TL;DR: In this paper, the authors review the current observational standpoint for black-hole binaries and survey models that have been proposed to interpret it, and identify key observational diagnostics which can provide direct access to the dynamics of matter motions in close vicinity of black holes and thus to the fundamental properties of curved spacetimes, where strong-field general relativistic effects can be observed.

TL;DR: In this article, the Lighthouse nebula and its jet-like X-ray structure were observed through dedicated high spatial resolution observations in X-rays (Chandra) and radio band (ATCA), and it was shown that the feature is a true pulsar's jet.

TL;DR: Abbott et al. as mentioned in this paper compared the four probability sky maps produced for the gravitational-wave transient GW150914, and provided additional details of the EM follow-up observations that were performed in the different bands.

TL;DR: In this paper, the first optical spectrum of the low mass transient X-ray pulsar SAX J1808.4-3658 in quiescence was obtained using the brightness of the companion star as a bolometer, concluding that a very high irradiating luminosity must be present in the system.

TL;DR: In this article, the authors reported the detection of optical pulsations from a transitional millisecond pulsar that was surrounded by an accretion disk, and originated inside the magnetosphere or within a few hundreds of kilometres from it.
