The flaring X-ray corona in the quasar PDS 456
James Reeves, Valentina Braito, Delphine Porquet +3
New Swift monitoring observations of the variable, radio-quiet quasar, PDS 456, are presented. A bright X-ray flare was captured in September 2018, the flux increasing by a factor…
A Full Characterisation of the Supermassive Black Hole in IRAS 09149-6206
D. J. Walton, W. N. Alston, P. Kosec +11
We present new broadband X-ray observations of the type-I Seyfert galaxy IRAS 09149-6206, taken in 2018 with -, and . The source is highly complex, sho…
Revisiting the complex nuclear region of NGC 6240 with Chandra
G. Fabbiano, A. Paggi, M. Karovska +3
We present a reanalysis of the cumulative ACIS S Chandra data set pointed at the double AGNs of the NGC 6240 merging galaxy, focusing on the hard energy bands containing the hard s…
The nearby extreme accretion and feedback system PDS 456: finding a complex radio-emitting nucleus
Jun Yang, Zsolt Paragi, Emanuele Nardini +5
When a black hole accretes close to the Eddington limit, the astrophysical jet is often accompanied by radiatively driven, wide-aperture and mildly relativistic winds. Powerful win…
The first broadband X-ray view of the narrow line Seyfert 1 Ton S180
G. A. Matzeu, E. Nardini, M. L. Parker +15
We present joint \textit{XMM-Newton} and \textit{NuSTAR} observations of the `bare' narrow line Seyfert 1 Ton S180 (), carried out in 2016 and providing the first hard X-r…
Observations of Four Nearby X-ray Faint AGN: Low Luminosity or Heavy Obscuration?
A. Annuar, D. M. Alexander, P. Gandhi +20
We present observations of four active galactic nuclei (AGN) located within 15 Mpc. These AGN, namely ESO 121-G6, NGC 660, NGC 3486 and NGC 5195, have observed X-ray lumin…
