Gravity harmonics measured during the Cassini Grand Finale may be used to get an estimate of the structure of how Saturn’s gas flows and to better constrain the planet’s density structure and composition.

The Subhalo and PARticle Trajectory Analysis (SPARTA) parallel computer code can analyze the orbits of billions of particles in large cosmological simulations of dark matter halos, reliably measuring halo properties.

New computational advancements have been made in time–distance helioseismology, a process that allows us to infer internal properties of the Sun from surface measurements of wave travel times.
Takashi J. Moriya et al 2017 ApJL 843 L19
The superluminous transients that appear at central regions of some active galactic nuclei may be powered by the interaction between accretion-disk winds and clouds in broad-line regions surrounding them.

The relative motion of the two cores of a supermassive black hole binary is measured in radio galaxy 0402+379 and used to constrain the system. This is the first black hole system resolved as a visual binary.
