Tracking the year-to-year variation in the spectral energy distribution of the Narrow-line Seyfert 1 Galaxy Mrk335
S. Tripathi, K. M. McGrath, L. C. Gallo +5
Multi-wavelength monitoring of Mrk 335 with Swift between 2007-2019 are used to construct annual spectral energy distributions and track year-to-year changes. Non-contemporaneous a…
Multi-epoch X-ray spectral analysis of the narrow-line Seyfert 1 galaxy Mrk 478
S. G. H. Waddell, L. C. Gallo, A. G. Gonzalez +2
A multi-epoch X-ray spectral and variability analysis is conducted for the narrow-line Seyfert 1 (NLS1) active galactic nucleus (AGN) Mrk 478. All available X-ray data from XMM-New…
The nature of the soft-excess and spectral variability in the Seyfert 1 galaxy Zw 229.015
S. Tripathi, S. G. H. Waddell, L. C. Gallo +2
We have carried out a systematic analysis of the nearby (z=0.0279) active galaxy Zw 229.015 using multi-epoch, multi-instrument and deep pointed observations with XMM-Newton, Suzak…
Investigating the origin of the Fe emission lines of the Seyfert 1 galaxy Mrk~205
Sibasish Laha, Ritesh Ghosh, Shruti Tripathi +1
We have investigated the nature and origin of the Fe K emission lines in Mrk~205 using observations with {\it Suzaku} and {\it XMM-Newton}, aiming to resolve the ambiguity between…
Evidence for an emerging disc wind and collimated outflow during an X-ray flare in the narrow-line Seyfert 1 galaxy Mrk 335
L. C. Gallo, A. G. Gonzalez, S. G. H. Waddell +13
A triggered 140 ks XMM-Newton observation of the narrow-line Seyfert 1 (NLS1) Mrk 335 in December 2015 caught the active galaxy at its lowest X-ray flux since 2007. The NLS1 is rel…
On the slow quenching of M* galaxies: heavily-obscured AGNs clarify the picture
Thibaud Moutard, Nicola Malavasi, Marcin Sawicki +2
We investigate the connection between X-ray and radio-loud AGNs and the physical properties of their evolved and massive host galaxies, focussing on the mass-related quenching chan…
