SDSS-IV’s eBOSS will improve measurements of the cosmological distance scale by applying the Baryon Acoustic Oscillation method to quasar samples. eBOSS will survey over 500,000 new quasars.

Gemini Planet Imager observations 51 Eridani b further confirm that it is indeed a young exoplanet. It doesn’t appear to share the same orbital inclination as the M-dwarf orbiting 51 Eridani.

A wide-field survey of 557 Trojans shows that the mean g − i color decreases with decreasing size, consistent with the theory that red objects are converted to less-red fragments upon collision.

Thomas Peters et al 2015 ApJ 813 L27

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.

Evan N. Kirby et al 2015 ApJ 814 L7

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.
