TL;DR: In this paper, the authors demonstrated two alternative techniques of the optical readout of two-phase argon detectors, in the visible and NIR range, using a silicon photomultiplier matrix and electroluminescence due to either neutral bremsstrahlung or avalanche scintillation.

TL;DR: In this paper, the first results from a six-month long reverberation-mapping experiment in the ultraviolet based on 170 observations of the Seyfert 1 galaxy NGC 5548 with the Cosmic Origins Spectrograph on the Hubble Space Telescope are described.

TL;DR: In this paper, the authors present geometric and dynamical modeling of the broad line region for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014, using photometric and spectroscopic monitoring in the optical and ultraviolet, covering the H$\beta, C IV, and Ly$\alpha$ broad emission lines.

TL;DR: In this article, the sensitivity of a large scale two-phase liquid argon detector to the directionality of the dark matter signal was examined under the assumption that, above 50 keV of recoil energy, one can determine (with some resolution) the direction of the recoil nucleus without head-tail discrimination, as suggested by past studies that proposed to exploit the dependence of columnar recombination on the angle between the recoil direction and the electric field.
