The Chandra survey of the SMC "Bar": II. Optical counterparts of X-ray sources
Vallia Antoniou, Andreas Zezas, Despina Hatzidimitriou +1
We present the most likely optical counterparts of 113 X-ray sources detected in our Chandra survey of the central region of the Small Magellanic Cloud (SMC) based on the OGLE-II a…
The XMM-Newton long look of NGC 1365: uncovering of the obscured X-ray source
G. Risaliti, M. Salvati, M. Elvis +10
We present an analysis of the extreme obscuration variability observed during an XMM-Newton 5-days continuous monitoring of the AGN in NGC 1365. The source was in a reflection-domi…
Exploring the Small Magellanic Cloud to the Faintest X-ray Fluxes: Source Catalog, Timing and Spectral Analysis
Silas Laycock, Andreas Zezas, Jaesub Hong +2
We present the results of a pair of 100 ksec Chandra observations in the Small Magellanic Cloud to survey high mass X-ray binaries (HMXBs), stars and LMXBs/CVs down to Lx = 4.3 x 1…
Discovery of Hot Gas in Outflow in NGC3379
G. Trinchieri, S. Pellegrini, G. Fabbiano +10
We report the discovery of a faint (L_x ~ 4 10^37 erg/s, 0.5-2 keV), out-flowing gaseous hot interstellar medium (ISM) in NGC 3379. This represents the lowest X-ray luminosity ever…
New insights into the X-ray properties of the nearby barred spiral galaxy NGC 1672
L. P. Jenkins, W. N. Brandt, E. J. M. Colbert +4
We present some preliminary results from new Chandra and XMM-Newton X-ray observations of the nearby barred spiral galaxy NGC1672. It shows dramatic nuclear and extra-nuclear star…
Models for Low-Mass X-Ray Binaries in the Elliptical Galaxies NGC3379 and NGC4278: Comparison with Observations
T. Fragos, V. Kalogera, K. Belczynski +11
We present theoretical models for the formation and evolution of populations of low-mass X-ray binaries (LMXB) in the two elliptical galaxies NGC 3379 and NGC 4278. The models are…
