George B. Lansbury et al 2018 ApJL 856 L1
Chandra X-ray observations of the “Teacup AGN” (SDSS J1430+1339), a z = 0.085 type 2 quasar, reveal details of the quasar’s dramatic interaction with its host galaxy.

High-resolution hydro and MHD simulations indicate that, under solar neighborhood conditions, external supernova explosions are not sufficient to explain the observed level of turbulence in molecular clouds.

The light curve of the microlensing event MOA-2010-BLG-117 can be explained by the gravitational lensing of a binary source star system by a star with a Jupiter-mass ratio planet.

A loose coupling is found between star formation history and black hole mass in a sample of 127 low-mass galaxies, seemingly suggesting that AGN activity does not dominate baryonic cooling in such galaxies.

New Hubble multi-wavelength photometric catalogs are presented for the Hubble Frontier Fields and associated parallels; additional data further expand these catalogs, forming a robust total data set for the Fields.
Richard R. Radick et al 2018 ApJ 855 75
Patterns of variation for the Sun and 72 Sun-like stars are explored through nearly three decades of data. The Sun appears to be somewhat unusual in its comparatively smooth, regular activity cycle.
