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…
New XMM-Newton analysis of three bright X-ray sources in M31 globular clusters, including a new black hole candidate
R. Barnard, H. Stiele, D. Hatzidimitriou +6
We present detailed analysis of three globular cluster X-ray sources in the XMM-Newton extended survey of M31. The X-ray counterpart to the M31 globular cluster Bo 45 (XBo 45) was…
A deep XMM-Newton survey of M 31
H. Stiele, W. Pietsch, F. Haberl
The deep homogeneous survey of the large Local-Group spiral galaxy M 31 is a milestone project for X-ray astronomy, as it allows a detailed X-ray inventory of an archetypal low-sta…
M31N 2005-09c: a fast FeII nova in the disk of M31
D. Hatzidimitriou, P. Reig, A. Manousakis +3
Classical novae are quite frequent in M~31. However, very few spectra of M31 novae have been studied to date, especially during the early decline phase. Our aim is to study the pho…
Spectroscopy of the brightest optical counterparts of X-ray sources in the direction of M~31 and M~33
D. Hatzidimitriou, W. Pietsch, Z. Misanovic +2
Recent surveys of the Local Group spiral Galaxies M31 and M33 with XMM-Newton yielded a large number of X-ray sources. As part of the effort to identify and classify the objects re…
On the Properties of the HI shells in the Small Magellanic CLoud
D. Hatzidimitriou, S. Stanimirovic, F. Maragoudaki +3
There are 509 expanding neutral hydrogen shells catalogued in the Small Magellanic Cloud (SMC), all apparently very young, with dynamical ages of a few Myr. To examine their relati…
