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…
Suzaku Observation of the Black Hole Binary 4U 1630--47 in the Very High State
Takafumi Hori, Yoshihiro Ueda, Megumi Shidatsu +7
We report the results from an X-ray and near-infrared observation of the Galactic black hole binary 4U 1630--47 in the very high state, performed with {\it Suzaku} and IRSF around…
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…
GRB 130925A: an ultra-long Gamma Ray Burst with a dust-echo afterglow, and implications for the origin of the ultra-long GRBs
P. A. Evans, R. Willingale, J. P. Osborne +24
GRB 130925A was an unusual GRB, consisting of 3 distinct episodes of high-energy emission spanning 20 ks, making it a member of the proposed category of `ultra-long' bursts.…
