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…
The low luminosity AGN in the LINER galaxy M81: BeppoSAX discovery of highly ionized gas
S. Pellegrini, M. Cappi, L. Bassani +3
The LINER nucleus of the nearby spiral galaxy M81 was pointed by BeppoSAX, which caught it at the highest (2-10) keV flux level observed so far. The LECS, MECS and PDS data, extend…
Global X-ray emission and central properties of early type galaxies
S. Pellegrini
Hubble Space Telescope observations revealed that the central surface brightness profiles of early type galaxies can be divided into two types: "core" profiles and featureless powe…
BeppoSAX observation of NGC3923, and the problem of the X-ray emission in E/S0 galaxies of low and medium Lx/Lb
S. Pellegrini
We present the results of the analysis of the BeppoSAX LECS and MECS pointed observation of the E4 galaxy NGC 3923, for which previous X-ray measurements had given a medium X-ray t…
