Chandra discovery of activity in the quiescent nuclear black hole of NGC821
A. Baldi, G. Fabbiano, S. Pellegrini +4
We report the results of the Chandra ACIS-S observations of the elliptical galaxy NGC 821, which harbors a supermassive nuclear black hole (of 3.5x10^7 solar masses), but does not…
First results from a Chandra survey of the 'Bar' region of the SMC
A. Zezas, J. C. McDowell, D. Hadzidimitriou +3
We present the first results from a Chandra survey of the central region of the Small Magellanic Cloud. We detect a total of 122 sources down to a limiting luminosity of ~4.3x10^{3…
Deep ROSAT-HRI observation of the elliptical galaxy NGC 1399
M. Paolillo, G. Fabbiano, G. Peres +1
We present the preliminary results of a deep (167 ks) ROSAT HRI observation of the cD galaxy NGC1399 in the Fornax cluster. We find, in agreement with previous observations, an ext…
Spectra and evolution of two X-ray sources in M81
V. La Parola, G. Fabbiano, D. W. Kim +1
We analyzed the spectral and temporal features of X-ray sources in M81 using data from the relevant ROSAT-PSPC/HRI observations. We discuss the main features of the point-like nucl…
How do we Build Future X-ray Observatories to Study Galaxies?
G. Fabbiano
Galaxies are key objects for the study of cosmology, the life cycle of matter, and stellar evolution. X-ray observations have given us a new key window into these building blocks o…
