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…
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 observati…
SN 2016iog: A fast declining Type II-L supernova with an ultra-faint tail, persistently interacting with circumstellar material
Z. -H. Peng, S. Benetti, Y. -Z. Cai +26
We present optical photometric and spectroscopic observations of the rapidly declining Type IIL supernova (SN) 2016iog. SN 2016iog reached its peak 14 days after explosion,…
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…
SN 2018is: a low-luminosity Type IIP supernova with narrow hydrogen emission lines at early phases
R. Dastidar, K. Misra, S. Valenti +31
We present a comprehensive photometric and spectroscopic study of the Type IIP SN 2018is. The -band luminosity and the expansion velocity at 50 days post-explosion are 15.1$\…
A host galaxy study of southern narrow-line Seyfert 1 galaxies
I. Varglund, E. Järvelä, S. Ciroi +4
We studied seven nearby narrow-line Seyfert 1 (NLS1) galaxies in - and -bands with redshifts varying from 0.019 to 0.092. This is the first multi-source study targeting the…
