TL;DR: In this paper, a photonic spectrograph is used for accurately measuring and displaying spectra from radiation signals received from a telescope, where the optical signals output from the single-mode optical fibres are received by an optical manipulation device in the form of an array waveguide grating which selectively combines the singlemode signals into a continuous optical spectrum.

TL;DR: PRAXIS as discussed by the authors uses the same fibre Bragg gratings as GNOSIS in its first implementation, and will exploit new, cheaper and more efficient, multicore fiber Bragg grasps in the second implementation.

TL;DR: MagRite as discussed by the authors fits equilibrium models to simultaneously reproduce the surface brightness, rotation, and velocity dispersion profiles of a galaxy with a Srsic profile stellar bulge, exponential disk, and parametric dark-matter halo.

TL;DR: In this article, the authors explore the dependence of elemental abundances on stellar age and metallicity among Galactic disc stars and find that the abundance of most elements can be predicted from age and [Fe/H] with an intrinsic scatter of about 0.03 dex.
