INTEGRAL reloaded: spacecraft, instruments and ground system
Erik Kuulkers, Carlo Ferrigno, Peter Kretschmar +85
ESA's INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) was launched on 17 Oct 2002 at 06:41 CEST. Since then, it has been providing long, uninterrupted observations (up t…
Gamma-ray Astrophysics in the MeV Range: the ASTROGAM Concept and Beyond
Alessandro De Angelis, Vincent Tatischeff, Andrea Argan +26
The energy range between about 100 keV and 1 GeV is of interest for a vast class of astrophysical topics. In particular, (1) it is the missing ingredient for understanding extreme…
Origin of the in-orbit instrumental background of the Hard X-ray Imager onboard Hitomi
Kouichi Hagino, Hirokazu Odaka, Goro Sato +43
Understanding and reducing the in-orbit instrumental backgrounds are essential to achieving high sensitivity in hard X-ray astronomical observations. The observational data of the…
Concept study of a small Compton polarimeter to fly on a CubeSat
Yi-Chi Chang, Chien-Ying Yang, Hung-Hsiang Liang +5
Application of cubesats in astronomical observations has been getting more and more mature in recent years. Here we report a concept study of a small Compton polarimeter to fly on…
Feasibility of Observing Gamma-ray Polarization from Cygnus X-1 Using a CubeSat
Chien-Ying Yang, Yi-Chi Chang, Hung-Hsiang Liang +7
Instruments flown on CubeSats are small. Meaningful applications of CubeSats in astronomical observations rely on the choice of a particular subject that is feasible for CubeSats.…
In-orbit performance and calibration of the Hard X-ray Imager onboard Hitomi (ASTRO-H)
Kouichi Hagino, Kazuhiro Nakazawa, Goro Sato +37
The Hard X-ray Imager (HXI) onboard Hitomi (ASTRO-H) is an imaging spectrometer covering hard X-ray energies of 5-80 keV. Combined with the hard X-ray telescope, it enables imaging…
Modeling of proton-induced radioactivation background in hard X-ray telescopes: Geant4-based simulation and its demonstration by Hitomi's measurement in a low Earth orbit
Hirokazu Odaka, Makoto Asai, Kouichi Hagino +47
Hard X-ray astronomical observatories in orbit suffer from a significant amount of background due to radioactivation induced by cosmic-ray protons and/or geomagnetically trapped pr…
Hard X-ray polarimetry with Caliste, a high performance CdTe based imaging spectrometer
S. Antier, P. Ferrando, O. Limousin +11
Since the initial exploration of soft gamma-ray sky in the 60's, high-energy celestial sources have been mainly characterized through imaging, spectroscopy and timing analysis. Des…
The ASTRO-H X-ray Astronomy Satellite
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +250
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions developed by the Institute of Space and Astronautical Science (ISAS), with a planne…
The COSPIX mission: focusing on the energetic and obscured Universe
P. Ferrando, A. Goldwurm, P. Laurent +57
Tracing the formation and evolution of all supermassive black holes, including the obscured ones, understanding how black holes influence their surroundings and how matter behaves…
The ASTRO-H Mission
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +174
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will…
