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…

Accretion in Strong Field Gravity with eXTP

Alessandra De Rosa, Phil Uttley, Lijun Gou +99

In this paper we describe the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies related to accretion flows in the strong field gravity regime around…

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…

The long outburst of the black hole transient GRS 1716-249 observed in the X-ray and radio band

T. Bassi, M. Del Santo, A. D'Aì +9

We present the spectral and timing analysis of X-ray observations performed on the Galactic black hole transient GRS 1716-249 during the 2016-2017 outburst. The source was almost c…

Faint -ray sources at low-redshift: the radio galaxy IC 1531

T. Bassi, G. Migliori, P. Grandi +6

We present a multi-wavelength study of IC 1531 (z=0.02564), an extragalactic radio source associated with the -ray object 3FGL J0009.9-3206 and classified as a blazar of uncerta…

NuSTAR reveals that the heavily obscured nucleus of NGC 2785 was the contaminant of IRAS 09104+4109 in the BeppoSAX/PDS hard X-rays

C. Vignali, P. Severgnini, E. Piconcelli +7

The search for heavily obscured active galactic nuclei (AGNs) has been revitalized in the last five years by NuSTAR, which has provided a good census and spectral characterization…

First observations of speed of light tracks by a fluorescence detector looking down on the atmosphere

G. Abdellaoui, S. Abe, J. H. Adams +311

EUSO-Balloon is a pathfinder mission for the Extreme Universe Space Observatory onboard the Japanese Experiment Module (JEM-EUSO). It was launched on the moonless night of the 25$^…

Dramatic change in the boundary layer in the symbiotic recurrent nova T Coronae Borealis

G. J. M. Luna, K. Mukai, J. L. Sokoloski +6

A sudden increase in the rate at which material reaches the most internal part of an accretion disk, i.e. the boundary layer, can change its structure dramatically. We have witness…

Broadband spectral analysis of MXB 1659-298 in its soft and hard state

R. Iaria, S. M. Mazzola, T. Bassi +7

The X-ray transient eclipsing source MXB 1659-298 went into outburst in 1999 and 2015. During these two outbursts the source was observed by XMM-Newton, nuSTAR, and Swift/XRT. Usin…

Swift data hint at a binary Super Massive Black Hole candidate at sub-parsec separation

P. Severgnini, C. Cicone, R. Della Ceca +10

Dual/binary Supermassive Black Hole (SMBH) systems are the inevitable consequence of the current Lambda Cold Dark Matter cosmological paradigm. In this context, we discuss here the…

The Geant4 mass model of the ATHENA Silicon Pore Optics and its effect on soft proton scattering

Valentina Fioretti, Andrea Bulgarelli, Simone Lotti +6

Given the unprecedented effective area, the new ATHENA Silicon Pore Optics (SPO) focusing technology, the dynamic and variable L2 environment, where no X-ray mission has flown up t…

Indication of anisotropy in arrival directions of ultra-high-energy cosmic rays through comparison to the flux pattern of extragalactic gamma-ray sources

The Pierre Auger Collaboration, A. Aab, P. Abreu +390

A new analysis of the dataset from the Pierre Auger Observatory provides evidence for anisotropy in the arrival directions of ultra-high-energy cosmic rays on an intermediate angul…

X-ray, UV, and optical observations of the accretion disk and boundary layer in the symbiotic star RT Cru

G. J. M. Luna, K. Mukai, J. L. Sokoloski +8

Compared to mass transfer in cataclysmic variables, the nature of accretion in symbiotic binaries in which red giants transfer material to white dwarfs (WDs) has been difficult to…
