Mapping Gas Accretion and Stellar Kinematics to Sub-kiloparsec Scales in NGC 4696 with JWST/NIRSpec
Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35
We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
Narrow-Line Seyfert 1 Galaxies Beyond the Local X-ray Universe: An X-ray spectral sample
Jiachen Jiang, Dominic J. Walton, Luigi C. Gallo +8
Narrow-line Seyfert 1 AGNs (NLS1s) represent a unique stage in the black hole growth history, characterised by low black hole masses of approximately - solar masses…
Extreme Relativistic Reflection in the Active Galaxy ESO 033-G002
D. J. Walton, M. Balokovic, A. C. Fabian +13
We present the first high signal-to-noise broadband X-ray spectrum of the radio-quiet type-2 Seyfert ESO 033-G002, combining data from - and . The nuclear X-ra…
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…
Detection of a variable ultra-fast outflow in the Narrow Line Seyfert 1 galaxy PG 1448+273
P. Kosec, A. Zoghbi, D. J. Walton +4
Relativistically blueshifted absorption features of highly ionised ions, the so-called ultra-fast outflows (UFOs), have been detected in the X-ray spectra of a number of accreting…
An ionised accretion disc wind in Hercules X-1
P. Kosec, A. C. Fabian, C. Pinto +3
Hercules X-1 is one of the best studied highly magnetised neutron star X-ray binaries with a wealth of archival data. We present the discovery of an ionised wind in its X-ray spect…
