SINGS comparison
+ NeIII/NeII ratio vs O/H abundance
+ Galactic center is moderately inconsistent with AGN
Other line ratios (FeII/NeII vs SiII/SIII) - GC offset from AGNagain
+ Most CMZ points look like "normal" star forming regions
+ lots of scatter, but trend with longitude
photoionization by hot stars & shocks explain colors
Questions
Q: Is there any significance to the idea that high-latitude are most similar
to AGN?
A: ...didn't understand question... talked about oxygen abundance
determinations and statistical significance
Q: Is there any physical significance to the high-latitude points having
AGN colors? Could it be from AGN being "turned off" years ago?
A: you tell me. Could be X-ray binaries, wolf-rayet stars. No clear
evidence that Sgr A* excited it.
Q: Need bright source. XRBs would have to be very bright.
A: Our obs don't show much. Distance unknown. Could be foreground.
Q Stocke: - detections of Ne V. Couldn't see. How many had Ne V definitely
detected? In infrared or diffuse?
A: ~12 out of 400 detected. Mostly Ne V in ISM, not in point sources.
Q Farhad: What does # of detected YSOs tell you about SFR? How are they
distributed in plane?
A: Consistent with Schmidt law. Not far from Farhad's measurement.
YSOs selected on IR photometry. 50% of sources from near Sgr B.
