TL;DR: In this article, the authors developed a new methodology for building spectral templates for galaxy redshifts, using the new templates for the FAST spectrograph as an example, and showed that a two-dimensional spectral classification of galaxy spectra can be developed using their emission- and absorption-line templates as physically orthogonal basis vectors.

TL;DR: The Zwicky catalog of galaxies (ZC) as discussed by the authors has been the basis for the Center for Astrophysics (CfA) redshift surveys based on it have relied on heterogeneous sets of galaxy coordinates and redshifts.

TL;DR: The Hectospec as discussed by the authors is a 300 optical fiber fed spectrograph, which was used at the MMT for observing configurations within ∼300 s, and to an accuracy of ∼25 μm.

TL;DR: The first example of a hypervelocity star ejected from the Galactic center, as predicted by Hills and later discussed by Yu & Tremaine, was discovered in this article. But the star's radial velocity vector points 174° from the galactic center, consistent with a Galactic center origin.

TL;DR: The first example of a hyper-velocity star ejected from the Galactic center as predicted by Hill and later discussed by Yu & Tremaine was discovered in this paper. But the star was a hot blue B9 main sequence star with a heliocentric distance of ~55 kpc.
