A split-crystal neutron interferometer allows longer arm separation and length. However, since the visibility of the interference is sensitive to seismic and acoustic noise, it is crucial to design and operate the interferometer acknowledging this problem. To aid in this process, we present a mathematical model that quantifies how time-dependent accelerations affect the phase and visibility of the interference fringes.

Researchers demonstrate that superflow in a fermionic superfluid carries angular momentum quantized in units determined by the mass of the individual constituent particles, revealing a fundamental difference from how angular momentum behaves in bosonic condensates.

**_New Lasers for a Gigantic Virtual Telescope—A New Era for Interferometry_**** _| ESO_** "We have been working towards this for decades, and now the time has finally come. Last week, the European Southern Observatory’s Paranal Observatory was host to a show unlike any other as four lasers, one from each of the 8-meter telescopes of the Very Large Telescope (VLT), were projected into the skies. All in the name of science, of course." "In this Chasing Starlight episode, we will explore GRAVITY+, a massive upgrade to the European Southern Observatory’s VLT Interferometer and how new lasers are opening up the southern sky to this facility." GRAVITY+ was carried out by a consortium led by the Max Planck Institute for Extraterrestrial Physics.
