A clear correlation is found between black-hole mass and host galaxy total stellar mass using 262 broad-line AGN in the nearby universe — useful for cases when the stellar bulge can’t be resolved.
F. Yusef-Zadeh et al 2015 ApJ 811 L35
Emission from SGR J1745-2900, the magnetar at the galactic center, may have been due to the interaction between the shock generated by its X-ray outburst, and the ionized gas cloud G2.

The properties of the ultra-compact dwarf galaxy M59-UCD3 in the nearby Virgo Cluster suggest that it may represent an extreme population of tidally stripped galaxies.
Tilman Birnstiel et al 2015 ApJ 813 L14
Gaps observed in NIR images of protoplanetary disks could be due to dust evolution rather than the presence of planets. Longer-wavelength observations can differentiate between the two mechanisms.
Lixin Dai et al 2015 ApJ 812 L39
High-temperature vs. low-temperature tidal disruption events may be produced when the tidal debris stream of the disrupted star intersects itself close to vs. far from the black hole.
Ruobing Dong (董若冰) et al 2015 ApJ 812 L3
Protoplanetary disks with disk-to-star-mass ratios of <0.25 may produce prominent spiral arms in NIR imaging, induced by gravitational instability in the disk.
