Euclidean self-dual gravity: Ashtekar variables without gauge fixing

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Marc Basquens, Eduardo J. S. Villaseñor, , | Summary: The GNH method is used in this paper to study the Hamiltonian formulation of the Euclidean self-dual action. This action can be used to arrive at the complex Ashtekar formulation of General Relativity […]

Evidence for a dynamic corona in the short-term time lags of black hole X-ray binary MAXI J1820+070

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Niek Bollemeijer, Phil Uttley, Arkadip Basak, Adam Ingram, Jakob van den Eijnden | Summary: In X-ray observations of hard state black hole X-ray binaries, rapid variations in accretion disc and coronal power-law emission are correlated and show Fourier-frequency-dependent time lags. On short (~0.1 s) time-scales, these […]
