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.

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.

VRI spectrophotometry of 1003 main-belt asteroids suggests a population with an average elongation b/a = 0.74 ± 0.07 and also shows that this is independent of asteroid size and taxonomy.

The combined tidal torques on an exoplanet from a moon and its parent star can force the planet to spin asynchronously with respect to both its moon and its host, tidally heating the exoplanet.

J. Christopher Mihos et al 2018 ApJL 863 L7

In the Leo I group, BST1047+1156, the lowest surface brightness object ever detected via integrated light, may be a disrupting tidal dwarf or a preexisting galaxy with a recent burst of star formation.

A very large star-forming galaxy, G6025, has been discovered and confirmed at z = 3.721; curiously, its stellar population parameters and dust reddening are are similar to those of smaller galaxies at comparable redshifts.
