The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- II: Stellar Atmospheric Parameters, Chemical Abundances and Distances
Matthias Steinmetz, Guillaume Guiglion, Paul J. McMillan +58
We present part 2 of the 6th and final Data Release (DR6 or FDR) of the Radial Velocity Experiment (RAVE), a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars rando…
Tracing the origin of the Aquarius Stream: I
Elizabeth Wylie-de Boer, Kenneth Freeman, Mary Williams +3
We present an abundance analysis of six member stars of the recently discovered Aquarius stream, in an attempt to ascertain whether this halo stream is real and, if so, to understa…
The Properties and Gaseous Environments of Powerful Classical Double Radio Galaxies
Ruth Daly, C. O'Dea, P. Kharb +3
The properties of a sample of 31 very powerful classical double radio galaxies with redshifts between zero and 1.8 are studied. The source velocities, beam powers, ambient gas dens…
First Light Results from the Hermes Spectrograph at the AAT
Andrew Sheinis, Borja Anguiano, Martin Asplund +60
The High Efficiency and Resolution Multi Element Spectrograph, HERMES, is a facility-class optical spectrograph for the Anglo-Australian Telescope (AAT). It is designed primarily f…
On the origin of the Hercules group: I. chemical signatures indicating the outer bar origin
Yusen Li, Kenneth Freeman, Helmut Jerjen +3
The Hercules kinematic group is a kinematic anomaly of stars observed in the solar neighbourhood (SNd). In this series of papers, we present a comprehensive study of this structure…
Mapping the tilt of the Milky Way bulge velocity ellipsoids with ARGOS and DR2
Iulia T. Simion, Juntai Shen, Sergey E. Koposov +4
Until the recent advent of Data Release 2 (DR2) and deep multi-object spectroscopy, it has been difficult to obtain 6-D phase space information for large numbers of stars be…
The Neutral Hydrogen Properties of Galaxies in Gas-rich Groups
Robert Džudžar, Virginia Kilborn, Gerhardt Meurer +23
We present an analysis of the integrated neutral hydrogen (HI) properties for 27 galaxies within nine low mass, gas-rich, late-type dominated groups which we denote "Choirs". We fi…
The slope of the Baryonic Tully-Fisher relation
Sebastián Gurovich, Kenneth Freeman, Helmut Jerjen +2
We present the results of a baryonic Tully-Fisher relation (BTFR) study for a local sample of relatively isolated disk galaxies. We derive a BTFR with a slope near 3 measured over…
Cryoscope: A Cryogenic Infrared Survey Telescope in Antarctica
Mansi M. Kasliwal, Nicholas Earley, Roger Smith +58
We present Cryoscope--a new 50 deg field-of-view, 1.2 m aperture, survey telescope to be located at Dome C, Antarctica. Cryoscope has an innovative optical-thermal d…
On the origin of the Hercules group: II. the Trojan quasi-periodic identity on the orbital level
Yusen Li, Kenneth Freeman, Helmut Jerjen
The Hercules kinematic group is a stellar anomaly structure observed in the solar neighbourhood (SNd). In the previous paper, we analysed chemical signatures and related the origin…
GNOSIS: the first instrument to use fibre Bragg gratings for OH suppression
Christopher Q. Trinh, Simon C. Ellis, Joss Bland-Hawthorn +20
GNOSIS is a prototype astrophotonic instrument that utilizes OH suppression fibres consisting of fibre Bragg gratings and photonic lanterns to suppress the 103 brightest atmospheri…
Galactoseismology: Discovery of a cluster of receding, variable halo stars
Sukanya Chakrabarti, Rodolfo Angeloni, Kenneth Freeman +13
A dynamical characterization of dark matter dominated dwarf galaxies from their observed effects on galactic disks (i.e. Galactoseismology) has remained an elusive goal. Here, we p…
Pseudo Three-dimensional Maps of the Diffuse Interstellar Band at 862 nm
Janez Kos, Tomaž Zwitter, Rosemary Wyse +20
The diffuse interstellar bands (DIBs) are absorption lines observed in visual and near infrared spectra of stars. Understanding their origin in the interstellar medium (ISM) is one…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- I: Survey Description, Spectra and Radial Velocities
Matthias Steinmetz, Gal Matijevic, Harry Enke +59
The Radial Velocity Experiment (RAVE) is a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars randomly selected in the southern hemisphere. The RAVE medium-resolutio…
Single-lined Spectroscopic Binary Star Candidates from a Combination of the RAVE and Gaia DR2 surveys
Danijela Birko, Tomaž Zwitter, Eva K. Grebel +11
The combination of the final version of the RAVE spectroscopic survey data release 6 with radial velocities and astrometry from Gaia DR2 allows us to identify and create a catalog…
