Radio spectra of narrow-line Seyfert 1 galaxies observed with ATCA and VLASS
Sina Chen, Jamie B. Stevens, Philip G. Edwards +7
We present radio spectral analyses for a sample of 29 radio-quiet (RQ) and three radio-loud (RL) narrow-line Seyfert 1 galaxies (NLS1s) detected with the Australia Telescope Compac…
Hard - X-rays selected Active Galactic Nuclei. I. A radio view at high-frequencies
E. Chiaraluce, F. Panessa, G. Bruni +5
A thorough study of radio emission in Active Galactic Nuclei (AGN) is of fundamental importance to understand the physical mechanisms responsible for the emission and the interplay…
The ionic composition of the local absorber towards 3C 273
Itay Gissis, Uria Peretz, Ehud Behar
Hot ionized gas is observed in the local vicinity of our galaxy through spectral absorption features. The most common hypothesis is that this gas forms a halo surrounding our Milky…
Multi-wavelength campaign on NGC 7469 V. Analysis of the HST/COS observations: Super solar metallicity, distance, and trough variation models
N. Arav, X. Xu, G. A. Kriss +18
Aims. Our aim is to determine the distance of the UV outflow components from the central source, their abundances and total column density, and the mechanism responsible for their…
Multi-wavelength Campaign on NGC 7469 VI. Photoionisation Modelling of the Emission Line Regions and the Warm Absorber
S. Grafton-Waters, G. Branduardi-Raymont, M. Mehdipour +16
Aims. We aim to investigate and characterise the photoionised X-ray emission line regions within NGC 7469. Methods. We apply the photoionisation model, PION, within the spectral fi…
The physics and astrophysics of X-ray outflows from Active Galactic Nuclei
Sibasish Laha, Randall Smith, Panayiotis Tzanavaris +20
The highly energetic outflows from Active Galactic Nuclei detected in X-rays are one of the most powerful mechanisms by which the central supermassive black hole (SMBH) interacts w…
