Probing the X-Ray Binary Populations of the Ring Galaxy NGC 1291
B. Luo, G. Fabbiano, T. Fragos +7
We present Chandra studies of the X-ray binary (XRB) populations in the bulge and ring regions of the ring galaxy NGC 1291. We detect 169 X-ray point sources in the galaxy, 75 in t…
The Eclipsing ULX in NGC 3379
G. Fabbiano, D. -W. Kim, T. Fragos +9
We report recent Chandra observations of the ULX in the elliptical galaxy NGC3379 that clearly detect two flux variability cycles. Comparing these data with the Chandra observation…
Unveiling the AGN powering the "Composite" Seyfert/Star-forming galaxy NGC 7679: BeppoSAX and ASCA results
R. Della Ceca, S. Pellegrini, L. Bassani +5
We discuss BeppoSAX observations and archive ASCA data of NGC 7679, a nearby, nearly face-on SB0 galaxy in which starburst and AGN activities coexist. The X-ray observations reveal…
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…
