The DESI Experiment Part I: Science,Targeting, and Survey Design
- Desi Collaboration Amir Aghamousa, J. Aguilar, +289 authors Y. Zu
- Physics
- 31 October 2016
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-space… Expand
A Gaia Data Release 2 catalogue of white dwarfs and a comparison with SDSS
- N. G. Fusillo, P. Tremblay, +16 authors J. H. University
- Physics
- 9 July 2018
We present a catalogue of white dwarf candidates selected from the second data release of Gaia (DR2). We used a sample of spectroscopically confirmed white dwarfs from the Sloan Digital Sky Survey… Expand
The second data release of the INT Photometric Hα Survey of the Northern Galactic Plane (IPHAS DR2)
- G. Barentsen, H. Farnhill, +50 authors A. Zijlstra
- Physics
- 18 June 2014
The INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is a 1800 deg2 imaging survey covering Galactic latitudes |b| < 5° and longitudes l = 30°–215° in the r, i, and Hα filters… Expand
White Dwarf Rotation as a Function of Mass and a Dichotomy of Mode Line Widths: Kepler Observations of 27 Pulsating DA White Dwarfs through K2 Campaign 8
- J. Hermes, B. Gaensicke, +15 authors S. Redfield
- Physics
- 20 September 2017
We present photometry and spectroscopy for 27 pulsating hydrogen-atmosphere white dwarfs (DAVs; a.k.a. ZZ Ceti stars) observed by the Kepler space telescope up to K2 Campaign 8, an extensive… Expand
The population of hot subdwarf stars studied with Gaia - I. The catalog of known hot subdwarf stars

Fundamental parameter accuracy of DA and DB white dwarfs in Gaia Data Release 2
- P. Tremblay, E. Cukanovaite, N. G. Fusillo, T. Cunningham, M. Hollands
- Physics
- 7 November 2018
We report on a comparison of spectroscopic analyses for hydrogen (DA) and helium atmosphere (DB) white dwarfs with Gaia Data Release 2 (DR2) parallaxes and photometry. We assume a reddening law and a… Expand
A photometric selection of white dwarf candidates in Sloan Digital Sky Survey Data Release 10
- N. G. Fusillo, B. Gaensicke, S. Greiss
- Physics
- 11 April 2015
We present a method which uses cuts in colour–colour and reduced proper motion–colour space to select white dwarfs without the recourse to spectroscopy while allowing an adjustable compromise between… Expand

- Physics
- 31 October 2016
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift-space distortions… Expand
Core crystallization and pile-up in the cooling sequence of evolving white dwarfs
- P. Tremblay, G. Fontaine, +7 authors T. Cunningham
- Physics, Medicine
- Nature
- 1 January 2019
White dwarfs are stellar embers depleted of nuclear energy sources that cool over billions of years1. These stars, which are supported by electron degeneracy pressure, reach densities of 107 grams… Expand
