The Magellanic Bridge: evidence for a population of X-ray binaries

The Magellanic Bridge: evidence for a population of X-ray binaries
INTEGRAL observations of the Small Magellanic Cloud region have resulted in the serendipitous detection of two transient hard X-ray sources in the Magellanic Bridge. In this paper, we present the timing and spectral characteristics of these sources across the 2-100?keV energy range, which, in conjunction with their optical counterparts, demonstrate that they are high-mass X-ray binaries (HMXBs) in the Magellanic Bridge. Together with one previously known HMXB system, and three candidates, these sources represent an emerging population of X-ray binaries in the Bridge, probably initiated by tidally induced star formation as a result of the gravitational interaction between the Large and Small Magellanic Clouds.

Abstract

INTEGRAL observations of the Small Magellanic Cloud region have resulted in the serendipitous detection of two transient hard X-ray sources in the Magellanic Bridge. In this paper, we present the timing and spectral characteristics of these sources across the 2-100?keV energy range, which, in conjunction with their optical counterparts, demonstrate that they are high-mass X-ray binaries (HMXBs) in the Magellanic Bridge. Together with one previously known HMXB system, and three candidates, these sources represent an emerging population of X-ray binaries in the Bridge, probably initiated by tidally induced star formation as a result of the gravitational interaction between the Large and Small Magellanic Clouds.
