Fifteen years of the Advanced CCD Imaging Spectrometer
Catherine E. Grant, Mark W. Bautz, Peter G. Ford +1
As the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory enters its fifteenth year of operation on orbit, it continues to perform well and produce spectacul…
Discovery of Oxygen Kalpha X-ray Emission from the Rings of Saturn
Anil Bhardwaj, Ronald F. Elsner, J. Hunter Waite +3
Using the Advanced CCD Imaging Spectrometer (ACIS), the Chandra X-ray Observatory (CXO) observed the Saturnian system for one rotation of the planet (~37 ks) on 20 January, 2004, a…
Chandra Observation of an X-ray Flare at Saturn: Evidence for Direct Solar Control on Saturn's Disk X-ray Emissions
Anil Bhardwaj, Ronald F. Elsner, J. Hunter Waite +3
Saturn was observed by Chandra ACIS-S on 20 and 26-27 January 2004 for one full Saturn rotation (10.7 hr) at each epoch. We report here the first observation of an X-ray flare from…
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…
