  1. Chandra X-ray Data Analysis in Educational Settings Terry Matilsky, Eugenia Etkina (Rutgers University), Kathy Lestition, Eric Mandel & William Joye (CfA) How can we provide an authentic research experience to students who want to find out what science is REALLY about? We couple DS9 imaging software, a user friendly, fun to explore environment with a “virtual observatory” that allows analysis to be done remotely on UNIX based machines, regardless of the platform employed by the user. Furthermore, by adapting VNC (Virtual Network Computer) software, we can enhance this flexibility enormously and allow instructors to view, comment on, and debug any analysis task in real-time, from anywhere in the world, and across all computing platforms. This makes these programs especially useful in distance learning environments. DS9 http://chandra-ed.harvard.edu DS9-Continued Now we can do some real science! PICK TWO REGIONS BOX 1 BOX 2 DS9 From this image, we can perform a host of operations: OR GET ENERGY SPECTRA! CHANGE COLORS CHANGE CONTRAST DISPLAY COORDINATE SYSTEMS TIME VARIABILITY ANALYSIS USING CEN X-3 POWER SPECTRUM LIGHT CURVES EQUATORIAL GALACTIC CREATE ANALYSIS REGIONS Very flexible! You can even select regions based on iso-intensity contours FOLDED LIGHT CURVE ZOOM IN!!! BOX 3 VNC- Virtual Network Computing allows you to view any computer (in this case, a LINUX server at Rutgers that contains the entire suite of DS9 and FTOOLS subroutines), even if you are in a PC environment. Moreover, students can work from several remote locations and see the same window. The instructor can now “debug” or comment on any work , also from a remote location. For example, you can examine any number of VNC sessions, and comment (in real time) on a students work. You can operate the mouse and keyboard remotely, and the student will see it on his/her desktop! We have been using these tools for 7 years in our annual month long Astrophysics Summer Institute held each year at Rutgers University. See the handout for more information, and GO TO GADGETS AND GIZMOS FOR A LIVE DEMO!!
