3 Dec 2014 | | Abstract: | The broad energy range spanned by ASTRO-H instruments, from ~0.3 to 600 keV,
with its high spectral resolution calorimeter and sensitive hard X-ray imaging,
offers unique opportunities to study black holes and their environments. The
ability to measure polarization is particularly novel, with potential sources
including blazars, Galactic pulsars and X-ray binaries. In this White Paper, we
present an overview of the synergistic instrumental capabilities and the
improvements over prior missions. We also show how ASTRO-H fits into the
multi-wavelength landscape. We present in more detail examples and simulations
of key science ASTRO-H can achieve in a typical 100 ksec observation when data
from all four instruments are combined. Specifically, we consider observations
of black-hole source (Cyg X-1 and GRS 1915+105), blazars (Mrk 421 and Mrk 501),
a quasar (3C 273), radio galaxies (Centaurus A and 3C 120), and active galaxies
with a strong starburst (Circinus and NGC 4945). We will also address possible
new discoveries expected from ASTRO-H. | | Source: | arXiv, 1412.1190 | | Services: | Forum | Review | PDF | Favorites | |
