Suzaku Observations of Tycho's Supernova Remnant
T. Tamagawa, A. Hayato, S. Nakamura +19
Tycho's supernova remnant was observed by the XIS and HXD instruments onboard the Suzaku satellite on 2006 June 26-29 for 92 ks. The spectrum up to 30 keV was well fitted with a tw…
X-Ray Emission from Supernova Remnants Observed in the ASCA Galactic Plane Survey
Shigeo Yamauchi, Masaru Ueno, Katsuji Koyama +1
X-ray images and spectra of 5 cataloged supernova remnants (SNRs), G12.0-0.1, G346.6-0.2, G348.5+0.1, G348.7+0.3, and G355.6-0.0, observed in the ASCA galactic plane survey are pre…
Suzaku Observation of AXP 1E 1841-045 in SNR Kes 73
M. Morii, S. Kitamoto, N. Shibazaki +7
Anomalous X-ray pulsars (AXPs) are thought to be magnetars, which are neutron stars with ultra strong magnetic field of -- G. Their energy spectra below 10…
SGR 1806-20 about two years after the giant flare: Suzaku, XMM-Newton and INTEGRAL observations
P. Esposito, S. Mereghetti, A. Tiengo +9
In December 2004, the soft gamma-ray repeater SGR 1806-20 emitted the most powerful giant flare ever observed. This probably involved a large-scale rearrangement of the magnetosphe…
PoGOLite - A High Sensitivity Balloon-Borne Soft Gamma-ray Polarimeter
Tuneyoshi Kamae, Viktor Andersson, Makoto Arimoto +36
We describe a new balloon-borne instrument (PoGOLite) capable of detecting 10% polarisation from 200mCrab point-like sources between 25 and 80keV in one 6 hour flight. Polarisation…
Measuring energy dependent polarization in soft gamma-rays using Compton scattering in PoGOLite
M. Axelsson, O. Engdegård, F. Ryde +23
Linear polarization in X- and gamma-rays is an important diagnostic of many astrophysical sources, foremost giving information about their geometry, magnetic fields, and radiation…
