We report the realization of a large scale gravity antenna based on matter-wave interferometry, the MIGA project. This experiment consists in an array of cold Rb sources correlated by a 150 m long optical cavity. MIGA is in construction at…

The use of Immersed Gratings offers advantages for both space- and ground-based spectrographs. As diffraction takes place inside the high-index medium, the optical path difference and angular dispersion are boosted proportionally, thereby…
