Transient obscuration event captured in NGC 3227 IV. Origin of the obscuring cloud variability

S. Grafton-Waters, J. Mao, M. Mehdipour +13

Obscuration events in type I active galactic nuclei (AGN) have been detected more frequently in recent years. The strong flux decrease in the soft X-ray band between observations h…

Compton-thick AGN in the NuSTAR Era. IX. A Joint NuSTAR and XMM-Newton Analysis of Four Local AGN

Ross Silver, Nuria Torres-Alba, Xiurui Zhao +7

We present the results of the broadband X-ray spectral analysis of simultaneous NuSTAR and XMM-Newton observations of four nearby Compton-thick active galactic nuclei (AGN) candida…

Compton-thick AGNs in the NuSTAR era. V: Joint NuSTAR and XMM-Newton spectral analysis of three "soft-Gamma" candidate CT-AGNs in the Swift-BAT 100-month catalog

Stefano Marchesi, Marco Ajello, Xiurui Zhao +3

We present the joint NuSTAR and XMM-Newton spectral analysis in the 0.6-70 keV band of three candidate Compton thick (CT-) AGN selected in the 100-month Swift-BAT catalog. These ob…

Compton-thick AGN in the NuSTAR era III: A systematic study of the torus covering factor

Stefano Marchesi, Marco Ajello, Xiurui Zhao +9

We present the analysis of a sample of 35 candidate Compton thick (CT-) active galactic nuclei (AGNs) selected in the nearby Universe (average redshift <z>~0.03) with the Swift-BAT…

Compton-thick AGN in the NuSTAR era II: A deep NuSTAR and XMM-Newton view of the candidate Compton thick AGN in NGC 1358

X. Zhao, S. Marchesi, M. Ajello +4

We present the combined NuSTATR and XMM-Newton 0.6-79 keV spectral analysis of a Seyfert 2 galaxy, NGC 1358, which we selected as a candidate Compton thick (CT-) active galactic nu…

Chandra and NuSTAR follow-up observations of Swift-BAT selected AGN

Stefano Marchesi, Luke Tremblay, Marco Ajello +5

Based on current models of the Cosmic X-ray Background (CXB), heavily obscured Active Galactic Nuclei (AGN) are expected to make up ~10% of the peak emission of the CXB and ~20% of…

The merger fraction of active and inactive galaxies in the local Universe through an improved non-parametric classification

Stefano Cotini, Emanuele Ripamonti, Alessandro Caccianiga +5

We investigate the possible link between mergers and the enhanced activity of supermassive black holes (SMBHs) at the centre of galaxies, by comparing the merger fraction of a loca…

The broad-band X-ray spectrum of the Seyfert 1 galaxy, MCG+8-11-11

Stefano Bianchi, Ilaria De Angelis, Giorgio Matt +5

We present a long (100 ks) Suzaku observation of one of the X-ray brightest AGN, MCG+8-11-11. These data were complemented with the 54-month Swift BAT spectrum, allowing us to perf…

On the metal abundances inside mixed-morphology supernova remnants: the case of IC443 and G166.0+4.3

F. Bocchino, M. Miceli, E. Troja

Recent developments on the study of mixed morphology supernova remnants (MMSNRs) have revealed the presence of metal rich X-ray emitting plasma inside a fraction of these remnant,…
