43 years of spectroscopic observations of the Seyfert 1 galaxy NGC 5548 reveal a ~5700 day periodicity in its light curves, consistent with orbital motion inside the broad emission line region of the source.

An XMM-Newton search of two subdwarfs and a subgiant suggests that coronal activity decreases with age among the oldest G dwarfs, but K-M subdwarfs possibly have maintained a solar-like level of activity.

G. Barro et al 2016 ApJ 827 L32

ALMA dust continuum observations of six dusty star-forming galaxies at z ~ 2.5 suggest that strong nuclear starbursts transform larger, star-forming progenitors into compact quiescent galaxies.

VLBI observations indicate that the brightness temperature increases with increasing distance on sub-parsec scales in compact radio jets, suggesting that the jets are accelerated in these sub-parsec regions.

A statistical analysis of the 51,406 stars in the Kepler field spectroscopically observed with LAMOST found 106 candidate metal-poor stars, 9 candidate very metal-poor stars, and 18 candidate high-velocity stars.

Simulations of galactic outflows from supernova explosions demonstrate that inclusion of cosmic-ray physics changes the source of pressure that provides the driving force for the outflows.
