TL;DR
This study presents deep hard X-ray observations of the Small Magellanic Cloud using INTEGRAL, revealing multiple transient high-mass X-ray binary systems, including previously unknown sources and outbursts.
Contribution
First comprehensive INTEGRAL survey of the SMC in hard X-rays, discovering new transient sources and characterizing their behavior.
Findings
Detected 7 sources in the SMC and 5 in the Magellanic Bridge.
Most sources are transient high-mass X-ray binaries with neutron stars.
Several sources exhibited bright X-ray outbursts.
Abstract
Deep observations of the Small Magellanic Cloud (SMC) and region were carried out in the hard X-ray band by the INTEGRAL observatory in 2008-2009. The field of view of the instrument permitted simultaneous coverage of the entire SMC and the eastern end of the Magellanic Bridge. In total, INTEGRAL detected seven sources in the SMC and five in the Magellanic Bridge; the majority of the sources were previously unknown systems. Several of the new sources were detected undergoing bright X- ray outbursts and all the sources exhibited transient behaviour except the supergiant system SMC X-1. They are all thought to be High Mass X-ray Binary (HMXB) systems in which the compact object is a neutron star.
