Inertial active chains show multiple dynamical crossovers
This research indicates that inertial active particles in a one-dimensional chain can switch between ballistic, diffusive, and subdiffusive motion while also showing non-Gaussian fluctuations over time.

Vertical flows are detected in most protoplanetary disks
This research indicates that vertical gas motions are common in protoplanetary disks, with some disks showing patterns linked to instabilities or the bases of disk winds.

Cored stellar systems can persist in cuspy dark matter halos
This research indicates that cored stellar systems can remain stable inside cuspy dark matter halos for at least several Hubble times, and that ultrafaint dwarf galaxies do not let observers distinguish among mildly positive, flat, or negative inner density slopes.
