Continued public INTEGRAL Target of Opportunity observations of V404 Cyg (GS2023+338)
Abstract
The black-hole X-ray transient V404 Cyg (GS 2023+338) recently entered a new outburst (e.g., GCN #17929, ATels #7646, #7647). The extreme brightness of the transient in (hard) X-rays (GCNs #17929, #17932, #17935, #17938, #17943, #17944, #17945, #17946, #17948, #17949; ATels #7646, #7647, #7662, #7665, #7693, #7694) makes this a unique event, and INTEGRAL is the only observatory currently capable of doing high-resolution gamma-ray spectroscopy.
