Hydrodynamical resimulations exploring the relationship between galaxy properties and evironment suggest that galaxies in denser environments tend to be redder and are more likely to be quenched.

T. M. C. Abbott et al 2018 ApJS 239 18

The first public data release of the Dark Energy Survey consists of optical/near-infared images from ~5000 deg² of the southern galactic cap, including nearly 400 million distinct astronomical objects.

C. Alig et al 2018 ApJL 869 L2

Hydrodynamical simulations of the Smith Cloud impact onto the gaseous Milky Way galactic disk suggest the possibility of an observable, highly localized starburst event in the far future.

Po-Feng Wu et al 2018 ApJ 868 37

The observed ages and sizes of a sample of quiescent galaxies suggests two evolutionary paths to quiescence: one with gradual shutdown of star formation, and one with rapid quenching and structural changes to the galaxy.

Analysis of Kepler planet candidates suggests that sub-Neptune-sized singles (sole detected transiting planets) and multis (planets in multi-transiting-planet systems) don’t differ in their stellar properties or planet radii.

A. Albert et al 2018 ApJL 868 L20

Ten years of ANTARES track and shower data and seven years of IceCube track data reveal no significant excess, providing new constraints on galactic cosmic-ray production and transport.
