The Millimeter/X-ray Relation in Rapidly Accreting Supermassive Black Holes at

Sophie M. Venselaar, Claudio Ricci, Santiago Del Palacio +12

A tight correlation between nuclear millimeter and X-ray emission has recently been found in nearby () and low-Eddington ratio () radio-quiet Active Ga…

Multi-wavelength properties of changing-state active galactic nuclei: I. the evolution of soft excess and X-ray continuum

Arghajit Jana, Claudio Ricci, Alessia Tortosa +11

Changing-state active galactic nuclei (CSAGNs) exhibit rapid variability, with mass accretion rates that can change by several orders of magnitude in a few years. This provides us…

BASS XLI: the correlation between Mid-infrared emission lines and Active Galactic Nuclei emission

M. Bierschenk, C. Ricci, M. J. Temple +22

We analyze the Spitzer spectra of 140 active galactic nuclei (AGN) detected in the hard X-rays (14-195 keV) by the Burst Alert Telescope (BAT) on board Swift. This sample allows us…

BASS XLII: The relation between the covering factor of dusty gas and the Eddington ratio in nearby active galactic nuclei

C. Ricci, K. Ichikawa, M. Stalevski +25

Accreting supermassive black holes (SMBHs) located at the center of galaxies are typically surrounded by large quantities of gas and dust. The structure and evolution of this circu…

Ray-tracing simulations of the Soft X-ray Scattered Emission in obscured Active Galactic Nuclei

Jeffrey McKaig, Claudio Ricci, Stéphane Paltani +3

Most Active Galactic Nuclei (AGN) in the local Universe are obscured. In these obscured AGN an excess is usually observed in the soft X-rays below ~2 keV above the absorbed X-ray c…
