High Energy Observations of XRF 030723: Evidence for an Off-axis Gamma-Ray Burst?
N. R. Butler, T. Sakamoto, M. Suzuki +34
We report High Energy Transient Explorer 2 (HETE-2) Wide Field X-ray Monitor/French Gamma Telescope observations of XRF030723 along with observations of the XRF afterglow made usin…
Previously Claimed(/Unclaimed) X-ray Emission Lines in High Resolution Afterglow Spectra
N. Butler, A. Dullighan, P. Ford +5
We review the significance determination for emission lines in the Chandra HETGS spectrum for GRB020813, and we report on a search for additional lines in high resolution Chandra s…
Optical and X-ray Observations of the Afterglow to XRF030723
N. Butler, A. Dullighan, P. Ford +6
The X-ray-flash XRF030723 was detected by the HETE satellite and rapidly disseminated, allowing for an optical transient to be detected ~1 day after the burst. We discuss observati…
Chandra Observations of the Optically Dark GRB030528
N. Butler, A. Dullighan, P. Ford +5
The X-ray-rich GRB030528 was detected by the HETE satellite and its localization was rapidly disseminated. However, early optical observations failed to detect a counterpart source…
