An investigation of the dynamics of the galaxy cluster A2142 reveal 868 members and a number of substructures in the galaxy distribution that suggest multiple minor mergers in this cluster’s past.

Analysis of radial-velocity observations of Kepler data indicates that cold Jupiters appear three times more often around hosts of super Earths than they do around field stars.
K. D. Alexander et al 2018 ApJL 863 L18
New observations of the binary neutron star merger GW170817 at Δt ≈ 220–290 days post-merger support models of a successful structured jet expanding into a low-density circumbinary medium.

Using data mining in wide-field sky surveys, scientists have identified a sample of 305 intermediate-mass black hole candidates and confirmed the active galactic nucleus nature of 10 of these sources.

Jansky VLA observations of a sample of five known radio-emitting late-L and T dwarfs suggest that age, mass, and temperature together cannot account for the strong magnetic fields produced by the targets.

A newly discovered late-B-type unbound hyper-runaway star (LAMOST-HVS4) was probably ejected from the galactic disk by supernova explosion or multiple-body interactions in dense young stellar clusters.
