11 Oct 2007 | | Abstract: | We have detected 523 sources in a survey of the Small Magellanic Cloud (SMC)
Wing with Chandra. By cross-correlating the X-ray data with optical and
near-infrared catalogues we have found 300 matches. Using a technique that
combines X-ray colours and X-ray to optical flux ratios we have been able to
assign preliminary classifications to 265 of the objects. Our identifications
include four pulsars, one high-mass X-ray binary (HMXB) candidate, 34 stars and
185 active galactic nuclei (AGNs). In addition, we have classified 32 sources
as ’hard’ AGNs which are likely absorbed by local gas and dust, and nine ’soft’
AGNs whose nature is still unclear. Considering the abundance of HMXBs
discovered so far in the Bar of the SMC the number that we have detected in the
Wing is low. | | Source: | arXiv, 0710.2232 | | Services: | Forum | Review | PDF | Favorites | |
