NOCTURNE. I. The radio spectrum of narrow-line Seyfert 1 galaxies
M. Berton, E. Järvelä, S. Chen +8
The origin of the radio emission in active galactic nuclei (AGN) is still debated. Multiple physical mechanisms can contribute to the spectrum at these frequencies, including relat…
Insights into jet-NLR energetics in PMN J0948+0022
B. Dalla Barba, L. Foschini, M. Berton +8
The analysis of the optical spectra of PMN J0948+0022 showed significant variations in the spectral lines that, when combined with the Fermi -ray light curve and radio observat…
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 C…
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…
Estimating Masses of Supermassive Black Holes in Active Galactic Nuclei from the Halpha Emission Line
E. Dalla BontÃ, 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…
