHs are accreting, they form dual or binary AGN and can give rise to double-peaked emission lines in the… read more here.

DOI: 10.1093/mnrasl/slab106
Abstract: Dual-Active Galactic Nuclei (AGN) are a natural consequence of the hierarchical structure formation scenario, and can provide an important test of various models for black hole growth. However, due to their rarity and difficulty to… read more here.
