Keck Cosmic Web Imager spectroscopy of the four putative images of the lensed quasar candidate J014710+463040 verify the source as a quasar at z = 2.377, for which all four source images are very bright.
Christian R. Hayes et al 2018 ApJL 859 L8
Chemical analysis of the Triangulum-Andromeda (TriAnd) system — a low-latitude Milky Way overdensity — suggest that it’s associated with the galactic disk, and, therefore, that the disk extends out beyond 24 kpc.

A model is introduced to describe the evolution of galaxy number counts, morphologies, and spectral energy distributions across a wide range of redshifts and stellar masses.

Under conditions expected during superflares, the continuum brightening due to extended loop arcades can significantly contribute to stellar flux detected by Kepler on M-dwarf and solar-type superflare stars.
Geoffrey C. Bower et al 2018 AJ 155 227
Submillimeter Array and Northern Extended Millimeter Array observations of the host galaxy of FRB 121102 reveal a non-detection of CO and of the continuum emission at 97 GHz, setting an upper limit on H2 mass.
Hai-Hui Zhao et al 2018 ApJ 859 106
Decades of X-ray data for the transient ultraluminous X-ray source 3XMM J031820.8-663034 suggest it’s powered by an accreting massive stellar-mass black hole, and its outbursts are triggered by an instability.
