Broad band properties of medium and low Lx/Lb Early Type Galaxies
G. Trinchieri, S. Pellegrini, A. Wolter +2
We have measured the spectral properties of five galaxies of low to intermediate Lx/Lb ratios with BeppoSAX and ASCA. A hard component (kT ~4-10 keV) is observed in all galaxies. I…
Observations of the Galactic Center Region with Beppo-Sax
L. Sidoli, S. Mereghetti
We are performing a survey of the Galactic Center region with the BeppoSAX satellite. Several known point sources are visible (including one at the position of SgrA*), as well as n…
BeppoSAX confirms extreme relativistic effects in the X-ray spectrum of MCG-6-30-15
M. Guainazzi, G. Matt, S. Molendi +8
We report the first simultaneous measure of the X-ray broadband (0.1--200 keV) continuum and of the iron K-alpha fluorescent line profile in the Seyfert 1 galaxy MCG-6-30-15. Our d…
The stellar content of the Sagittarius Dwarf Galaxy
G. Marconi, R. Buonanno, M. Castellani +4
We present V,I deep CCD photometry for three fields of the dwarf galaxy in Sagittarius (Sgr). One of the fields is centered on the globular cluster NGC 6715 (M54), which lies in on…
