TL;DR: Observations and physical modelling of a rapidly fading electromagnetic transient in the galaxy NGC 4993, which is spatially coincident with GW170817, indicate that neutron-star mergers produce gravitational waves and radioactively powered kilonovae, and are a nucleosynthetic source of the r-process elements.

TL;DR: In this paper, the authors presented optical (MUSE) and mm (ALMA) observations of the field of the quasar Q1130−1449 which includes a log [N(H I)/cm−2] = 21.71 ± 0.07 absorber at z = 0.313.

TL;DR: In this paper, the spectral characteristics of a type-Ic supernova (SN) and signs of a hydrogen-rich circumstellar medium (CSM) were confirmed by removing the CSM interaction component from the spectrum and comparing with known SNe Ic and, reversely, adding a SNE Ic interaction component to the spectra of known SN Ic and comparing them to SN 2017dio.

TL;DR: In this article, a collection of 450 598 eclipsing and ellipsoidal binary systems detected in the OGLE fields toward the Galactic bulge is presented, consisting of binary systems of all types: detached, semi-detached, and contact eclipsing binaries, RS CVn stars, cataclysmic variables, HW Vir binaries, double periodic variables, and even planetary transits.
