N-body simulations show that unstable outer (>1 AU) giant planets can greatly reduce the multiplicity of inner super-Earths and leave the surviving population with large eccentricities and inclinations.

A multiwavelength study of three high-redshift blazars shows that inverse Compton scattering of low-energy photons supplied by the broad-line region can explain the X-ray and gamma-ray emission observed.

Detection efficiencies of the Palomar Transient Factory — a survey that has located 50,000 non-moving transient sources and spectroscopically confirmed 1900 supernovae — are presented in this study.

An extremely high-quality spectrum from Keck-HIRES of Kepler-11 reveal new values for its fundamental parameters that raise the calculated densities of its 6 planets by 20–95%, making them more typical.
Daniel Tamayo et al 2017 ApJL 840 L19
The configuration of the TRAPPIST-1 system of 7 planets is consistent with a history of slow, convergent disk migration resulting in its current long-lived resonant or near-resonant set of orbits.

The Large Magellanic Cloud Supernova Remnant Sample — the most complete SNR sample in any galaxy — implies SNRs should be the dominant mechanism for the production and acceleration of cosmic rays.
