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…
X-ray supernova remnants in nearby galaxies
Ioanna Leonidaki, Andreas Zezas, Panayotis Boumis
We present the initial results from a study of the SNR population in a sample of six nearby galaxies (NGC 2403, NGC 4214, NGC 4449, NGC 5204, NGC 3077, NGC 4395) based on Chandra a…
The Dearth of low-luminosity Globular Cluster LMXBs in NGC 3379
G. Fabbiano, N. J. Brassington, A. Zezas +10
Our campaign of deep monitoring observations with {\it Chandra} of the nearby elliptical galaxy NGC 3379 has lead to the detection of nine globular cluster (GC) and 53 field low ma…
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…
The Far Ultraviolet Spectroscopic picture of the Missing Baryons in the Local Group
F. Nicastro, A. Zezas, M. Elvis +6
The number of detected baryons in the low-redshift Universe (z < 1) is far small er than the corresponding number of baryons observed at higher redshift. According to hydrodynamica…
