An overview of SDSS-IV is provided, including its major spectroscopic programs: APO Galactic Evolution Experiment 2, Mapping Nearby Galaxies at APO, and extended Baryon Oscillation Spectroscopic Survey.
Adam Smercina et al 2017 ApJL 843 L6
New observations with the Subaru Hyper Suprime-Cam identify a new dwarf galaxy that may be a satellite of BK5N, which is in turn a satellite of M81. This may be one of the first detected satellites-of-a-satellite.

New VLBA and VLA observations show that the decay of radio flux after the tidal disruption event IGR J12580+0134 in 2010 is consistent with predictions from a jet-circumnuclear medium interaction model.

Three-dimensional magnetohydrodynamic simulation of the solar wind are used to calculate cosmic-ray diffusion coefficients throughout the inner heliosphere (i.e., from 2 solar radii to 3 AU).

Four occultation measurements of the plutino object (208996) 2003 AZ84 reveal that it is a triaxial body with a topographic feature that may be an abrupt chasm 23 km wide and at least 8 km deep.
G. Yang et al 2017 ApJ 842 72
The sample of 18,000 galaxies in the CANDELS/GOODS-South field ( 0.5 ≤ z ≤ 2.0) suggest that the black hole accretion rate is more strongly correlated with host galaxy stellar mass than with star formation rate.
