We are conducting a systematic study of highly-ionised outflows in AGN using archival Suzaku data. To date we have analysed 59 observations of 45 AGN using a combined energy-intensity contour plot and Montecarlo method. We find that ~36% (16/45) of sources analysed so far show largely unambigous signatures (i.e., Montecarlo proabilities of >95%) of highly-ionised, high-velocity absorption troughs in their X-ray spectra. From XSTAR fitting we find that, overall, the properties of the absorbers…

Constraining the geometry of the nuclear wind in PDS 456 using a novel emission model
Context. Outflows from active galactic nuclei (AGN) are often invoked to explain the co-evolution of AGN and their host galaxies, and the scaling relations between the central black hole mass and the…
Numerical Study on Outflows in Seyfert Galaxies I: Narrow Line Region Outflows in NGC 4151
The origin of narrow line region (NLR) outflows remains unknown. In this paper, we explore the scenario in which these outflows are circumnuclear clouds driven by energetic accretion disk winds. We…
Probing the gaseous halo of galaxies through non-thermal emission from AGN-driven outflows
Feedback from outflows driven by active galactic nuclei (AGN) can affect the distribution and properties of the gaseous halos of galaxies. We study the hydrodynamics and non-thermal emission from the…
Optical Variability Modelling Of Newly Identified Blazars And Blazar Candidates Behind Magellanic Clouds
We present results of a variability study in the optical band of 44 newly identified blazar candidates behind the Magellanic Clouds. Our sample contains 27 flat spectrum radio quasars (FSRQs) and 17…
Wind from the black-hole accretion disk driving a molecular outflow in an active galaxy
TLDR
Observations of a powerful accretion-disk wind with a mildly relativistic velocity in the X-ray spectrum of IRAS F11119+3257, a nearby optically classified type 1 ultraluminous infrared galaxy hosting a powerful molecular outflow are reported.

X-ray ionized reflection occurs when a surface is irradiated with X-rays so intense that its ionization state is determined by the ionization parameter xi propto F/n, where F is the incident flux and…
A Fundamental Relation between Compact Stellar Nuclei, Supermassive Black Holes, and Their Host Galaxies
Imaging surveys with the Hubble Space Telescope (HST) have shown that ?50%-80% of low- and intermediate-luminosity galaxies contain a compact stellar nucleus at their center, regardless of host…
Statistics, Handle with Care: Detecting Multiple Model Components with the Likelihood Ratio Test
TLDR
This paper characterize an important class of problems in which the LRT and the F-test fail and illustrate this nonstandard behavior, and briefly sketch several possible acceptable alternatives, focusing on Bayesian posterior predictive probability values.
