TL;DR: The Virgo detector has now finished its first science run; a science mode duty cycle of more than 80% and a 4.5 Mpc horizon distance for binary neutron star inspiral sources were achieved.

TL;DR: In this paper, the authors report on the constraints these observations place on the rate of binary black hole coalescences, and estimate a 90% credible range of merger rates between $2$--$53 \, \mathrm{Gpc}^{-3} \mathm{yr}^{ −1}$ (comoving frame).

TL;DR: Using data recorded by Advanced LIGO during its first observing run, no evidence for a background of any polarization is found, and the first direct bounds on the contributions of vector and scalar polarizations to the stochastic background are placed.

TL;DR: The automatic alignment system of the Virgo interferometer differs substantially from those used in similar experiments, since it uses a variant of the Anderson technique, and the main feature is a strong coupling of different degrees of freedom in the optical signals as mentioned in this paper.
