A new analysis of the short-duration, hard-spectrum GRB 051103, a possible extragalactic SGR giant flare (2009)

Hurley, K., Rowlinson, A., Bellm, E., Perley, D., Mitrofanov, I. G., Golovin, D. V., ...

GRB 051103 is considered to be a candidate soft gamma repeater (SGR) extragalactic giant magnetar flare by virtue of its proximity on the sky to M81/M82, as well as its time history, localization,...

Suzaku Observation of the New Soft Gamma Repeater SGR 0501+4516 in Outburst (2009)

Enoto, T., Nakagawa, Y. E., Rea, N., Esposito, P., Gotz, D., Hurley, K., ...

We present the first Suzaku observation of the new Soft Gamma Repeater SGR 0501+4516, performed on 2008 August 26, four days after the onset of bursting activity of this new member of the magnetar...

Intrinsic properties of a complete sample of HETE-2 gamma-ray bursts. A measure of the GRB rate in the Local Universe (2008)

Pélangeon, A., Nakagawa, Y. E., Hurley, K., Yoshida, A., Vanderspek, R., ...

Aims: Taking advantage of the forthcoming Catalog of the HETE-2 mission, the aim of this paper is to evaluate the main properties of HETE-2 GRBs - the E_peak, the T_90 and the E_iso - in their source...

The Swift Discovery of X-ray Afterglows Accompanying Short Bursts from SGR 1900+14 (2008)

Nakagawa, Y. E., Sakamoto, T., Sato, G., Gehrels, N., Hurley, K., Palmer, D. M.

The discovery of X-ray afterglows accompanying two short bursts from SGR 1900+14 is presented. The afterglow luminosities at the end of each observation are lower by 30-50% than their initial...

Status of GRB Observations with the Suzaku Wideband All-sky Monitor (2008)

Tashiro, M. S., Terada, Y., Urata, Y., Onda, K., Kodaka, N., Endo, A., ...

The Wide-band All-sky Monitor (WAM) is a function of the large lateral BGO shield of the Hard X-ray Detector (HXD) onboard Suzaku. Its large geometrical area of 800 cm^2 per side, the large stopping...

Swift captures the spectrally evolving prompt emission of GRB 070616 (2007)

Starling, R. L. C., O'Brien, P. T., Willingale, R., Page, K. L., Osborne, J. P., De Pasquale, M., ...

The origins of Gamma-ray Burst prompt emission are currently not well understood and in this context long, well-observed events are particularly important to study. We present the case of GRB 070616,...

Discovery of a New X-Ray Burst/Millisecond Accreting Pulsar HETE J1900.1-2455 (2006)

Suzuki, M., Kawai, N., Tamagawa, T., Yoshida, A., Nakagawa, Y. E., Tanaka, K., ...

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 Transient Explorer...

Swift and Suzaku Observations of the X-Ray Afterglow from the GRB 060105 (2006)

Tashiro, M. S., Abe, K., Angelini, L., Barthelmy, S., Gehrels, N., Ishikawa, N., ...

Results are presented of early X-ray afterglow observations of GRB 060105 by Swift and Suzaku. The bright, long gamma-ray burst GRB 060105 triggered the Swift Burst Alert Telescope (BAT) at 06:49:28...

GRB 060121: Implications of a Short/Intermediate Duration Gamma-Ray Burst at High Redshift (2006)

Postigo, A. De Ugarte, Castro-Tirado, A. J., Guziy, S., Gorosabel, J., Johannesson, G., Aloy, M. A., ...

Since the discovery of the first short-hard gamma-ray burst afterglows in 2005, the handful of observed events have been found to be embedded in nearby (z < 1), bright underlying galaxies. We present...
