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 6, 4, 6, and 3 HETG observation intervals, respetively, in March, April, May, and June of 2004. A total of 12 targets were observed including our Cycle 5 GTO target, MCG- -6-30-15 (4 obsids totaling 530 ks!), and a calibration observation of 3C 273 on 6/30/04.

 

 

3.2 Science Support to CXC, SWG, etc.

 

         Four of the recent HETG observations were analyzed for the FWHM of the zeroth-order image to add to our monitoring of the HRMA FWHM, see the plot on the next page. The FWHM remains stable with perhaps a hint of a slight increase in the past years. It may be reasonable to refocus the telescope later this year after the up-coming ACIS warm-up to ensure we’re at best focus.

         HETG supported the Chandra Peer Review in June.

         Improved HETG web pages have been worked on and will be rolled out soon.

 

 

 


Putting Final Touches on the HETG-ACIS Calibration

         Using archived observations taken with the HETG-ACIS and LETG-ACIS we are in the process of making final refinements on the HETG-ACIS parameters, for example calibration adjustments of slight chip rotations and the gaps between the ACIS chips.

 

 

The plot at left shows a preliminary measure of slight chip-to-chip rolls of the ACIS-S CCDs. The LETG spectrum is dispersed over all 6 chips in the left-to-right direction, TG_R. The cross-dispersion location, TG_D, is sensitively measured to a fraction of an ACIS pixel. Linear fits within each of the 6 CCDs measure the amount of roll of each chip; chips are S0 to S5, left to right.

 

After adjusting for these rolls and translations in TG_D, we’ll then refine the chip gap values (TG_R offsets) and the grating periods, et voila!

4.0 GTO Science Program

 

4.1 Observations and Data status

On July 2 the CXC announced the results of the Peer Review and the HETG GTO program for Cycle 6 is finalized; see the list of Cycle 6 observations and progress in on-going GTO analyses in Appendix A.

 

4.2 Science theme progress

The HETG GTO science efforts span a range of “science themes” given in the list below. In this report we take a sneak peek at the recent 530 ks of MCG- -6-30-15 raw data, on the next page.

MCG- -6-30-15 seen in more light

 

The Figure at top left is from “The Chandra High Energy Transmission Grating Spectrometer probes the dusty warm absorber in the Seyfert 1 galaxy MCG- -6-30-15” by Lee et al.[*], see also ApJ L554 13. This figure shows a small region of the complete spectrum along with a suggested absorption model (in red.) About 120 ks of HETG data were used to measure this spectrum.

 

[*] In “X-ray Emission from Accretion onto Black Holes”, Proceedings of a joint workshop held by the Center for Astrophysics (JHU) and the LHEA (NASA/ Goddard Space Flight Center) in Baltimore, MD, June 20-23, 2001, Eds.: T. Yaqoob and J. H. Krolik, to be published electronically.

 

 

The Figure at bottom left shows the same spectral region taken from the recently completed 530 ks HETG observation of MCG- -6-30-15. These data are very preliminary and not optimally binned or presented. Yet the increase in signal-to-noise over the previous observation is quite evident, for example, the absorption dip labeled “1-6” just above 0.72 keV is seen with clarity in the new data set.

Stay tuned for MCG results in future!

4.3 HETG-related Software: Development, Evaluation, and Support

Besides developing specialized in-house software mentioned here in past reports, the HETG scientists of course also use CXC developed software. Here’s a list of software components that are produced by or used with the CXC software – understanding these and optimizing their application to HETG analysis is part of the HETG/GTO effort.
