TL;DR: The GNOSIS as mentioned in this paper is a low-resolution spectrograph for low-resolved spectroscopy with fiber Bragg gratings, which has a resolving power of approximately 10,000.

TL;DR: The third public data release (DR3) of the Calar Alto Legacy Integral Field Area (CALIFA) survey as mentioned in this paper contains 1576 datacubes, including ~1.5 million independent spectra.

TL;DR: In this paper, the authors used the Hawaii Imaging Fabry-Perot Interferometer (HIFI) to map 150,000 H-alpha + (N II) lambda lambda 6548, 6583 emission-line profiles across the entire disk, with resolution 70 km/s at subarcsecond steps, down to a flux level of approximately 10(exp −17) ergs/s/sq cm (EM approximately equal to 4 cm(exp -6) pc).

TL;DR: In this paper, the authors presented direct kinematic evidence for bar streaming motions in two active galaxies with boxy stellar bulges, and used the Hawaii Imaging Fabry-Perot Interferometer to derive the two-dimensional velocity field of the line-emitting gas in the disks of the Sc galaxy NGC 3079 and the Sb galaxy nGC 4388.

TL;DR: In this paper, the authors analyzed the optical spectra of individual selected H II regions extracted from a sample of 350 spiral galaxies of the CALIFA survey and performed linear fitting to the abundances as a function of the de-projected galactocentric distances.
