SUMMARY OF SEQUENCE NUMBER 600000

Title: THE DETAILED X-RAY SPECTRA OF ELLIPTICAL GALAXIES

Observer: Wise

Subject Category: Normal Galaxies

Seq: 600000 ObsId: 02389

Long-term Plan bin: 12-May-2001

ABSTRACT

We propose to observe two elliptical galaxies NGC1399 and NGC4486 with the HETGS. Hot gas trapped in the potential well of elliptical galaxies is known to emit X-rays with a temperature that is characteristic of the depth of the potential. Cool (~1 keV) X-ray plasmas are rich in emission lines which will allow us to determine the physical state of the ISM. The temperature and abundance of the hot gas will be determined. The relative abundances of Fe and the alpha-process elements will allow us to determine the relative rate of Type I & Type II SNe supernova. In addition, X-ray emission from any nuclear sources will also be examined.
