PCA/HEXTE Observations of M82 and NGC253The nearby starburst galaxies M82 & NGC 253 were observed by the RXTE satellite during the period February - November 1997. Data reduction and analysis began in summer 1998, and continued through March 1999. The spectral analysis indicates that the main emission in these galaxies is from hot gas. We find a considerable degree of variability in the emission from M82, possibly due to M81 (a known AGN) in the FOV. The main spectral parameters were determined for both sources. The results of the analysis were reported in the March 1999 meeting of the AAS. Summary of the data analysis, theoretical modeling, and interpretation will be presented in a paper which is currently being prepared for publication in the Astrophysical Journal.
