Characterizing the -ray Emission from FR0 Radio Galaxies
Nikita S. Khatiya, Margot Boughelilba, Christopher M. Karwin +5
FR0 galaxies constitute the most abundant jet population in the local Universe. With their compact jet structure, they are broadband photon emitters and have been proposed as multi…
Compton-thick AGN in the NuSTAR Era X: Analysing seven local CT-AGN candidates
Dhrubojyoti Sengupta, Stefano Marchesi, Cristian Vignali +14
We present the broad-band X-ray spectral analysis (0.6-50 keV) of seven Compton-Thick active galactic nuclei (CT-AGN; line-of-sight, l.o.s., column density cm) ca…
Probing the Origin of Changing-look Quasar Transitions with Chandra
Qian Yang, Paul J. Green, Chelsea L. MacLeod +9
Extremely variable quasars can also show strong changes in broad-line emission strength and are known as changing-look quasars (CLQs). To study the CLQ transition mechanism, we pre…
A New Mid-Infrared and X-ray Machine Learning Algorithm to Discover Compton-thick AGN
Ross Silver, Núria Torres-Alba, Xiurui Zhao +4
We present a new method to predict the line-of-sight column density (NH) values of active galactic nuclei (AGN) based on mid-infrared (MIR), soft, and hard X-ray data. We developed…
A Simple Method for Predicting Variability in Active Galactic Nuclei
Isaiah Cox, Nuria Torres-Alba, Stefano Marchesi +4
The unified model of active galactic nuclei (AGN) includes a toroidal obscuring structure to explain the differences between Type I and Type II AGN as an effect of inclination angl…
