Centaurus A: Exploring the Nature of the Hard X-ray/Soft Gamma-ray Emission with INTEGRAL
James Rodi, E. Jourdain, M. Molina +1
The question of the origin of the hard X-ray/soft gamma-ray emission in Centaurus A (Cen A) persists despite decades of observations. Results from X-ray instruments suggest a jet o…
MAXI J1535-571 2017 outburst Seen by INTEGRAL/SPI and Investigating the Origin of Its Hard Tail
James Rodi, E. Jourdain, J. P. Roques
On 2 September 2017 MAXI J1535-571 went into outburst and peaked at ~5 Crab in the 2-20 keV energy range. Early in the flare INTEGRAL performed Target of Opportunity pointings and…
Limits on X-ray Polarization at the Core of Centaurus A as Observed with the Imaging X-ray Polarimetry Explorer
Steven R. Ehlert, Riccardo Ferrazzoli, Andrea Marinucci +95
We present measurements of the polarization of X-rays in the band from the nucleus of the radio galaxy Centaurus A (Cen A), using a 100ks observation…
INTEGRAL Results on Gamma-Ray Bursts and Polarization of Hard X-ray Sources
D Gotz, C. Gouiffes, J. Rodriguez +9
In this paper we first review the results obtained by the INTEGRAL mission in the domain of Gamma-Ray Bursts (GRBs), thanks to the INTEGRAL Burst Alert System, which is able to del…
Hybrid Comptonization and Electron-Positron Pair Production in the Black-Hole X-Ray Binary MAXI J1820+070
Andrzej A. Zdziarski, Elisabeth Jourdain, Piotr Lubinski +6
We study X-ray and soft gamma-ray spectra from the hard state of the accreting black-hole binary MAXI J1820+070. We perform analysis of two joint spectra from NuSTAR and INTEGRAL,…
Multi-messenger astronomy with INTEGRAL
C. Ferrigno, V. Savchenko, A. Coleiro +19
At the time of defining the science objectives of the INTernational Gamma-Ray Astrophysics Laboratory (INTEGRAL), such a rapid and spectacular development of multi-messenger astron…
