Igor V. Chilingarian et al 2018 ApJ 863 1

Using data mining in wide-field sky surveys, scientists have identified a sample of 305 intermediate-mass black hole candidates and confirmed the active galactic nucleus nature of 10 of these sources.

Melodie M. Kao et al 2018 ApJS 237 25

Jansky VLA observations of a sample of five known radio-emitting late-L and T dwarfs suggest that age, mass, and temperature together cannot account for the strong magnetic fields produced by the targets.

Yin-Bi Li et al 2018 AJ 156 87

A newly discovered late-B-type unbound hyper-runaway star (LAMOST-HVS4) was probably ejected from the galactic disk by supernova explosion or multiple-body interactions in dense young stellar clusters.

Qian Yang et al 2018 ApJ 862 109

21 new changing-look active galactic nuclei — AGN that exhibit the appearance or disappearance of broad Balmer emission lines within a few years — have been discovered, doubling the number of these objects known.

S. Ansoldi et al 2018 ApJL 863 L10

MAGIC very-high-energy observations of the blazar TXS 0506+056, combined with detailed jet modeling, corroborate a connection between the object’s high-energy radiation and the neutrino detected from its direction.

M. Lazzarini et al 2018 ApJ 862 28

Multiwavelength observations from NuSTAR, Chandra, and Hubble are used to infer compact object type, spectral type of the donor star, and age for 15 high-mass X-ray binary candidates in the disk of M31.
