Super-Eddington Accretion and Early-Stage Feedback in Ton S180
Pierpaolo Condò, Giacomo Venturi, Eleonora Parlanti +15
Narrow-line Seyfert 1 (NLSy1) galaxies are key laboratories for studying rapid supermassive black hole (SMBH) growth and active galactic nucleus (AGN) feedback at high accretion ra…
Flagging Super-Eddington Candidates among Jetted, γ-Ray-Emitting AGN
Paola Marziani, Benedetta Dalla Barba, Luigi Foschini
The quasar Eigenvector-1/Main Sequence (E1/MS) provides a physically motivated empirical framework to organize the spectroscopic diversity of type~1 active galactic nuclei (AGN). I…
An X-ray and optical spectral study of the changing-look narrow-line Seyfert 1 2MASX J0413-0050
A. Vietri, A. Tortosa, D. Ilić +12
Active galactic nuclei (AGN) showing dramatic spectral and flux variations, either due to changes in the accretion rate (changing-state, CS-AGN) of the supermassive black hole or i…
Revised optical classification of a sample of gamma-ray emitting AGN with GTC and VLT
B. Dalla Barba, L. Foschini, M. Berton +10
We report the results of the optical follow-up of a sample of -ray-emitting active galactic nuclei (AGN). New high-quality optical spectra were obtained using Gran Telescopio Ca…
Interaction of the relativistic jet and the narrow-line region of PMN J0948+0022
B. Dalla Barba, M. Berton, L. Foschini +6
We have analyzed publicly available optical spectra of PMN J0948+0022 obtained with the Sloan Digital Sky Survey, X-Shooter, and the Multi Unit Spectroscopic Explorer (MUSE). Initi…
An optical perspective on early-stage AGN with extreme radio flares
Luca Crepaldi, Marco Berton, Benedetta Dalla Barba +4
In the last decade of Active Galactic Nuclei (AGN) monitoring programs, the Metsähovi Radio Observatory detected multiple times seven powerful flaring narrow-line Seyfert 1 (NLS1)…
Estimating Masses of Supermassive Black Holes in Active Galactic Nuclei from the Halpha Emission Line
E. Dalla Bontà, B. M. Peterson, C. J. Grier +19
The goal of this project is to construct an estimator for the masses of supermassive black holes in active galactic nuclei (AGNs) based on the broad Halpha emission line. We make u…
Quasi-periodic X-ray eruptions and tidal disruption events prefer similar host galaxies
T. Wevers, K. D. French, A. I. Zabludoff +10
In the past five years, six quasi-periodic X-ray eruption (QPE) sources have been discovered in the nuclei of nearby galaxies. Their origin remains an open question. We present MUS…
The host galaxy of low-luminosity compact sources
A. Vietri, M. Berton, E. Järvelä +6
The term 'active galactic nuclei' (AGN) subtends a huge variety of objects, classified on their properties at different wavelengths. Peaked sources (PS) represent a class of AGN at…
