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.
Dougal Mackey et al 2018 ApJL 858 L21
A new panoramic imaging survey, conducted with the Dark Energy Camera, maps out the substructures and tidal distortions evident in the Magellanic periphery to constrain the interaction history of the Clouds.
Ru-Sen Lu et al 2018 ApJ 859 60
Very long baseline interferometric observations of the supermassive black hole in the galactic center, Sgr A*, suggest the presence of compact intrinsic source structure on scales of ~3 Schwarzschild radii.
Setthivoine You et al 2018 ApJS 236 29
The Mochi LabJet, a laboratory astrophysics experiment, was used to demonstrate the process of astrophysical jet production by mimicking conditions of an accretion disk threaded by a poloidal magnetic field.
Z. Arzoumanian et al 2018 ApJ 859 47
11 years of data from NanoGRAV place constraints on a population of inspiraling supermassive black hole binaries, a network of decaying cosmic strings, and a primordial gravitational-wave background.
