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.

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.

Simulations with MESA demonstrate that mass loss through Roche-lobe overflow could transform a hot Jupiter into a lower-mass planet (such as a hot Neptune or super Earth).

Preliminary properties are reported for 7956 asteroids detected in the first year of the NEOWISE Reactivation mission. 201 of these are near-Earth asteroids; the rest are Main-Belt or Mars-crossing.

Radio transients resulting from the coalescence of a neutron star and a black hole may form a sub-population of fast radio bursts, distinguishable by a double peak with a precursor.

L. Fossati et al 2015 ApJ 812 L35

Observations of a sample of stars with transiting hot Jupiters support the theory that stars’ chromospheric activity may be masked if they are orbited by hot Jupiters with low surface gravity.
