- It was not obvious at a glance which paper dealt with M87. Can you be
- more specific?
-
- The most likely place to find the supermassive stars in these galaxies
- is the core, which apparently was not imaged. After collapse, supernova, and
- high-speed ejection, such objects will not remain *in* their parent galaxies
- for long. They will be found in the neighborhood. By that stage, the light
- will no longer have a strong UV component either, because of the collapse and
- shielding effects.
-
- How about a UIT composite image of the core of these galaxies? I would
- expect a UV excess to be found there, although I have not yet found a way to
- predict its strength as a function of galaxy type. -|Tom|-
