Modelling the variable emission states of $\gamma$-ray emitting Narrow-Line Seyfert 1 galaxies

Anna Luashvili, Catherine Boisson, Andreas Zech +2

$\gamma$-ray-emitting narrow-line Seyfert 1 galaxies ($\gamma$-NLS1) constitute an intriguing small population of Active Galactic Nuclei with $\gamma$-ray emission resembling low power flat-spect…
