The 7-year MAXI/GSC X-ray Source Catalog in the High Galactic-Latitude Sky (3MAXI)

Taiki Kawamuro, Yoshihiro Ueda, Megumi Shidatsu +28

We present the third MAXI/GSC catalog in the high Galactic-latitude sky () based on the 7-year data from 2009 August 13 to 2016 July 31, complementary to that in th…

Probing the stellar wind environment of Vela X-1 with MAXI

C. Malacaria, T. Mihara, A. Santangelo +4

Vela X-1 is among the best studied and most luminous accreting X-ray pulsars. The supergiant optical companion produces a strong radiatively-driven stellar wind, which is accreted…

Spectral Lag Relations in GRB Pulses Detected with HETE-2

M. Arimoto, N. Kawai, K. Asano +36

Using a pulse-fit method, we investigate the spectral lags between the traditional gamma-ray band (50-400 keV) and the X-ray band (6-25 keV) for 8 GRBs with known redshifts (GRB 01…

Discovery of a New X-Ray Burst/Millisecond Accreting Pulsar HETE J1900.1-2455

M. Suzuki, N. Kawai, T. Tamagawa +16

A class of low-mass X-ray binary sources are known to be both X-ray burst sources and millisecond pulsars at the same time. A new source of this class was discovered by High Energy…

HETE-2 Localization and Observations of the Gamma-Ray Burst GRB 020813

R. Sato, the HETE Science Team

A bright, long gamma-ray burst (GRB) was detected and localized by the instruments on board the High Energy Transient Explorer 2 satellite (HETE-2) at 02:44:19.17 UTC (9859.17 s UT…

XMM observations of the high-redshift quasar RXJ1028.6-0844 at z=4.276: soft X-ray spectral flattening

W. Yuan, A. C. Fabian, A. Celotti +2

We present results from a new XMM-Newton observation of the high-redshift quasar RXJ1028.6-0844 at a redshift of 4.276. The soft X-ray spectral flattening, as reported by a study w…
