The age distribution of 1,319 star clusters detected by a fully-automated method in the central 18 deg2 of the Small Magellanic Cloud suggests enhanced cluster formation around 240 Myr ago.

VLBA-produced total intensity and linear polarization maps are presented for 437 active galactic nuclei, ~80% of which are associated with γ-ray sources detected by the Fermi LAT instrument.

The extreme optical dropout events and large excess infrared emission of the erratically variable star RZ Piscium may be due to the recent destruction of one or more massive orbiting bodies within 1 AU of the star.
Michael O’ Riordan et al 2018 ApJ 853 44
3D GRMHD simulations of accreting black holes demonstrate significant observational differences between cases in which the funnel of an active galaxy’s jet is empty and cases where it is filled with plasma.

The inclination between the orbital angular momentum of the GW170817 binary and the line of sight is constrained to 18° ± 8° via the latest gravitational-wave, redshift, and Hubble-constant measurements.
Kyle Kremer et al 2018 ApJ 852 29
Simulations show it’s possible to form mass-transferring black-hole binaries with main-sequence, giant, and white-dwarf companions in globular clusters spanning a large range in present-day properties.
