Chandra and NuSTAR ToO observations of Swift X-ray transients in the Galactic Center
Abstract
We propose Chandra and NuSTAR follow-up observations of new X-ray transients and recurrent outbursts from the known VFXTs (very faint X-ray transients), detected by Swift-XRT, at r < 50 pc from the Galactic Center. The accurate source localization by Chandra and broad-band spectral/timing data with NuSTAR provide the useful diagnostic tools of understanding the nature of X-ray transients in the Galactic Center, as demonstrated by four Swift transients followed up by Chandra and NuSTAR including the transient magnetar SGR J1745-2900, one VFXT and two new black hole transients. Detecting and characterizing new X-ray transients, together with investigating quiescent X-ray binaries, will probe the population and formation of X-ray binaries near Sgr A*.
