New outburst of the black-hole low-mass X-ray binary GX 339-4 detected with XB-NEWS and Swift/XRT
Abstract
GX 339-4 is a black-hole low-mass X-ray binary undergoing outbursts with recurrence times of approximately 1-2 years. During the last few months, GX 339-4 has shown low-level X-ray and optical activity, with fluxes slightly higher than those normally observed in quiescence (ATel #16096).
