Refining Chandra/ACIS Subpixel Event Repositioning Using a Backside Illuminated CCD Model
Jingqiang Li, Joel H. Kastner, Gregory Y. Prigozhin +1
Subpixel event repositioning (SER) techniques have been demonstrated to significantly improve the already unprecedented spatial resolution of Chandra X-ray imaging with the Advance…
The Flight Spectral Response of the ACIS Instrument
Paul P. Plucinsky, Norbert S. Schulz, Herman L. Marshall +11
We discuss the flight calibration of the spectral response of the Advanced CCD Imaging Spectrometer (ACIS) on-board the Chandra X-ray Observatory (CXO). The spectral resolution and…
Highly Resolved X-ray Spectra with Chandra: Dynamics of Neutral and Ionized Matter
Norbert S. Schulz
The High Energy Transmission Grating Spectrometer (HETGS) onboard the Chandra X-ray Observatory has so far produced a large number of high resolution X-ray spectra with unprecedent…
Using the High Resolution X-ray Spectrum of PSR B0656+14 to Constrain the Chemical Composition of the Neutron Star Atmosphere
H. L. Marshall, N. S. Schulz
Observations of PSR B0656+14 using the Chandra Low Energy Transmission Grating Spectrometer are presented. The zeroth order events are pulsed at an amplitude of 10 +/- 2% and the i…
Chandra High-Resolution Spectrum of the Anomalous X-ray Pulsar 4U 0142+61
Adrienne M. Juett, Herman L. Marshall, Deepto Chakrabarty +1
We report on a 25 ks observation of the 8.7 s anomalous X-ray pulsar 4U~0142+61 with the High Energy Transmission Grating Spectrometer (HETGS) on the Chandra X-ray Observatory. The…
