New flaring of an ultraluminous X-ray source in NGC 1365
R. Soria, A. Baldi, G. Risaliti +4
We have studied a highly variable ultraluminous X-ray source (ULX) in the Fornax galaxy NGC 1365, with a series of 12 Chandra and XMM-Newton observations between 2002 and 2006. In…
Probing the Low-Luminosity XLF in Normal Elliptical Galaxies
D. -W. Kim, G. Fabbiano, V. Kalogera +8
We present the first low luminosity (LX > 5 - 10 1036 erg s-1) X-ray luminosity functions (XLFs) of low-mass X-ray binaries (LMXBs) determined for two typical old elliptical galaxi…
Chemical enrichment of the complex hot ISM of the Antennae galaxies: I. Spatial and spectral analysis of the diffuse X-ray emission
A. Baldi, J. C. Raymond, G. Fabbiano +5
We present an analysis of the properties of the hot interstellar medium (ISM) in the merging pair of galaxies known as The Antennae (NGC 4038/39), performed using the deep, coadded…
NGC 4261 and NGC 4697: rejuvenated elliptical galaxies
A. Zezas, L. Hernquist, G. Fabbiano +1
Chandra images present evidence for a non-uniform spatial distribution of discrete X-ray sources in the elliptical galaxy NGC 4261. This non-uniform distribution is inconsistent wi…
Chandra observations of NGC4698: a Seyfert-2 with no absorption
I. Georgantopoulos, A. Zezas
We present Chandra ACIS-S observations of the enigmatic Seyfert-2 galaxy NGC4698. This object together with several other bona-fide Seyfert-2 galaxies show no absorption in the low…
X-ray luminous galaxies I. Chandra observations of IRAS00317-2142
I. Georgantopoulos, A. Zezas, M. J. Ward
We present Chandra observations of the enigmatic galaxy IRAS00317-2142, which is classified as a star-forming galaxy on the basis of the ionization level of its emission lines. How…
