Proceedings ArticleDOI
Post-inscription tuning of multicore fiber Bragg gratings
TL;DR: In this article, the authors present methods and results from experiments concerning the post-write tuning of fiber Bragg gratings in multicore fibers, which can be used to suppress one wavelength to a depth of 30 dB or greater.
Journal ArticleDOI

TL;DR: In this article, a semi-automated classification scheme was proposed to identify different types of peculiar spectral morphologies, in an effort to discover and flag potentially problematic spectra and thus help to preserve the integrity of the survey's results.
Journal ArticleDOI

TL;DR: In this paper, the impact of galaxy mergers on stellar kinematics was analyzed using Integral Field Spectroscopy (IFS) to detect and analyze galaxy interactions, including fly-bys.
Journal ArticleDOI

Gibson,Olivier Bienaymé,Julio F. Navarro,Quentin A. Parker,Warren A. Reid,Warren A. Reid,George M. Seabroke,Arnaud Siebert,Alessandro Siviero,Tomaž Zwitter +20 more
TL;DR: In this paper, the authors explore the correlations between velocity and metallicity and the possible distinct chemical signatures of the velocity over-densities of the local Galactic neighbourhood using the large spectroscopic survey RAVE and the Geneva Copenhagen Survey.
Journal ArticleDOI
Single-lined Spectroscopic Binary Star Candidates from a Combination of the RAVE and Gaia DR2 surveys
Danijela Birko,Tomaž Zwitter,Eva K. Grebel,Quentin A. Parker,Georges Kordopatis,Joss Bland-Hawthorn,Kenneth C. Freeman,Guillaume Guiglion,Bradley Kenneth Gibson,Julio F. Navarro,Warren A. Reid,George M. Seabroke,Matthias Steinmetz,Fred Watson +13 more
TL;DR: In this article, the authors combined the final version of the RAVE spectroscopic survey data release 6 with radial velocities and astrometry from Gaia DR2 to identify and create a catalog of single lined binary star candidates (SB1), their inferred orbital parameters, and to inspect possible double lined binary stars (SB2).
