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…
How similar are narrow-line Seyfert 1 galaxies and high-z type 1 AGN?
Marco Berton, Emilia Järvelä, Alessia Tortosa +1
The recent observations of highly accreting supermassive black holes (SMBH) at very high redshift (4) with the James Webb Space Telescope (\textit{JWST}) allowed us to shed lig…
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)…
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…
X-ray properties of two complementary samples of intermediate Seyfert galaxies
Benedetta Dalla Barba, Luigi Foschini, Marco Berton +2
We present the X-ray spectral analysis of two complementary sets of intermediate Seyfert galaxies (ISs). Analyzing X-ray data, we estimate the hydrogen abundance and test its…
Intra-night optical variability of peculiar narrow-line Seyfert 1 galaxies with enigmatic jet behavior
Vineet Ojha, Veeresh Singh, M. Berton +1
Variability studies of active galactic nuclei are a powerful diagnostic tool in understanding the physical processes occurring in disk-jet regions, unresolved by direct imaging wit…
