A multiwavelength characterization of the obscuring medium at the center of NGC 6300 Open
Most of the supermassive black holes in the Universe accrete material in an obscured phase. While it is commonly accepted that the “dusty torus” is responsible for the nuclear obscuration, its geometrical, physical, and chemical properties…

Fast supermassive black hole growth in the SPT2349–56 protocluster at <i>z</i> = 4.3 Open
Context. Large-scale environment is one of the main physical drivers of galaxy evolution. The densest regions at high redshifts (i.e. z > 2 protoclusters) are gas-rich regions characterised by high star formation activity. The same physica…

Fast SMBH growth in the SPT2349--56 protocluster at $z=4.3$ Open
Protoclusters at $z>2$ are gas-rich regions characterized by high star-formation activity. The same physical properties that enhance star formation in protoclusters are also thought to boost the growth of SMBHs. We aim to test this scenari…

A post-merger enhancement only in star-forming Type 2 Seyfert galaxies: the deep learning view Open
Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major mergers have the ability to drive gas rapidly inwards, but observations trying…

Probing the roles of orientation and multiscale gas distributions in shaping the obscuration of active galactic nuclei through cosmic time Open
The origin of obscuration in active galactic nuclei (AGNs) is still an open debate. In particular, it is unclear what drives the relative contributions to the line-of-sight column densities from galaxy-scale and torus-linked obscuration. T…

In the standard quasar model, the accretion disc obscuration is due to the canonical dusty torus. Here, we argue that a substantial part of the quasar obscuration can come from the interstellar medium (ISM) when the quasars are embedded in…
