All-sky Medium Energy Gamma-ray Observatory: Exploring the Extreme Multimessenger Universe
Julie McEnery, Juan Abel Barrio, Ivan Agudo +182
The All-sky Medium Energy Gamma-ray Observatory (AMEGO) is a probe class mission concept that will provide essential contributions to multimessenger astrophysics in the late 2020s…
The nature of the multi-wavelength emission of 3C 111
S. de Jong, V. Beckmann, F. Mattana
We attempt to determine the nature of the high energy emission of the radio galaxy 3C 111, by distinguishing between the effects of the thermal and non-thermal processes. We study…
High-energy emission from NGC 5506, the brightest hard X-ray Narrow Line Seyfert 1 galaxy
S. Soldi, V. Beckmann, N. Gehrels +2
We present results on the hard X-ray emission of NGC 5506, the brightest narrow line Seyfert 1 galaxy above 20 keV. All the recent observations by INTEGRAL, Swift and Suzaku have b…
The Hard X-ray Emission of Cen A
V. Beckmann, P. Jean, P. Lubinski +2
The radio galaxy Cen A has been detected all the way up to the TeV energy range. This raises the question about the dominant emission mechanisms in the high-energy domain. Spectral…
The hard synchrotron X-ray spectrum of the TeV BL Lac 1ES 1426+428
A. Wolter, V. Beckmann, G. Ghisellini +5
We have observed 1ES 1426+428 with INTEGRAL detecting it up to 150 keV. The spectrum is hard, confirming that this source is an extreme BL Lac object, with a synchrotron comp…
The nature of the hard state of Cygnus X-3
L. Hjalmarsdotter, A. A. Zdziarski, S. Larsson +4
The X-ray binary Cygnus X-3 is a highly variable X-ray source that displays a wide range of observed spectral states. One of the main states is significantly harder than the others…
