Abstract:
We report INTEGRAL IBIS γ-ray and VLA radio observations of G0.570-0.018, a diffuse X-ray source recently discovered by ASCA and Chandra in the Galactic center region. Based on its spectrum and morphology, G0.570-0.018 has been proposed to be a very young supernova remnant. In this scenario, the presence of γ-ray lines coming from the short-lived radioactive nucleus 44Ti and synchrotron radio continuum emission are expected. The first could provide information on nucleosynthesis environments in the interior of exploding stars, and the latter could probe the interaction between the supernova blast wave and the circumstellar/interstellar matter. We have not detected 44Ti lines or any conspicuous radio feature associated with this source down to the achieved sensitivities. From the derived upper limits we set constraints on the nature of G0.570-0.018. © 2006. The American Astronomical Society. All rights reserved.
