Validating the Local Volume Mapper acquisition and guiding hardware
Maximilian Häberle, Thomas M. Herbst, Peter Bizenberger +13
The Local Volume Mapper (LVM) project is one of three surveys that form the Sloan Digital Sky Survey V. It will map the interstellar gas emission in a large fraction of the souther…
Planetary Candidates Observed by Kepler. VII. The First Fully Uniform Catalog Based on The Entire 48 Month Dataset (Q1-Q17 DR24)
Jeffrey L. Coughlin, F. Mullally, Susan E. Thompson +32
We present the seventh Kepler planet candidate catalog, which is the first to be based on the entire, uniformly processed, 48 month Kepler dataset. This is the first fully automate…
The Frequency of Carbon Stars Among Extremely Metal-Poor Stars
Judith G. Cohen, Stephen Shectman, Ian Thompson +6
We demonstrate that there are systematic scale errors in the [Fe/H] values determined by the Hamburg/ESO Survey (and by inference by the HK Survey in the past) for certain extremel…
A Novel Freeform Slicer IFU for the Magellan InfraRed Multi-Object Spectrograph (MIRMOS)
Maren Cosens, Nicholas P. Konidaris, Gwen C. Rudie +16
The Magellan InfraRed Multi-Object Spectrograph (MIRMOS) is a planned next generation multi-object and integral field spectrograph for the 6.5m Magellan telescopes at Las Campanas…
Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
Astro2020 APC White Paper: The MegaMapper: a z > 2 spectroscopic instrument for the study of Inflation and Dark Energy
David J. Schlegel, Juna A. Kollmeier, Greg Aldering +74
MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts at 2<z<5. A 6.5-m Magellan telescope will be coupled with DES…
Planetary Candidates Observed by Kepler VI: Planet Sample from Q1-Q16 (47 Months)
F. Mullally, Jeffrey L. Coughlin, Susan E. Thompson +56
\We present the sixth catalog of Kepler candidate planets based on nearly 4 years of high precision photometry. This catalog builds on the legacy of previous catalogs released by t…
A Spectroscopic Road Map for Cosmic Frontier: DESI, DESI-II, Stage-5
David J. Schlegel, Simone Ferraro, Greg Aldering +62
In this white paper, we present an experimental road map for spectroscopic experiments beyond DESI. DESI will be a transformative cosmological survey in the 2020s, mapping 40 milli…
Accurate Coordinates and 2MASS Cross-IDs for (Almost) All Gliese Catalog Stars
John Stauffer, Angelle M. Tanner, Geoffrey Bryden +10
We provide precise J2000, epoch 2000 coordinates and cross-identifications to sources in the 2MASS point source catalog for nearly all stars in the Gliese, Gliese and Jahreiss, and…
Carbon Stars in the Hamburg/ESO Survey: Abundances
Judith G. Cohen, Andrew McWilliam, Stephen Shectman +6
We have carried out a detailed abundance analysis for a sample of 16 carbon stars found among candidate extremely metal-poor (EMP) stars from the Hamburg/ESO Survey. We find that t…
A Precision Cryogenic Positioning Stage for Detector Dithering and Flexure Compensation
Stephen A. Smee, Stephen C. Hope, Randolph P. Hammond +20
This paper presents the design and technical progress of a precision X-Y stage for detector dithering and flexure compensation. The stage is being developed for use in the Magellan…
Key Technologies for the Wide Field Infrared Survey Telescope Coronagraph Instrument
Vanessa P. Bailey, Lee Armus, Bala Balasubramanian +84
The Wide Field Infrared Survey Telescope (WFIRST) Coronagraph Instrument (CGI) is a high-contrast imager and integral field spectrograph that will enable the study of exoplanets an…
The SDSS-V Local Volume Mapper (LVM): Scientific Motivation and Project Overview
Niv Drory, Guillermo A. Blanc, Kathryn Kreckel +48
We present the Sloan Digital Sky Survey V (SDSS-V) Local Volume Mapper (LVM). The LVM is an integral-field spectroscopic survey of the Milky Way, Magellanic Clouds, and of a sample…
Stellar Archaeology: a Keck Pilot Program on Extremely Metal- Poor Stars From the Hamburg/ESO Survey. III. The Lead (Pb) Star HE 0024-2523
Sara Lucatello, Raffaele Gratton, Judith G. Cohen +4
We present a detailed abundance analysis, including spectral syntheses, of a very metal-poor ([Fe/H]= -2.7), peculiar main sequence star, HE0024-2523 detected during the course of…
