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…

X-ray flashes from the low-mass X-ray binary IGR J17407-2808
L. Ducci, C. Malacaria, P. Romano +4
IGR J17407-2808 is an enigmatic and poorly studied X-ray binary that was recently observed quasi-simultaneously with NuSTAR and XMM-Newton. In this paper we report the results of t…

A redshifted excess in the broad emission lines after the flare of the -ray narrow-line Seyfert 1 PKS 2004-447
W. Hon, M. Berton, E. Sani +6
PKS 2004-447 is a narrow-line Seyfert 1 (NLS1) harbouring a relativistic jet with gamma-ray emission. On 2019-10-25, the Fermi-Large Area Telescope captured a -ray flare from th…
