HETG GTO Science Program
In the post-launch phase of the mission, the HETG group is carrying out science investigations, using alloted Guaranteed Time Observations to study a variety of astrophysical sources. The observations in this program are listed here by category and observation cycle:

These observations can be found by searching the Chandra Data Archive by setting the PI_Name field to: Canizares.
Extended sources observed with the HETG

One of the goals of our GTO activies is to make the most of the HETG. Observations of extended sources are more difficult to analyze and interpret than point sources (see Dewey 2002) - but they can have unique science rewards. Of the ~ 25 extended sources observed with the HETG, 16 of them are from our GTO program:
Summaries of GTO Program Science Themes
Summaries of some of our work are given below by topic. These have been taken from the "science theme" section of the HETG monthly reports (date in parentheses) that were issued in this format until Sept. 2004.
