2. Cataclysmics In Core Of Globular Cluster NGC6397 - ROSAT Image vs. CXO Simulation In 3-D Projection
ROSAT data, left, suggests several sources. AXAF simulation shows how 20x better angular resolution allows sources to be resolved.
(Simulation: CXC)

3. Cataclysmics In Core Of Globular Cluster NGC6397 - HST Field
Superimposed circles mark ROSAT positions. Smaller circles around proposed CXO positions. CXO positions offset slightly to correspond to proposed optical IDs. Note #'s of candidates (1 or 2) for CXO vs. 10's for ROSAT.
(Simulation: CXC)

4. Trapezium Star Cluster, ROSAT Observation vs. CXO Simulation
ROSAT observation (left) detects ~70 sources - PMS stars down to brown dwarfs (possibly). ACIS (right) simulation finding and resolving ~8x more sources, shows gain from CXO.
(Simulation: CXC)

5. Trapezium Star Cluster, K-Band Observation vs. CXO Simulation
K-band observation - left; CXO simulation - right. Most of the stars in the cluster can be detected and identified by CXO- very young stars, will study hundred to 1000. Can see flares in a day's observation, measure temperatures etc.
(Simulation: CXC / HST)

11. Galaxy Cluster A1367 Optical Vs. X-Ray Picture
Optical image is a ground-based picture showing fuzzy, extended galaxies in cluster as well as foreground stars. X-ray image from HEAO-2/Einstein showing patchy, diffuse emission from 10/7th-10/8th degrees K gas filling the space between the galaxies.
