Simulations show that the hot plasma found in the halo of the Milky Way could solely originate from winds driven by star formation feedback in the galactic disk.
Yongjung Kim et al 2015 ApJ 813 L35
The recent discovery of a faint quasar at z ~ 6 suggests that the number of quasars at this redshift may not be high enough to fully account for the reionization of the universe by quasars alone.

The Triangulum II galaxy has been identified as being dark-matter dominated. If it is in dynamical equilibrium, then it has the largest mass-to-light ratio of any non-disrupting galaxy known.
Liang Zhang et al 2015 ApJ 813 90
Swift/XRT and NuSTAR observations of black-hole candidate XTE J1908+094, during its 2013–2014 outburst, suggest the presence of an advection-dominated slim disk and relativistic jets.

After CMEs travel a distance of roughly 10 solar radii, the background solar wind has negligible influence on their deflection and they propagate with roughly constant angular momentum.

Transiting planets have been found around 4 separate stars by the HATNet Survey. One of these, the hot Saturn around HAT-P-51, is a promising target for measuring the Rossiter-McLaughlin effect.
