ALMA observations of the low-luminosity active galactic nucleus of NGC 1097 reveal a lack of a dense and compact cold molecular torus, implying less active nuclear star formation and/or inflows in NGC 1097.

The bias of observations of Kuiper-belt-object (KBO) clustering is assessed. While observational bias is shown to be present, it is unlikely to explain the observed alignment of distant eccentric KBOs.

ALMA observations uncovered the strongly misaligned, dusty disks of a young triple system of protostars, SR24, and revealed information about their sizes, inclinations, and rotation directions.

Simulations show that protoclusters — extended structures containing numerous star-forming galaxies — may have been crucial in driving the timing and topology of cosmic reionization.
Moupiya Maji et al 2017 ApJ 844 108
High-resolution hydrodynamical simulations of interacting galaxies suggest that gas-rich galaxy mergers can provide a favorable environment for the formation of massive star clusters such as globular clusters.

Imaging and spectroscopy of three dwarf elliptical galaxies in the Virgo Cluster confirm the presence of significant reservoirs of H I that are unlikely to have been recently accreted.
