چکیده
ABSTRACT We have identified three ultraluminous X-ray sources (ULXs) hosted by globular clusters (GCs) within NGC 1316’s stellar system. These discoveries bring the total number of known ULXs in GCs up to 20. find that spectra new do not deviate from established pattern spectral behaviour other GC ULXs. The consistency for these points multiple paths formation and evolution mechanisms rare unique sources. Using now larger sample ULXs, we compare optical properties entire population across five galaxies host are quite different typical clusters. Lastly, any trend being preferentially metal-rich is strongly significant this sample.

X-ray sources in globular clusters
The twelve bright (Lx > 10 36 erg s) X-ray sources in the globular clusters have lower luminosities than the brightest sources in the bulge of our galaxy. The dim (Lx < 10 35 erg s) X-ray sources in globular clusters reach higher luminosities than the cataclysmic variables in the disk of our galaxy. The first difference is a statistical fluke, as comparison with M 31 indicates. The second diffe...
متن کاملUltraluminous X-ray Sources
The Chandra X-Ray Observatory was used to image the collisional ring galaxy Arp 147 for 42 ks. We detect nine X-ray sources with luminosities in the range of (1.4–7) × 1039 erg s−1 (assuming that the sources emit isotropically) in or near the blue knots of star formation associated with the ring. A source with an X-ray luminosity of 1.4 × 1040 erg s−1 is detected in the nuclear region of the in...
متن کاملX - ray sources in ω Centauri and other globular clusters
X-ray bursts from bright sources in globular clusters of our galaxy show that at least 11 (of a total 13) of these sources are neutron stars. One of the low-luminosity X-ray sources in ω Cen is a neutron star accreting at a low rate. Together with the discoveries that M 15 contains two bright X-ray sources, and that 47 Tuc and NGC 6440 contain 2 and 5 low-luminosity X-ray sources with a neutron...
متن کاملMultiple and variable X - ray sources in the globular clusters
We detect stars from the Hipparcos and Tycho Catalogues in the field of view of observations with the ROSAT HRI of three globular clusters. We use the positions of these stars to reduce the systematic error in the positions of X-ray sources in the clusters to ∼ 2′′ for ω Cen and NGC 6752, and 1′′ for NGC 6397. We detect three X-ray sources in the core of ω Cen, and four in the core of NGC 6752;...
متن کاملChandra X - ray Observations of NGC 1316 ( Fornax A )
2 Abstract We report the results of the Chandra ACIS sub-arcsecond resolution X-ray observation of the archetypal merger radio galaxy NGC 1316 (Fornax A). We confirm the presence of fine sub-structures in the hot Interstellar Medium (ISM). Some of these are likely to result from interaction with the radio jets, while others may be related to a complex intermingling of different phases of the IS...
