Transient radio emission was discovered from the tidal disruption event ASASSN-14l. This first-ever radio detection for a typical TDE provides evidence for the formation of a non-relativistic outflow.

One issue with the continuum-fitting method for estimating black-hole spin is the apparent decrease in spin with increasing source luminosity. This can be resolved by assuming the presence of a disk wind.

Saturn’s moon Atlas exhibits a chaotic orbit whose dynamics are primarily controlled by resonant perturbations from the moon Prometheus. This may be common in satellite evolution around giant planets.

A set of machine-learning tools are shown to be useful for automatically differentiating between stars and galaxies in large survey catalogs, and also for estimating photometric redshifts of galaxies.

Optical observations of V404 Cyg prior to its X-ray outburst suggest this black hole’s disk entered the hot, outburst state before the X-ray outburst. The event may have been triggered by a disk instability.

NIR Hubble observations of Orion molecular clouds reveal that the fraction of stars with 100-1000 AU companions is ~50% higher in the high-stellar-density regions, relative to the low-density regions.
