New observations of 14 faint, X-ray selected AGN indicate that a significant population of faint z ~ 5−6 AGNs should be detectable in deep X-ray surveys, but we don’t observe this. Why not?

Two supernovae are thought to have occurred within 100 pc in the last 10 Myr. What impact did they have on life on Earth? This study examines the many effects potentially due to these supernovae.

The stellar properties of stars with transiting planets are compared to those with transiting planets that orbit in their hosts’ habitable zones. The two populations do not appear to be statistically different.

The chaotic fanning of the Ophiuchus stellar stream that orbits the Milky Way may have been caused by the graviational potential of the rotating, triaxial bar-like structure located in the galactic bulge.

234 flaring binaries were identified in Kepler data of 1049 close binary pairs. These data indicate that binary flare activity levels depend in a predictable way on the binary’s orbital and rotation periods.

Based on analysis of results from 619 simulations, a simple formula is presented describing the final spin of the black hole resulting from the merger of two black holes with arbitrary masses and spins.
