Chandra and HST Observations of Radio-Selected (Wandering) Massive Black Hole Candidates in Dwarf Galaxies

Megan R. Sturm, Amy E. Reines, Anne M. Lohfink +6

We present Chandra X-ray Observatory and Hubble Space Telescope (HST) follow-up observations of 12 dwarf galaxies from Reines et al. (2020) that are potential hosts of radio-select…

Intensive disc-reverberation mapping of Fairall 9: 1st year of Swift & LCO monitoring

J. V. Hernández Santisteban, R. Edelson, K. Horne +33

We present results of time-series analysis of the first year of the Fairall 9 intensive disc-reverberation campaign. We used Swift and the Las Cumbres Observatory global telescope…

Discovery of an X-ray Quasar Wind Driving the Cold Gas Outflow in the Ultraluminous Infrared Galaxy IRAS F05189-2524

Robyn N. Smith, Francesco Tombesi, Sylvain Veilleux +2

We present new XMM-Newton and NuSTAR observations of the galaxy merger IRAS F05189-2524 which is classified as an ultra-luminous infrared galaxy (ULIRG) and optical Seyfert 2 at $z…

Radio continuum and X-ray emission from the most extreme FIR-excess galaxy NGC 1377: An extremely obscured AGN revealed

F. Costagliola, R. Herrero-Illana, A. Lohfink +4

Galaxies which strongly deviate from the radio-far IR correlation are of great importance for studies of galaxy evolution as they may be tracing early, short-lived stages of starbu…

The rhythm of Fairall 9 -- I: Observing the spectral variability with XMM-Newton and NuSTAR

Anne Lohfink, Christopher Reynolds, Ciro Pinto +13

We present a multi-epoch X-ray spectral analysis of the Seyfert 1 galaxy Fairall 9. Our analysis shows that Fairall 9 displays unique spectral variability in that its ratio residua…

The view of AGN-host alignment via reflection spectroscopy

Matthew J. Middleton, Michael L. Parker, Christopher S. Reynolds +2

The fuelling of active galactic nuclei (AGN) - via material propagated through the galactic disc or via minor mergers - is expected to leave an imprint on the alignment of the sub-…

The fast UV variability of the active galactic nucleus in Fairall 9

Anne Lohfink, Christopher Reynolds, Ranjan Vasudevan +2

We present results from a new optical/UV/X-ray monitoring campaign of the luminous Seyfert galaxy Fairall 9 using the Swift satellite. Using the UV-Optical Telescope (UVOT) on Swif…
