TL;DR: The Advanced Telescope for High Energy Astrophysics (Athena+) mission as discussed by the authors provides the necessary performance (e.g., angular resolution, spectral resolution, survey grasp) to address these questions and revolutionize our understanding of the Hot and Energetic Universe.

TL;DR: eXTP as discussed by the authors is a science mission designed to study the state of matter under extreme conditions of density, gravity and magnetism, which carries a unique and unprecedented suite of state-of-the-art scientific instruments enabling for the first time ever the simultaneous spectral-timing-polarimetry studies of cosmic sources in the energy range from 0.5-30 keV.

TL;DR: In this article, it was shown that the two high frequency QPOs in Sco X-1 are, more often than not, approximately in the 2:3 frequency ratio familiar from studies of black hole candidates.

TL;DR: In this paper, a scheme for incorporating vertical radiative energy transport into a fully relativistic, Kerr-metric model of optically thick, advective, transonic alpha disks was proposed.
