Dark and bright sides of the Broad Line Region clouds as seen in the FeII emission of SDSS RM 102
Alberto Floris, Ashwani Pandey, Bozena Czerny +4
Contamination from singly ionized iron emission is one of the greatest obstacles to determining the intensity of emission lines in the UV and optical wavelength ranges. This study…
Exploring the links between quasar winds and radio emission along the Main Sequence at high redshift
A. Deconto-Machado, A. del Olmo, P. Marziani
Despite the increasing prevalence of RL sources at cosmic noon, our understanding of the underlying physics that governs the accretion disc outflows in these particular sources and…
The extremes of AGN variability: outbursts, deep fades, changing looks, exceptional spectral states, and semi-periodicities
S. Komossa, D. Grupe, P. Marziani +16
The extremes of Active Galactic Nuclei (AGN) variability offer valuable new insights into the drivers and physics of AGN. We discuss some of the most extreme cases of AGN variabili…
Chemical abundances along the quasar main sequence
A. Floris, P. Marziani, S. Panda +5
The 4D eigenvector 1 (E1) sequence has emerged as a powerful tool for organizing the observational and physical characteristics of type-1 active galactic nuclei (AGNs). In this stu…
The power of relativistic jets: a comparative study
Luigi Foschini, Benedetta Dalla Barba, Merja Tornikoski +7
We present the results of a comparison between different methods to estimate the power of relativistic jets from active galactic nuclei (AGN). We selected a sample of 32 objects (2…
The Quasar 3C 47: Extreme Population B Jetted Source With Double-peaked Profile
Shimeles Terefe Mengistue, Paola Marziani, Ascensión del Olmo +3
Context. An optically thick, geometrically thin accretion disk (AD) around a supermassive black hole might contribute to broad-line emission in type-1 active galactic nuclei (AGN).…
From sub-solar to super-solar chemical abundances along the quasar main sequence
Paola Marziani, Alberto Floris, Alice Deconto-Machado +8
The 4D Eigenvector 1 sequence has proven to be a highly effective tool for organizing observational and physical properties of type 1 active galactic nuclei (AGN). In this paper, w…
