William Janesh et al 2015 ApJ 811 35

A possible optical counterpart to ultra-compact high velocity cloud AGC 198606 has been detected by the ALFALFA survey, supporting the idea that this may be a low-mass dwarf galaxy.

S. Riemer-Sørensen et al 2015 ApJ 810 48

The first search for dark matter line emission in the 3-80 keV range, in the form of a pointed observation of the Bullet Cluster with NuSTAR, yielded no detection.

Eugene Vasiliev et al 2015 ApJ 810 49

Simulations show that without collisional relaxation, axisymmetric galaxies still exhibit the final-parsec problem, but in tri-axial galaxies the binary can coalesce in <1 Gyr.

Chen-Xu Liu et al 2015 ApJ 810 165

This study of ~76k void galaxies shows that void galaxies are slightly fainter, are less massive, have younger stellar populations, and have higher specific star formation rates than wall galaxies.

Tie Liu et al 2015 ApJ 810 147

A high-velocity molecular outflow has been detected in the mini-starburst W49N. Among the most energetic molecular outflows in the Milky Way, this could shed light on high-mass star formation.

Jeremy Heyl et al 2015 ApJ 810 127

A study of globular cluster 47 Tucanae suggests that stars similar to the Sun lose the majority of their mass to become white dwarfs as they reach the AGB phase, NOT when they are red giants.
