Was the soft X-ray flare in NGC 3599 due to an AGN disc instability or a delayed tidal disruption event?
Richard D. Saxton, Sara E. Motta, S. Komossa +1
We present unpublished data from a tidal disruption candidate in NGC 3599 which show that the galaxy was already X-ray bright 18 months before the measurement which led to its clas…
IC 3599 did it again: A second outburst of the X-ray transient Seyfert 1.9 Galaxy
Dirk Grupe, S. Komossa, Richard Saxton
We report on the Swift discovery of a second high-amplitude (factor 100) outburst of the Seyfert 1.9 galaxy IC 3599, and discuss implications for outburst scenarios. Swift detected…
The XMM-Newton serendipitous survey. VII. The third XMM-Newton serendipitous source catalogue
S. R. Rosen, N. A. Webb, M. G. Watson +37
Thanks to the large collecting area (3 x ~1500 cm at 1.5 keV) and wide field of view (30' across in full field mode) of the X-ray cameras on board the European Space Agency X-r…
Seyfert galaxies with Swift: giant flares, rapid drops, and other surprises
S. Komossa, D. Grupe, R. Saxton +1
Swift has initiated a new era of understanding the extremes of active galactic nuclei (AGN) variability, their drivers and underlying physics. This is based on its rapid response,…
