MUSE adaptive-optics spectroscopy confirms dual active galactic nuclei and strongly lensed systems at sub-arcsec separation
M. Scialpi, F. Mannucci, C. Marconcini +21
The novel Gaia Multi Peak (GMP) technique has proven to be able to successfully select dual and lensed AGN candidates at sub-arcsec separations. Both populations are important beca…

Extinction and AGN over host galaxy contrast effects on the optical spectroscopic classification of AGN
L. BarquÃn-González, S. Mateos, F. J. Carrera +9
The optical spectroscopic classification of active galactic nuclei (AGN) into type 1 and type 2 can be understood in the frame of the AGN unification models. However, it remains un…
