GW observatories will be ready in the late 2010’s.
• Finer localiza:on (~0.1deg) • Iden:fy electromagne:c counterpart
However, poor localiza:on (> a few deg)
iWF-‐MAXI
GW candidate = short GRB
• One of the most probable GW source
• with a so# extended emission SoT X-‐ray band is important !!
at a few keV
NS-‐NS merger
iWF-‐MAXI
16CCDs
Energy range: 0.7 keV〜10keV FoV: 〜25% of the enLre sky Localiza:on: 0.1 deg ISS/JEM payload Opera:on: 2018 (TBD)〜
CCD arrays with coded masks
ISS
“i” stands for iSEEP ü Medium-‐size bus for
JEM Cooler
Good NEWS !! • We submibed our proposal of iWF-‐MAXI to “Small-‐size Project 2015” by ISAS in Feb. 2015
• iWF-‐MAXI has been RECOMMENDED for implementaLon as an ISAS project by the Steering Commibee for Space Science of Japan in June 2015 !!
• Wai:ng for ISAS decision for star:ng the iWF-‐MAXI project
