3.0 Instrument Status and Science Support
3.1 Flight Events and HETG Instrument Status
The HETG continues to function with no outstanding issues.
There were 2 HETG GO observations in July and 4 HETG observations (2 TOO, 2 GO) in August.
3.2 Science Support to CXC, SWG, etc.
Continued checking HRMA FWHM during HETG observations by looking at one of the August GO observations (obsid 4584) – the streak width remains stable.
Progress has been made in finalizing the small calibration adjustments to the geometry of the ACIS-S, specifically a test geometry file with adjusted chip rotation values has been created and is being used in the next step of determining any chip gap corrections needed. These are planned to be completed by the Calibration Workshop in October.
Progress made in updating and organizing the HETG web pages at http://space.mit.edu/HETG ; effort will continue in next months with completion by the end of the calendar year.

Optical Confirmation of E0102 Velocities
In our past work
described in Flanagan et al. 2004, we were able to analyze the HETG observation
of SNR E0102 to obtain the color-coded-velocity image shown at left. This image gives the velocity of the Ne-X ion
emission: red represents motion away from us in the range 500 to 2200 km/s, and
green and blue are velocities towards us of order 900 km/s and 1800 km/s,
respectively.
In January of 2004 optical (~5000 Å) long-slit spectra were taken for us by astrophysicist You-Hua Chu; these data are plotted at right. The slit ran from lower left to upper right on the color image and corresponds to bottom-to-top on the data at right. The vertical dashed line at about “110” on the x-axis corresponds to rest-frame O III emission; velocities away from us are to the right and velocities towards us are to the left of that dashed line.
Some clear similarities between the X-ray Ne-X and optical O III data are seen. For example, the “blue” region in the X-ray corresponds to the signal bumps seen in the data at Offsets of 4 to 6; the “green” to Offsets of –10 to –7. On the other hand, the optical data shows no or very reduced emission to the right of the dashed line, which should correspond to the “red” emission seen in the X-ray image. This may be an indication of a “dust” plane; see pages 3 and 4 in Dewey’s poster at the HEAD ’04 meeting.
E0102 Second Observation: Azimuthal Variations
Our second
observation of E0102 with the HETG was taken at a different roll angle –
with the dispersion direction running roughly North-South. The images at
left show the zeroth-order image and the
dispersed O VII F,I,R line complex. The indicated rectangular and square
regions are in the SE and SW of the remnant.
There is a clear
variation in the intensity of the emission around the ring and in the dispersed
image at far right is appears that the intensity variation is more extreme for
the forbidden line (left-most ring image) as opposed to the resonance line.
Analysis carried out by Kathy Flanagan on these two regions gives quantitative
measure of this effect. The two plots below show allowed values of T and tau for the SW and SE regions. The red
curves are derived from the forbidden-to-resonance ratio and the are clearly
different for the two regions. This work was presented at the COSPAR meeting
in July.
E0102 in 3D: De-projection of Line Images
The dispersed images of E0102 contain much information on both large scales, the amount of emission in each line, and on small scales of the detailed images of the lines. In particular the cross-dispersion profile of lines is very sensitive to the distribution of the emission in space.
Assuming the line emission comes from a 3D object of revolution shown at left with a radial variation in intensity, the parameters of the model could be fit to the line data. The result is an intensity distribution which is a function of the actual radius rather than the project-on-the-sky radius.
Using the values of fits to various lines Kathy Flanagan constructed the plot at right which shows how the model values of T and tau vary with 3D radius (the values next to each data point.) These values indicate that the plasma is hotter and “older” the further out it is in radius. This qualitatively agrees with the idea of the reverse shock moving in toward smaller radii: the inner regions are then “younger” (small tau) and have cooler electron temperatures. (This work was also presented at the COSPAR meeting.)
E0102 in 3D: A Coarse Model
Modeling of the E0102 data on a gross or coarse scale was begun using a model consisting of the sum of cylinders of emission from the various ions seen in the data (O VII, O VIII, Ne IX, Ne X, Mg XI, Mg XII, Si XIII) and an outer blastwave component of a spherical shape, e.g., see the images at right.
Adjusting the
intensity of the cylinders for rough agreement with the data gave a reasonable
overall fit to the data. The size of each ions’ cylinder was set based
on the measured radii given in Flanagan et al. 2004.
Similarly to the previous 3D fitting, the result gives a de-projected model of the emission as a function of radial coordinate in 3D. These emission values were analyzed to obtain the density of the various ions vs radius as well as the self-consistent local electron density. These density values are plotted at right.
For more details see pages 5 to 15 in Dewey’s poster at the HEAD ’04 meeting.
N103B and Type Ia Models 
We have observed the SNR N103B with the HETG and the dispersed spectra show lines of O, Ne, and Fe. To better put the measured spectrum in context, we’ve been working to calculate model spectra for Type Ia SNR based on model files from Carles Badenes, see Badenes … 2003. The images above show a “true color” Chandra image of N103B (left) and color representations of four of Badenes models (right.) An example of the spectrum calculated from the models is also shown above. The spectrum is shown at both high resolution and smoothed to CCD quality resolution. This and related work will be the focus of an upcoming poster at the XDAP meeting in November 2004 by Dewey and Houck.
4.3 HETG-related Software: Development, Evaluation, and Support
The E0102 research described above was carried out using a variery of custom software including: T-tau line ratio contour plotting s/w; 3D ray generation module for input to MARX; “v3d_” routines for 3D visualization and simulation; and custom IDL and ISIS software to calculate spectra from Badenes models (for details see “ISIS Spectra from Badenes’ Models” on the web.)
