MAXI investigation into the longterm X-ray variability from the very-high-energy gamma-ray blazar Mrk 421
Naoki Isobe, Ryosuke Sato, Yoshihiro Ueda +10
The archetypical very-high-energy gamma-ray blazar Mrk 421 was monitored for more than 3 years with the Gas Slit Camera onboard Monitor of All Sky X-ray Image (MAXI), and its longt…
MAXI: all-sky observation from the International Space Station
Tatehiro Mihara, Mutsumi Sugizaki, Masaru Matsuoka +8
Monitor of All-sky X-ray Image (MAXI) is mounted on the International Space Station (ISS). Since 2009 it has been scanning the whole sky in every 92 minutes with ISS rotation. Due…
A new X-ray nova MAXI J1910-057 (= Swift J1910.2-0546) and mass-accretion inflow
Satoshi Nakahira, Hitoshi Negoro, Megumi Shidatsu +5
We report on a long-term monitoring of a newly discovered X-ray nova, MAXI J1910-057 (= Swift J1910.2-0546), by MAXI and Swift. The new X-ray transient was first detected on 2012 M…
High-z gamma-ray bursts for unraveling the dark ages mission HiZ-GUNDAM
Daisuke Yonetoku, Tatehiro Mihara, Tatsuya Sawano +28
We are now investigating and studying a small satellite mission HiZ-GUNDAM for future observation of gamma-ray bursts (GRBs). The mission concept is to probe "the end of dark ages…
MAXI observations of GRBs
Motoko Serino, Takanori Sakamoto, Nobuyuki Kawai +40
Monitor of all-sky image (MAXI) Gas Slit Camera (GSC) detects gamma-ray bursts (GRBs) including the bursts with soft spectra, such as X-ray flashes (XRFs). MAXI/GSC is sensitive to…
Sudden End of X-Ray Outbursts around Periastron of Circinus X-1 Observed with MAXI
Kazumi Asai, Tatehiro Mihara, Masaru Matsuoka +5
MAXI/GSC observed 21 outbursts from Circinus X-1 between 2009 August and 2013 December. Although 14 outbursts showed ordinary gradual decays, in 7 outbursts we found sudden luminos…
