Multiwavelength studies of galaxies with distinct asymmetric knot-plus-tail morphologies in the Hubble Ultra Deep Field suggest that these “tadpole” galaxies may be in an active phase of assembly.

Corresponding MAGIC detection of PKS 1441+25’s gamma-ray outburst: emission originates in the jet from outside the broad line region (BLR) during high activity and from within the BLR during low activity.

A. U. Abeysekara et al 2015 ApJ 815 L22

VERITAS detection of the very-high-energy gamma-ray outburst from quasar PKS 1441+25: the emission region must be located thousands of Schwarzschild radii away from the black hole.

226 young stellar objects were catalogued in the Cygnus-X DR15 region to study the interaction of young stellar populations with massive molecular cloud complexes.

Measurements of four nearby disk galaxies show that they have ~3x less stellar angular momentum than typical local spiral galaxies of the same mass — probably the main cause of their low stability.

Dale D. Kocevski et al 2015 ApJ 814 104

Heavily obscured AGN are found to be twice as likely to be hosted by late-type galaxies relative to unobscured AGN, and three times as likely to exhibit signatures of mergers or interactions.
