SUMMARY OF SEQUENCE NUMBER 600102
Title: HOT AND COLD GAS, DARK MATTER, AND HEAVY ELEMENTS IN ELLIPTICAL GALAXIES
Observer: JONES
Subject Category: Normal Galaxies
Seq: 600102 ObsId: 00799
Long-term Plan bin: 29-Dec-1999
ABSTRACT
We propose to observe NGC1395, a low X-ray luminosity, "normal" elliptical (E2) galaxy with a rotation velocity of ~100 km/sec to address four fundamental questions. How much dark matter is in its halo? What is the source of the ``hard'' spectral component found in ASCA observations of elliptical galaxies? What are the heavy element abundances in the X-ray gas, what is the abundance distribution, and what do these imply about the supernova enrichment history? Do central cooling flows occur in low luminosity, rotating galaxies?
