Repetitive Patterns in Rapid Optical Variations in the Nearby Black-hole Binary V404 Cygni

Kavli Affiliate: Stuart L. Marshall | First 5 Authors: Mariko Kimura, Keisuke Isogai, Taichi Kato, Yoshihiro Ueda, Satoshi Nakahira | Summary: How black holes accrete surrounding matter is a fundamental, yet unsolved question in astrophysics. It is generally believed that matter is absorbed into black holes via accretion disks, the state of which depends primarily […]

Evidence for simultaneous jets and disk winds in luminous low-mass X-ray binaries

Kavli Affiliate: Norbert Schulz | First 5 Authors: Jeroen Homan, Joseph Neilsen, Jessamyn L. Allen, Deepto Chakrabarty, Rob Fender | Summary: Recent work on jets and disk winds in low-mass X-ray binaries (LMXBs) suggests that they are to a large extent mutually exclusive, with jets observed in spectrally hard states and disk winds observed in […]

S-folds and 4d N=3 superconformal field theories

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Ofer Aharony, Yuji Tachikawa, Kiyonori Gomi, , | Summary: S-folds are generalizations of orientifolds in type IIB string theory, such that the geometric identifications are accompanied by non-trivial S-duality transformations. They were recently used by Garcia-Etxebarria and Regalado to provide the first construction of four dimensional N=3 […]
