The IAU recommends nominal conversion constants for selected solar and planetary properties (e.g. solar radius, luminosity, and mass, or Jupiter’s radius) in order to standardize regerence values.

The stellar kinematics of Dragonfly 44, one of the largest Coma ultra-diffuse galaxies (UDGs), reveal a dark matter fraction of 98%, adding to recent evidence that UDGs are “failed” galaxies.

Simulations of accretion flows around stellar mass black holes show that the relatively cold disk (107 K) is truncated near the black hole. Hot, low-density regions appear within the truncation radius.
Dennis Zaritsky et al 2016 ApJ 826 L9
Based on the discovery of a globular cluster in ultra-faint Eri II, it’s calculated that subhalos with M < 1010 solar masses, many of which may be yet undetected, could host between 5 and 31 globular clusters.

The 3D-HST Treasury program has produced a comprehensive photometric and spectroscopic wide-field data set for studies of the distant universe. Observations and data products are described here.

95 candidate VELLOs, objects with low-luminosity embedded in dense cores, were found. They may be in quiescent phases of a cycle of episodic mass accretion, explaining their low luminosity.
