Tides raised on a star by a small orbiting body can be used for planet detection. These tides show distinctly different signatures when the body is on an eccentric orbit as opposed to a circular one.

First results from the CHinese Exoplanet Searching Program from Antarctica (CHESPA) reveal 222 objects with plausible transit signals, 116 of which are plausible transiting exoplanet candidates.

A search for high-energy neutrinos associated with detections from Advanced LIGO’s first observing run yielded no significant coincident candidates, allowing constraints to be placed on the rate density of astrophysical sources.

ALMA-discovered molecular gas streams orbiting around an invisible massive object in the central region of our galaxy provide new circumstantial evidence for a wandering intermediate-mass black hole in the galactic center.
Yu Wang et al 2019 ApJ 870 132
Two X-ray bright clumps in the nearby NGC 6338 galaxy group exhibit features that suggest the group is undergoing a head-on collision that is in a stage of pre-core passage.

Jupiter analogs are more common around stars hosting super-Earths, suggesting the presence of outer gas giants doesn’t suppress the formation of inner super-Earths; instead, these populations seem to be correlated.
